View FPSBASE.ETP_TOOL_FAILURE_HIST
We define a failure when the tool_mfg_pct for the entire tool is 0% and at least one entity is UDT. If we have a mix of UDT, SDT, ENG, NST then we still consider this a failure as long as at least one entity is UDT. We may also have entities that are SBY but contributing 0% to the tool_pct. However if we have any PRD/SBY entities which contribute more than 0% then it is not a failure. We get this info from ETP_MNT_EPISODE_HIST for speed purposes then we have to add current failures from ETP_STATUS since they will not go in EPISODE_HIST until the entity comes up and the episode ends.

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) |

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) |
