Abstract: A method for switch dual Id verification systems for installing another carrier ID system on an equipment installation complying with SEMI E87. A first identification access system has internally installed on an equipment installation on which a second identification access system is then installed. Both systems are switched using a control flow and a wafer carrier ID is obtained by the chosen verification system.

Abstract: A system for controlling process parameters. The system contains first and second storage devices, and first and second processors. The first storage device stores first process parameters for the tools. The first processor retrieves the first process parameters from the first storage device and calculates a control limit for each of the tools accordingly. The second storage device stores the control limit information. The second processor receives second process parameters for the tool, retrieves corresponding control limit information from the second storage device, performs a statistical process control analysis accordingly, and generates an alarm signal for directing adjustment of the tool process parameters.

Abstract: A method and system for collecting, storing and accessing semiconductor manufacturing data in a storage entity are provided. The semiconductor manufacturing data is collected from at least one process tool and stored in a first predefined area of the storage entity until the data storing in the first predefined area is complete, at which time additional semiconductor manufacturing data may be stored in a second predefined area of the storage entity. After the storing of data in the first predefined area is complete, it may be accessed.

Abstract: The present invention relates to an apparatus and method for processing the flow of semiconductor wafers through a furnace tool having a front-opening unified pod (FOUP) material handling system. The invention provides for an automated control flow to realize greater efficiency and assure process quality. In one aspect of the invention the wafer batch completing its operation is discharged simultaneous with the charging of the next batch. Essentially the operation takes place by overlapping processing operations. An embodiment of the invention includes a process comprising the steps of: providing a first batch of semiconductor material, and loading the first batch into a carrier which transports the first batch into a semiconductor manufacturing process, and while the first batch undergoes the process, forming a second batch of semiconductor material, and pausing a second batch process operation until the first batch completes processing, to reduce the idle time of said process.

Abstract: A system for monitoring semiconductor testing tools comprises a tester testing a semiconductor device, whereby a test result is derived, a storage device storing a logic function corresponding to the semiconductor device, and a processor receiving the test result and the logic function from the tester and storage device respectively, and applying the logic function to the test result for validation.

Abstract: A system for dynamically monitoring the stability of manufacturing equipment comprises a process executor requesting a plurality of semi-manufactured products processed by the manufacturing equipment to be inspected at a first sampling rate and receiving a plurality of inspection results, a data processor analyzing the inspection results from the process executor to determine a second sampling rate, a storage device storing the second sampling rate, and a controller receiving the second sampling rate from the storage device and changing the first sampling rate of the inspection requested by the process executor to the second sampling rate.

Abstract: A system for managing quality control in a manufacturing plant for processing lots of work in process (WIP) for at least one product, comprises a manufacturing process which includes a manufacturing executive system (MES) which provides inspection data to a statistical process control (SPC) database, and an SPC analyzer for analyzing the inspection data and providing a sampling rate rule output to a sampling rate database. A server supplies the sampling rate rule to the MES. The MES tests a condition as to whether a lot of WIP should be sampled. If the condition is met, then provide an inspect control signal for inspection to the plant for inspecting the lot. If the condition is not met, then branch away from the control signal to provide an alternative control signal to pass on to the next process step in the plant.
