摘要: A three-component chemical amplified photoresist composition, comprising: an alkali soluble resin; a dissolution inhibitor of aromatic polyhydroxy compound substituted by at least two acid-decomposable radicals; and a photo acid generating agent of an onium salt, which is capable of forming good profiles when exposed to light with a short wavelength and is superior in heat resistance and storage stability.
