FPSBASE.WIP_OPER_MOVES_LAST_DAY

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)

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)

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)

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)

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)

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_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_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_REWORK_MOVE

IS_REWORK_STEP

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)

NEXT_STEP

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

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)

NEXT_BANK

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

ROUTE

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

NEXT_ROUTE

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

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)

NEXT_MAIN_ROUTE

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

MAIN_RT_STEP

When lot is on a rework or alternate route, this is the step where it will return to the main route. We use this for planning purposes so we can calculate remaining steps. We allow this column to be null in WIP_LOTS_VERIFY because we may not be certain what the main route step 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)

NEXT_MAIN_RT_STEP

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

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)

NEXT_OPERATION

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

CURR_OPERATION

CURR_NEXT_OPERATION

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)

NEXT_PRD

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

NEXT_FACILITY

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