FPSBASE.DASH_P_H_SCRAP

START_SHIFT

Shifts can be of any length and it is important that all queries get the shift length based on start_shift and end_shift rather than assuming a set number of hours. (* inherited from FPSINPUT.CAL_SHIFTS)

START_PLAN_DAY

Plan days must be 24 hours in length and the start of the plan day must be the start of one of the shifts. Contrast this to plan day which is independent of shift. (* inherited from FPSINPUT.CAL_PLAN_DAYS)

START_WORK_DAY

Work days must be 24 hours in length and the start of the work day must be the start of one of the shifts. Contrast this to plan day which is independent of shift. (* inherited from FPSINPUT.CAL_WORK_DAYS)

IS_CURR_SHIFT

IS_CURR_PLAN_DAY

IS_CURR_WORK_DAY

PLAN_DAY

Name of plan day must be unique and can be in any format as long as it is display friendly since this is what we show everywhere. We prefer that other tables should reference start_plan_day rather than plan_day in case we want to change the naming convention for the plan_day. (* inherited from FPSINPUT.CAL_PLAN_DAYS)

WORK_DAY

SHIFT

Name of shift must be unique and can be in any format as long as it is display friendly since this is what we show everywhere. We prefer that other tables should reference start_shift rather than shift in case we want to change the naming convention for the shift. (* inherited from FPSINPUT.CAL_SHIFTS)

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)

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)

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)

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)

SCRAP_OWNER

Engineer responsible for analyzing and recording this scrap event. (* inherited from FPSINPUT.WIP_EVENT_HIST)

SCRAP_CATEGORY

A optional categorization field for scrap events which can be defined for the facility. (* inherited from FPSINPUT.WIP_EVENT_HIST)

SCRAP_COMMENT

OPERATOR

In history tables, this is the username of the person or system who logged the event. In EQP_MNT_FUTURE, this is the username of the person who input the information about the maintenance event. Usernames can be looked up in GEN_USERS to get full names, email address, etc. Please note that the existence of each username in GEN_USERS is optional, meaning that it is never required for the username logged in the operator column to be in GEN_USERS. (* inherited from FPSINPUT.WIP_EVENT_HIST)

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)

LAST_TOOL

For rework and scrap events we automatically look up the last tool where the lot processed including metrology tools. (* inherited from FPSBASE.WIP_LOT_HIST)

LAST_TOOL_INST

LAST_PROCESS_TOOL

For rework and scrap events we automatically look up the last process tool for the lot. Process tool is determined by the process class of the tool and excludes metrology and support tools. It is likely this was the cause of the rework or scrap although by no means certain. (* inherited from FPSBASE.WIP_LOT_HIST)

LAST_PROCESS_TOOL_INST

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)

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)

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)

BUILDING

Building is the top of our MHS hierarchy at each site. It is independent of facility which is at the top of our EQP/RTG hierarchy. It is possible for a building to include multiple facilities and for a facility to include multiple buildings but we do not even need to define these relationships because EQP_TOOLS determines this by the combination of the facility and bay columns (since bay points to building). (* inherited from FPSINPUT.MHS_BUILDINGS)

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)

LOT_TYPE_SORT_ORDER

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_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_PLAN_PRTY_HIGHLIGHTED

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)

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_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)

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)

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)

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)

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)

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)
