FPSINPUT.ECTA_P_H_LOT_STEP

INST

Time when the event occurred. (* 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)

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)

ROUTE

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

MAIN_ROUTE

Primary route used by the prd. Excludes rework and alternate routing. We allow this column to be null in WIP_LOTS_VERIFY because we may not be certain what the main route is when we fix for missed events. In that event we trust the WIP_EVENT_HIST triggers has loaded the correct information into WIP_EVENTS_CURR_STEP. (* inherited from FPSINPUT.WIP_EVENT_HIST)

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)

STEP_ENT_INST

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

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_FAMILY

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

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)

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)

SEQ_NUM

Sequence number of step in route (* inherited from FPSINPUT.RTG_ROUTE_STEPS)

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)

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)

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)

PRTY_CTM_GROUP

This is one of the primary keys of our CTM tables. We use this group rather than the priority because we often have several different priorities which are close and are expected to have the same cycle time. (* inherited from FPSINPUT.WIP_PRIORITIES)

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)

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)

ROUTE_GROUP

Route_group is the parent of route_family. Route_group is used on the Dashboard and other applications as a large grouping for filtering. At many sites this is referred to as technology. (* inherited from FPSINPUT.RTG_ROUTE_GROUPS)

ROUTE_FAMILY

Route_family indicates that all routes within the family have similar or even identical steps and have the same segments. At facilities where various prds share the same route it is likely that the route will be the route_family. This is sometimes referred to as the main process flow. It is used on Segment Summary and Line Viewer to group similar routes. (* inherited from FPSINPUT.RTG_ROUTE_FAMILIES)
