FPSAPP.DASH_P_CURR_SHIFT_MOVES

INST

Time when the event occurred. (* inherited from FPSINPUT.WIP_EVENT_HIST)

LOT_SEQ_WITHIN_SEC

For rows with identical timestamps, sequence records to get proper sequence (* inherited from FPSINPUT.WIP_EVENT_HIST)

LOT

A lot is a group of units that process together. Usually lot_id or lot_number in MES. All units in a lot are in the same carrier but there may be multiple lots in a carrier. (* inherited from FPSINPUT.WIP_LOTS_STATIC)

PARENT_LOT

The parent lot should ideally be the original parent but it could be the most recent parent if multiple splits have occurred. (* inherited from FPSINPUT.WIP_LOTS_STATIC)

CARRIER

RFID of the cassette or FOUP the lot is currently in. (* inherited from FPSINPUT.MHS_CARRIERS)

EVENT

This is the event registered in the MES. This is for the historical record and display only. Each event is mapped to an FPS event_type and the event_type is what is used by FPS applications. (* inherited from FPSINPUT.WIP_EVENTS)

EVENT_TYPE

Event Type (* inherited from FPSINPUT.EQP_SCHED_EVENTS_MANUAL)

MOVE_TYPE

Move_type is populated with a value in WIP_MOVE_TYPES (COMP, ISKIP, etc.) for all records where is_next = Y. It is null when the qty changes but is_next = N and these "delta only" records will always have a delta_type. Note that it is possible and not unusual to have both move_type and delta_type when the lot both moves and changes qty with the same event. (* inherited from FPSBASE.WIP_STEP_HIST)

DELTA_TYPE

Delta_type is the reason why the qty changed. It is populated with a value in WIP_DELTA_TYPES (SCRAP, SPLIT, etc.) for all records where qty_delta != 0. It is null for normal moves where is_next = Y and the qty does not change. The logic to populate this is in WIP_STEP_HIST_INSERT_BEF. (* inherited from FPSADMIN.WIP_DELTA_TYPES)

IS_REPEAT_CURR_SHIFT

TOOL

Tool is generally just the main tool. The exception is when different entities on the tool run completely independently and it is physically impossible to run wafers of the same lot across multiple entities. In this exception case, we may want to assign the entities to different eqp_types and therefore we should define each entity as a tool. Please note that when we do this there is no indication whatsoever that these different entities are on the same tool. (* inherited from FPSINPUT.EQP_TOOLS)

ACTUAL_CH_USED

Here is where we can log the actual_ch_used directly if we know it. We have three ways to determine actual_ch_used in WIP_LOTS_REALTIME which populates WIP_STEP_HIST: 1) Log it directly in this colum for an event where the logged_entity is the main tool. 2) Log events to each of the chambers used in WIP_EVENT_HIST. 3) Log events to each of the chambers used in WIP_WAFER_HIST. (* inherited from FPSINPUT.WIP_EVENT_HIST)

ACTUAL_MACHINE_RECIPE

Machine recipe used to process the lot as logged during processing by the tool. (* inherited from FPSINPUT.WIP_EVENT_HIST)

PORT_MODE

PORT_MODE is the port equivalent to EQP_STATE. Examples might be AUTOMATIC, MANUAL, SEMI-AUTOMATIC, or DOWN. If configured in GEN_FACILITIES, the view DASH_P_TOOL_PORTS can overlay whether the port is occupied along with its carrier and the WIP processing states over the port modes as long as the port mode has is_up set to Y. Therefore it is not necessary to reflect occupied or empty when developing the ETL logic to populate the EQP_PORTS table. (* inherited from FPSINPUT.EQP_PORT_MODES)

IS_AUTO

This field shows if the port mode is set to automatically deliver material. If the facility either has automated delivery (aka 300mm) or is using semi-automated delivery (aka NextMove) then a port set to a port_mode where this is N but is_up is Y is considered manual. A manual port means that the delivery system cannot use this port. If all ports are manual then rank will be M (Ports Manual) and ETP will set the state to SBY-RANKM (Standby With All Ports in Manual). In addition, we report auto_pct by summarizing the port states in auto and manual. (* inherited from FPSINPUT.EQP_PORT_MODES)

ACTUAL_DURABLE_USED

Actual durable used as logged by the tool during processing of the lot. This can be a comma delimited string if multiple durables are used. (* inherited from FPSINPUT.WIP_EVENT_HIST)

