摘要:
An exposure apparatus correction system comprising: a displacement calculator which calculates matching displacements between a first inspection pattern and a second inspection pattern, the first inspection pattern being transferred by an external first exposure apparatus, the second inspection pattern being positioned with respect to the first inspection pattern and transferred by a second exposure apparatus; an approximator which applies design coordinate systems and values of the calculated matching displacements to approximate expressions in which the matching displacements and a relationship between coordinate systems including the second inspection pattern is approximated by using a plurality of parameters, thereby allocating estimators to the plurality of respective parameters, the plurality of parameters having a mutually complementary relationship; a rounder which rounds estimators of the allocated estimators which are out of an effective range restricted by the second exposure apparatus to fall within the effective range; a back-calculator which defines the rounded estimators as new estimators and applies the new estimators and the design coordinate systems to the approximate expressions to calculate back calculation deviances which are expected to occur between the first inspection pattern and the second inspection pattern when the rounded values are used; a residual calculator which subtracts the calculation deviances from the matching displacements to obtain residuals; a corrected value calculator which utilizes the mutually complementary relationship between the plurality of parameters to calculate corrected values as values which reduce the residuals based on other parameters than the parameters whose estimators have been rounded in the plurality of parameters with respect to the other parameters; an adder which sequentially adds the new estimators and the corrected values and outputs results as a sum total of the estimators; an estimator memory which stores the sum total of the estimators; and a controller which allows the rounder, the back-calculator, the residual calculator, the corrected value calculator and the adder to cyclically perform repeated operations, and corrects the second exposure apparatus based on the sum total of the estimators stored in the estimator memory.

A semiconductor processing process control system includes a process controller main body (100) for controlling processes for semiconductor processing independently from semiconductor processing devices and contents of intended processing, and a control variable computation programs (210) for obtaining control conditions for semiconductor processing adaptive to semiconductor processing devices and contents of intended processing. The control variable computation programs (210) are used by plugging necessary one of them into the process controller main body (100). When there is any change in semiconductor processing device and content of processing, the system can cope with such changes by merely modifying the control variable computation programs (210). Therefore, the system flexibly, quickly copes with changes in process for processing, computing method of control variables and processing device.
摘要:
A semiconductor processing process control system comprising a skip judgment request receiving section for receiving a request for judgment as to whether a process can be skipped or not. A skip judgment yes/no section searches for a judgment plug-in corresponding to the process to be skipped and a judgment execute section activates the judgment plug-in to make a judgment as to whether the process can be skipped or not on the basis of skip judgment logic in the plug-in. A skip execute section effects skipping of the process if the judgment determines that the process can be skipped.
