摘要:
In a photoresist composition including a blocking group less sensitive to a temperature during a PEB process, the photoresist composition comprising from about 2% to about 10% by weight of a photosensitive resin, from about 0.1% to about 0.5% by weight of a photoacid generator, and a residual amount of a solvent, the photosensitive resin including a blocking group having a weight average molecular weight of from about 70 to about 130.