DISPATCHED_BY

RESERVE_INST

Time when the lot was reserved to the tool either by Scheduler or external or manual reservation. As opposed to dispatch, reserve is only in the FPS DWH and therefore can be automatically undone. (* inherited from FPSBASE.WIP_STEP_HIST)

DISPATCH_INST

Time when the lot indicated in the MES that it will process on the tool. As opposed to reserve, dispatch cannot be automatically undone. (* inherited from FPSBASE.WIP_STEP_HIST)

READY_INST

Time when the lot was ready to be processed (e.g. after recipe downloaded). (* inherited from FPSBASE.WIP_STEP_HIST)

BEG_PROC_INST

time when the lot started processing on the main tool. (* inherited from FPSINPUT.WIP_STEP_HIST_MANUAL)

END_PROC_INST

time when the lot finished processing on the main tool. (* inherited from FPSINPUT.WIP_STEP_HIST_MANUAL)

QTY

Quantity of units in the lot according the qty_unit defined for the facility. It is required for all lots in each facility to have their qty defined in the same units therefore the change in the unit is critical to defining the facility. For example, a pretest facility might have a sort step in the middle where we learn the qty of die. Prior to this step we know only the wafer qty but after this step we know both wafer and die. Since wafer is the only qty we know throughput the flow then wafer must be defined as the qty unit for this facility. Die can then be populated as sec_qty when it is known. Similarly the wafer saw facility might have a step in the middle where we cut the wafers into die. After this step we no longer know the number of wafers which means that die must be the qty unit for this facility and wafers can be the sec_qty prior to the saw step. Please note that a lot with qty of 0 is allowed but only if the sec_qty is greater than 0. This is unusual but one case is where we know the wafers will be scrapped but cannot be scrapped quite yet. (* inherited from FPSINPUT.WIP_EVENT_HIST)

QTY_IN_JOB

The number of units in the job. For example a batch tool with 5 carriers each with a 25 wafer lot would have 125 in the job. This is also important for non-batch tools where we have multiple lots in a carrier as the job might include all lots or only selected lots. (* inherited from FPSBASE.WIP_LOT_HIST)

FIRST_LOT_IN_JOB

The first lot in the job determined by the order of events. When this first lot logs the first tool event which is usually a reserve or dispatch then the job_id is created with only this lot. Then subsequent lots join this job. While we use job_id to identify lots that will process or are processing or processed together, first_lot_in_job is still a useful field. (* inherited from FPSBASE.WIP_LOT_HIST)

IS_REWORK

Y indicates the lot is on a rework route after the event is logged. If a lot is reworked then returns to the main route and repeats some steps, is_rework will be N but we will count those steps as repeats. (* inherited from FPSINPUT.WIP_EVENT_HIST)

IS_REWORK_START

Event started rework (* inherited from FPSINPUT.WIP_EVENT_HIST)

IS_REWORK_END

Event ended rework (* inherited from FPSINPUT.WIP_EVENT_HIST)

EXPT_ID

Experiment identifier which indicates the lot will process differently that normal for its product on at least one step of the route. (* inherited from FPSINPUT.WIP_LOTS_STATIC)

EXPT_VARIATION

Assigned to sibling lots to indicate which variation of the experiment will be performed on the lot. For example, variation 0 might get the normal recipe while variation 1 might get a different recipe then we can compare the different wafers in each split at a following measurement or test step. (* inherited from FPSINPUT.RTG_TOOL_ASSIGNMENTS_LOT)

IS_EXPT_STEP

Flag set to Y if the experiment requires abnormal processing at this step. (* inherited from FPSBASE.WIP_LOT_HIST)

STEP_ENT_INST

Time when the lot entered the step. (* inherited from FPSBASE.WIP_LOT_HIST)

AGE

NEXT_FACILITY

Event moved the lot to this new facility (* inherited from FPSINPUT.WIP_EVENT_HIST)

NEXT_PRD

Event moved the lot to this new prd (* inherited from FPSINPUT.WIP_EVENT_HIST)

NEXT_PLANPRD

If this event results in the planprd of the lot changing the new value is stored here. (* inherited from FPSINPUT.WIP_EVENT_HIST)

NEXT_ROUTE

Event moved the lot to this new route (* inherited from FPSINPUT.WIP_EVENT_HIST)

NEXT_STEP

Event moved the lot to this new step (* inherited from FPSINPUT.WIP_EVENT_HIST)

