ABSTRACT:
In a semiconductor device manufacturing method, the step of calculating an exposure time of a photoresist includes (a) a step of deciding whether or not a variation of a line width of a device pattern104or a resist pattern102ain a reference chip in a plurality of semiconductor wafers101that are manufactured in the past and have the same wafer information as an subject semiconductor wafer101is contained within a tolerance over a plurality of semiconductor wafers101in the past, and (b) a step of correcting the exposure time every chip by using an exposure correction table22if it is decided in the step (a) that the variation falls within the tolerance.
