Photomasks and methods of manufacturing the same
摘要:
In a method of manufacturing a photomask pattern, a light-shielding layer pattern and an anti-reflective layer pattern are formed sequentially on a transparent substrate. Oxidation and nitridation processes are performed on a sidewall of the light-shielding layer pattern to form a protection layer pattern on a lateral portion of the light-shielding layer pattern.