NEXT_OPERATION

Operation of the next_step used primarily to determine is_oper_move. Populated by trigger. (* inherited from FPSBASE.WIP_LOT_HIST)

NEXT_PROCESS

Process of the next step. Populated by trigger. (* inherited from FPSBASE.WIP_LOT_HIST)

IS_OPER_MOVE

The critical Dashboard metric we call oper moves is moves according to the specific definition of the site, usually the moves calculation they used prior to installation of the FPS Dashboard. If Y then this step move meets the specific criteria for the site to be counted as an oper move. (* inherited from FPSBASE.WIP_STEP_HIST)

STEP_SEC_CURR_SHIFT

STEP_HOLD_SEC_CURR_SHIFT

Time on hold at the current step during the current shift (* inherited from FPSBASE.WIP_STEP_HIST)

FACILITY

Facility is included in almost every join in the DWH so this represents a definitive split. A route must have all steps on tools in the same facility. A tool must process all lots in the same facility. If your site has multiple buildings where lots run on routes using tools in multiple buildings then everything should be one facility. For example, multiple Fab buildings. But if your site has independent facilities like Fab and Test and Assembly where lot may progress from one to the next but on different routes then these should be different facilities. Since this column is in virtually every table it is critical that the value here is exactly matches what is in the MES if the MES has facility. Use facility_display for the display friendly name displayed in applications. See site_name comment for client/site/facility example. (* inherited from FPSINPUT.GEN_FACILITIES)

PRD

Prd determines the route which is used to process the lot in the facility and what tools, recipes, durables, etc. can be used at each step. Prd also determines the next facility for the lot when it finishes its route. For detailed information on prd vs. planprd see table comments in RTG_PLANPRDS. (* inherited from FPSINPUT.RTG_PRDS)

PLANPRD

Planning product used for all planning purposes. All lots with the same planprd are interchangeable to ship to the customer regardless of their prd, route, technology, wafer size, etc. For detailed information on prd vs. planprd see table comments in RTG_PLANPRDS. (* inherited from FPSINPUT.RTG_PLANPRDS)

ROUTE

Route that has threading requirements (* inherited from FPSINPUT.RTG_STEP_THREADING)

STEP

A single processing step within a route representing a single tool visit. Step is often a very complex string and should rarely be displayed. Instead we should use process_display. (* inherited from FPSINPUT.RTG_ROUTE_STEPS)

BANK

Lots which are not on a route are considered in a bank and the bank name indicates why the lot is off route. Bank must be NA for lots which are on a route. Our standard filter for active lots is bank = NA. (* inherited from FPSINPUT.RTG_BANKS)

IS_NONSTD

Our column to indicate non-standard processing at the step. For example, an experiment or a chain that is only active at a particular step or set of steps and then goes back to being normal for the route. If an experiment is severe enough that it affects the final product and has to be planned separately then it will be its own prd or planprd. (* inherited from FPSBASE.WIP_LOT_HIST)

LOT_TYPE

Lot_type is the base of the hierarchy that determines lot_family then lot_group. Ideally lot_type will come straight from the MES with little modification. (* inherited from FPSINPUT.WIP_LOT_TYPES)

LOT_FAMILY

Lot_family is a grouping of lot_type which is mainly use for goal planning. We set goals by family and are allowed to switch goals for different lots of different types within the family. We also report goal performance by family. (* inherited from FPSINPUT.WIP_LOT_FAMILIES)

LOT_GROUP

Lot_group is a grouping of lot_family and is the highest grouping in the lot type hierarchy. There should be only a few values for lot_group, i.e. Prod, Dev, TW. We group WIP and moves by lot_group on the dashboard and we group cycle time calculations by lot_group so this is an important field. (* inherited from FPSINPUT.WIP_LOT_GROUPS)

IS_TW

Our standard filter to exclude test wafers is is_tw = N but what we really mean with this filter is to exclude any lots that do not add value for the facility. Lots which add value including sellable, development, and engineering and these lot groups should have is_tw set to N. Lots which do not add value are commonly grouped together and named "test wafers" which is why this flag is named is_tw. These include true test wafers like monitors and quals and dummies but also could include virtual lots used for training or testing, bare wafers, or really anything else including in the MES as a lot which does not add value. All of these lot groups should have is_tw set to Y. You could argue that the is_tw field might be more accurately named is_value or is_valuable or is_prod_eng_dev but is_tw is generally clear to most people. Plus it has the advantage that it is short which is nice given how frequently we use the is_tw = N filter. (* inherited from FPSINPUT.WIP_LOT_GROUPS)

