Abstract:
In a method of manufacturing a semiconductor device, a wave-type slit is formed a wave-type slit in a stack structure, using an exposure mask including light transmission holes.

Claim (Index 5):
The method of  claim 3 , wherein the second photolithography process includes:\n forming a second mask layer on the stack structure; forming a second photoresist layer on the second mask layer; forming an exposure region and a non-exposure region in the second photoresist layer, by exposing the second photoresist layer through the light transmission holes, the exposure region corresponding to the light irradiation region and the non-exposure region corresponding to the reversed shape with respect to the light irradiation region; forming a second photoresist pattern by removing the non-exposure region; forming a second mask pattern having a trench corresponding to the non-exposure region by etching the second mask layer through an etching process using the second photoresist pattern as an etching barrier; and forming the first slit by etching the stack structure exposed through the trench through an etching process using the second mask pattern as an etching barrier.
