摘要:
In a method of manufacturing a semiconductor device, a mask layer and a first layer may be sequentially formed on a substrate. The first layer may be patterned by a photolithography process to form a first pattern. A silicon oxide layer may be formed on the first pattern. A coating pattern including silicon may be formed on the silicon oxide layer. The mask layer may be etched using a second pattern as an etching mask to form a mask pattern, and the second pattern may includes the first pattern, the silicon oxide layer and the coating pattern. The mask pattern may have a uniform size.

Provided are a coating composition for deep ultraviolet (DUV) filtering during an extreme ultraviolet (EUV) exposure, the coating composition including about 100 parts by weight of a solvent including a first solvent (the first solvent being an alcoholic solvent); and about 0.05 parts by weight to about 5 parts by weight of a coating polymer having a degree of absorption of about 50%/μm or greater with respect to 193-nm incident light.
