Abstract:
A method for forming a gate pattern for a semiconductor device, comprising:forming an active area pattern of the semiconductor device, said active area pattern including active portions surrounded by isolation region portions;forming a photosensitive film on a conductive layer for the gate pattern above the active area pattern and the isolation region;exposing the photosensitive film by sequentially radiating with respective single shots of a radiation beam a plurality of butting unit regions defining butting portions between said butting unit regions;controlling said radiating of said butting unit regions so that said butting portions of said butting unit regions are formed only above the isolation region portions of the semiconductor device and not above the active portions of the active area pattern;developing the exposed photosensitive film; andetching the conductive layer to form the gate pattern such that the gate pattern extends over the active area pattern and the isolation region.
