Abstract:
A method of manufacturing semiconductor integrated circuit devices comprising relative to each semiconductor wafer of a group of plural semiconductor wafers:(a) a step of depositing a photosensitive organic film on a main surface of said semiconductor wafer; (b) a step of performing exposure processing on said semiconductor wafer; (c) a step of performing development processing on said semiconductor wafer; (d) a step of testing the semiconductor wafer after said development processing; (e) a step of removing the photosensitive organic film on said semiconductor wafer when said semiconductor wafer is determined as nonstandard by a result of said test; and (f) a consistent processing step for performing a processing for removing said photosensitive organic film in a processing unit for depositing the photosensitive organic film, and thereby connecting the step of removing said photosensitive organic film to the step of depositing said photosensitive organic film and repeating the steps following after the step of depositing said photosensitive organic film to regenerate said semiconductor wafer, wherein in a system for performing said consistent processing, other processing is automatically performed in parallel for other semiconductor wafers among said group of plural semiconductor wafers during the regeneration processing of said semiconductor wafer determined as nonstandard.