LOT_TYPE_SORT_ORDER

LOT_PRIORITY

CURR_PRIORITY_DISPLAY

LOT_PRIORITY_SORT

IS_LOT_PRTY_HIGHLIGHTED

PLAN_PRIORITY

Permanent priority of the lot set in the MES generally by planning. (* inherited from FPSINPUT.WIP_EVENT_HIST)

PLAN_PRIORITY_DISPLAY

PLAN_PRIORITY_SORT

IS_COUNT_PRIORITY_PCT

This flag determines which priorities to include in our overall percentage of priority lots in the Dashboard spotlight. This is similar to is_highlighted_prty but it is possible that we might want to highlight a priority but not include it in the percentage. (* inherited from FPSINPUT.WIP_PRIORITIES)

MODULE

Modules are departments of people who manage certain areas of the fab. The modules are assigned ownership of a set of tools to operate and maintain as well as steps on the route that they are responsible for executing. Since many of our tables include tool and step information together, we must distinguish between the owner of the step (WIP_MODULE), the owner of the operation of the tool (EQP_MODULE), and the owner of the maintenance of the tool (MNT_MODULE). WIP_MODULE is used to credit moves and set goals. Each route-step is assigned to a process family and then its wip_module is defined by the process family. EQP_MODULE is used to group tools particularly for tool performance reporting. Similar to WIP, each tool is dynamically assigned to a process family based on its assignments and then its eqp_module is defined by the process family. MNT_MODULE is usually the same as EQP_MODULE but unlike EQP_MODULE is not dependent on assignments but only on the EQP hierarchy. Each tool is assigned to an eqp_type and each eqp_type is assigned to a mnt_family and each mnt_family is assigned to a mnt_module. (* inherited from FPSINPUT.GEN_MODULES)

MODULE_DISPLAY

The name of the module displayed on all dashboards and reports. We allow a longer more descriptive name here although often this will be the same as the module. (* inherited from FPSINPUT.GEN_MODULES)

SHOULD_AUTO_HIDE

If the flag is set to Y then the module will be hidden on the Dashboard even if it has active WIP or moves. (* inherited from FPSINPUT.GEN_MODULES)

PROCESS

Process defines what occurs at a step. Different steps can share the same process if they are identical. Process should normally determine allowed tools and recipe although it can be overridden by step, route, prd, lot, and experiment for exceptions. Each process is dynamically assigned to one or more eqp_type-process_family combinations with use_pct. One process_family is determined to be primary. If grouping is done correctly, a process should only be one eqp_group with no crossover. (* inherited from FPSINPUT.RTG_PROCESSES)

PROCESS_DISPLAY

The name of the process displayed on all dashboards and reports. We allow a longer more descriptive name here although often this will be the same as the process. (* inherited from FPSINPUT.RTG_PROCESSES)

PROCESS_FAMILY

See https://help.inficonims.com/display/DW/Guide+to+Process+Families. (* inherited from FPSINPUT.RTG_PROCESS_FAMILIES)

PROCESS_SUBFAMILY

Route step family is used for the Dashboard to separate processes in a process family based on shared but limited assignments. It is also the base for GP subfamily. (* inherited from FPSBASE.RTG_ROUTE_STEPS_PLUS)

PROCESS_GROUP

Process group is the critical field where tools and processes come together for the purposes of Scheduler. Process group is in both EQP_TOOLS for the tools and in RTG_PROCESSES for processes. Ideally all tools that run the same set of processes with no crossover including back-up and emergency tools would be in the same process group but it is important to note that this is not technically required for Scheduler as long as all process groups are in the same sched group. (* inherited from FPSINPUT.RTG_PROCESS_GROUPS)

IS_IGNORE_WIP

This flag is in both RTG_OPERATION_FAMILIES and RTG_PROCESSES. If the value is Y for either the operation family or the process then we do not count WIP at the route-step towards the total for the facility. Typically this is set for staging operations. (* inherited from FPSINPUT.RTG_OPERATION_FAMILIES)

IS_STAGING_STEP

We expect large amounts of WIP and long cycle times at staging steps. We still calculate cycle time like any other step but the important difference is that lots currently at a staging step are not counted as normal coming lots to future steps. Instead we show them in a special column labeled From Staging. (* inherited from FPSINPUT.RTG_ROUTE_STEPS)

