    摘要: Provided is a hydrophobic negative tone developable (NTD) resist composition comprising (a) a hydrophobic polymer having (i) at least one nonpolar acid-stable group; and (ii) at least one nonpolar acid-labile group, and (b) a photoacid generator (PAG) that may or may not be bound to the polymer, wherein a nonpolar aromatic or aliphatic organic hydrocarbon solvent is used to develop the unexposed regions of the NTD resist film and the resist film is not developable in an aqueous base developer, such as 0.26 N TMAH.
