Patent ID: 8253077

Claim:
A substrate processing system for performing photolithography processing on a substrate to form a resist pattern on the substrate, said system comprising: a thermal processing unit for performing thermal processing on a substrate; an aligner for performing exposure processing on the substrate; a pattern dimension measuring unit for measuring a dimension of the resist pattern on the substrate; and a control unit configured to control said pattern dimension measuring unit to measure a first dimension of the resist pattern after the resist pattern is formed on the substrate, to control said thermal processing unit to perform temperature control of correcting a processing temperature of the thermal processing based on the measured first dimension from a previously obtained relation between a dimension of a resist pattern and a processing temperature of thermal processing during photolithography processing, and perform thermal processing at the corrected processing temperature, to control said pattern dimension measuring unit to measure a second dimension of the resist pattern after the resist pattern is formed on the substrate, and to control said thermal processing unit, said aligner, and said pattern dimension measuring unit to classify a distribution within the substrate of the measured second dimension into a linear component expressed by an approximated curved surface and a nonlinear component other than the linear component, dividing the linear component into a plurality of regions, correcting a processing condition of exposure processing for each of the regions based on the linear component in each of the regions from a previously obtained relation between a dimension of a resist pattern and a processing condition of exposure processing during photolithography processing, and controlling said thermal processing unit, said aligner, and said pattern dimension measuring unit to perform thermal processing at the corrected processing temperature and exposure processing under the corrected processing condition to form a determined resist pattern on a substrate.