OPERATION

Operation is usually the primary level of routing in the MES and the level where the facility typically reports moves. FPS only allows one tool per step so our step is a lower level of routing than operation although both may be the same if the MES only allows one tool per operation. Note that because operation can include multiple steps and therefore multiple process families that we cannot have any association to equipment by operation. (* inherited from FPSINPUT.RTG_OPERATIONS)

OPERATION_DISPLAY

All xxx_display columns are used in place of the column xxx for display purposes. The values of these columns can be changed at any time without having to worry about other tables referencing it. (* inherited from FPSINPUT.RTG_OPERATIONS)

OPERATION_FAMILY

Grouping of route-step that is completely dependent on routing information from MES. The primary use of this field is for filtering on Operations Dashboard. Unfortunately for our database structure and naming convention, this field no longer has any link to operation. This is because operation is used primarily for Oper Moves and it is normal for steps in an operation to belong to multiple MES routing groups. For example, a sink step and a furnace step and a measurement step are in the same operation but each step belongs to the appropriate sink/furnace/measurement MES routing groups which we store in operation family. Since Dashboard already uses both operation and operation_family extensively and independently, we decided not to rename either column but simply remove the link. Please note that operation family is similar to process family and in fact they are often the same. The key differences are that operation family has nothing to do with equipment and that comes straight from ETL with no complex logic. Process family is the link between routing and equipment for the Operations Dashboard and therefore has complex logic. (* inherited from FPSINPUT.RTG_OPERATION_FAMILIES)

OPERATION_MODULE

LINE_SECTION

Large grouping of the line, e.g. FEOL, BEOL, Cu, etc. There should be only a handful of values for the entire facility - or if the facility only has one section then we can leave this column blank. (* inherited from FPSINPUT.RTG_LINE_SECTIONS)

CUSTOMER

Customer who will accept shipment of the lot. Currently this only used for grouping and filtering but in the future we might want to allow a customer to view a Dashboard only including their products. (* inherited from FPSINPUT.GEN_CUSTOMERS)

WAFER_SIZE

If the facility only has one wafer size then this column should be null in both RTG_PRDS and EQP_TYPES. If the facility has more than one wafer size then a value of null in EQP_TYPES means that those tools can run all wafer sizes. See column IS_ANY_WAFER_SIZE for details. (* inherited from FPSINPUT.GEN_WAFER_SIZES)

WAFER_SIZE_DISPLAY

The name of the wafer_size displayed on all dashboards and reports. We allow a longer more descriptive name here although often this will be the same as the wafer_size. (* inherited from FPSINPUT.GEN_WAFER_SIZES)

MAIN_ROUTE_FAMILY

Route family of the main route for the prd of the lot. (* inherited from FPSINPUT.WIP_OVR_OPER_MOVES_HIST)

MAIN_ROUTE_GROUP

Route group of main route. Often referred to as technology. (* inherited from FPSBASE.WIP_FLUSH)

ROUTE_SEGMENT

Route_segment allows for clear hierarchical segment organization for Segment Summary and Line Viewer on Dashboard. This is often referred to as stage and typically will come from the MES (as opposed to facility_segment which we will typically have to define for our purposes). We recommend that all routes in the same route family have the same route segments in the same order so that the Line Viewer by route family will be consistent but if this is not the case then we approximate the order as best we can. (* inherited from FPSINPUT.RTG_ROUTE_STEPS)

FACILITY_SEGMENT

Facility segment is the parent of common step and is used as the highest level grouping when we show WIP for a route group or the entire facility where we cannot use route segment. We would prefer somewhere between 8 and 20 facility segments. Typically we will have to define these (as opposed to route_segment which we will typically come from the MES). There is no RTG_FACILITY_SEGMENTS table because sorting of facility segments is determined by common_step_sort. A trigger on RTG_COMMON_STEPS ensures that facility segments are contiguous when the entire facility is sorted by common step. (* inherited from FPSINPUT.RTG_COMMON_STEPS)

EQP_MODULE

EQP_MODULE is the module responsible for operating the tool. See comments on the module column in GEN_MODULES for info on this column and how it relates to eqp_module and mnt_module. (* inherited from FPSBASE.EQP_TOOLS_PLUS)

EQP_PROCESS_FAMILY

IS_OPER_COMP
