摘要:
A system, method and apparatus for resource reallocation based on ambient condition data is disclosed herein. The system includes a planning module (102) for configuring plan data to include a primary sequence and an auxiliary sequence, a rule table (116) for storing the auxiliary sequence, an ambient condition receiver (124) for receiving the ambient condition data, and a routing processor (126) for accessing the rule table (116) to allocate an auxiliary sequence in place of a primary sequence in the event that particular ambient data is received.
摘要:
A system and a method for managing a work-in-process (WIP) workload within a fabrication facility employ sequential processing of the work-in-process (WIP) workload within one each of a minimum of one pre-process tool, a minimum of one buffer tool and a minimum of one post-process tool. A buffer tool tolerance time is calculated predicated upon an available work-in-process (WIP) pre-process rate, an available work-in-process (WIP) buffer capacity and an available work-in-process (WIP) post process rate. The work-in-process (WIP) workload may thus be optimally processed in accord with the buffer tool tolerance time.
摘要:
A system and method are provided for calculating a plurality of bottleneck delta virtual work in process time (“VWIP”) values. Each of the bottleneck delta VWIP values represents the time until one of n bottleneck workstations begins to risk starvation. The calculating includes deriving one or more baseline cycle times based on an X-factors method.
摘要:
A process selection system and method enable the automatic control of the specification to equipment most suitable for each lot. Processing using this specific equipment can be performed by further selecting the most suitable equipment from equipment used for the product type. Since a plurality of equipment can be specified for each lot, the equipment can be specified from an equipment group having these plurality of equipment. The adequate number of products in process for each equipment-specific process equipment id can be calculated based on the distribution percentage ri. The equipment-specific process equipment having the maximum value of the differential Gi between the adequate number of products in process ni and the collected actual number of products in process can be determined as the equipment-specific process equipment for the lot.
摘要:
A computer system (10) and method for automating manufacture of a photomask. The computer system (10) has a product database (21) that stores information used to manufacture the photomask. In addition, a semiconductor device is manufactured using the information stored in the product database (21). The information is transmitted to the product database (21) from semiconductor satellite systems such as a fabrication facility (14), a first mask shop (12), and a second mask shop (13). The computer system (10) chooses a mask shop for producing the photomask by using the information transmitted form the first mask shop (12) and the second mask shop (13).
