ABSTRACT:
In order to shorten the period for the development and manufacture of a semiconductor integrated circuit device, at the time of transferring integrated circuit patterns onto a wafer by an exposure process, a photomask PM1is used which is provided partially with light shielding patterns3aformed of a resist film, in addition to light shielding patterns formed of a metal.
