发明名称 Patterning Method of Semiconductor Device
摘要 The invention relates to a patterning method of a semiconductor device. In an aspect of the invention, the method may include forming a target etch layer on a semiconductor substrate, forming a photoresist film on the target etch layer, forming photoresist patterns using exposure and development processes employing an exposure mask wherein exposure patterns, each having inclined top corners, are formed, and patterning the target etch layer using an etch process employing the photoresist patterns.
