FPSADMIN.RTG_DURABLE_ASSIGNMENTS

FACILITY

VARCHAR2(6)

N

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. (* from FPSINPUT.GEN_FACILITIES)

PROCESS

VARCHAR2(50)

N

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. (* from FPSINPUT.RTG_PROCESSES)

TOOL

VARCHAR2(16)

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. (* from FPSINPUT.EQP_TOOLS)

STEP

VARCHAR2(256)

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. (* from FPSINPUT.RTG_ROUTE_STEPS)

ROUTE

VARCHAR2(256)

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

PRD

VARCHAR2(64)

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. (* from FPSINPUT.RTG_PRDS)

LOT

VARCHAR2(32)

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. (* from FPSINPUT.WIP_LOTS_STATIC)

DURABLE_FAMILY

VARCHAR2(64)

N

Durable_family indicates what durable is required by the process. When multiple durables are in a family any of them can be used. Typically there is only one reticle per family and therefore the durable and durable_family are the same. The exception would be a high running product with backup reticles. However for probe cards it is common to have several cards for each product so we have several durables with the same family. (* from FPSINPUT.RTG_DURABLE_FAMILIES)

EXTL_RANK

VARCHAR2(1)

Allowed values are P, F, W. For details on all EXTL columns please see Help Site page at https://help.finalphasesystems.com/display/SCHED/Scheduler+and+External+Model+Status. (* from FPSINPUT.RTG_TOOL_ASSIGNMENTS)

IS_MULTIPLE_REQUIRED

CHAR(1)

When more than one durable family of the same durable class is assigned to the same criteria, we use this field to determine whether to choose one or whether we need all. Our default indicated by N is that any of them can be used. Occasionally certain processes require multiple durables of the same group (i.e. double reticles) and you indicate this by setting this column to Y.

PERM_RANK

VARCHAR2(1)

Permanent rank is typically loaded by ETL from a combination of the MES, recipe management system, and existing preference logic already used at the site. Possible values are in FPSADMIN.RTG_PERM_RANKS. (* from FPSINPUT.RTG_TOOL_ASSIGNMENTS)

TEMP_RANK

VARCHAR2(1)

Temporary rank should only be set manually by a human user, never loaded automatically by ETL. Possible values are in FPSADMIN.RTG_PERM_RANKS. (* from FPSINPUT.RTG_TOOL_ASSIGNMENTS)
