Abstract: A control system for a semiconductor processing apparatus comprises a control server connected to a semiconductor processing apparatus, a verification server connected to the control server, and a database connected to the verification server. The verification server evaluates input parameter values stored in the semiconductor processing apparatus against verification data stored in the database. The results of the evaluation are used to determine whether a process will be performed by the semiconductor processing apparatus.

Abstract: A method for preventing process errors in a semiconductor fabricating process allows only a few authorized engineers to release interlocks of semiconductor fabricating equipment when a count of interlock occurrences exceeds a predetermined number within a predetermined period of time. By allowing a semiconductor fabricating equipment operator only limited ability to reset equipment interlocks, repeated interlock conditions caused by test specification failures may be over-ridden only a predetermined number of times before the semiconductor fabricating equipment is disabled completely. The disabled semiconductor fabricating equipment may only be re-enabled using an authorization code, which is only made available to selected personnel, thereby ensuring that necessary repairs and corrections have been implemented on the semiconductor fabricating equipment.

Abstract: A method for controlling semiconductor processing equipment in real time, includes measuring a characteristic value of a product of a first process performed by a first piece of equipment. Then it is determined whether the characteristic value of the product is within a predetermined acceptable product range stored in a host computer. A second process is stopped from operating on the product when the product is not within the range. Otherwise, when the product is within range, the process is tested using a main test that includes computing a main statistic using the characteristic value of the product and determining whether the main statistic is within a predetermined control limit range. Then, if the main test is not passed, the process is interrupted, including stopping the first piece of equipment and postponing the second process from operating on the product.
