Abstract:
Disclosed is a novel polysiloxane which is suitable for a resin component in a chemically amplified resist that is particularly excellent in I-D bias, depth of focus (DOF) and the like. Also disclosed are a novel silane compound useful as a raw material for synthesizing such a polysiloxane, and a radiation-sensitive resin composition containing such a polysiloxane. The silane compound is represented by the following formula (I). (I) The polysiloxane has a constitutional unit represented by the following formula (1). (1) (R represents an alkyl group; R and R respectively represent a fluorine atom, a lower alkyl group or a lower fluorinated alkyl group; n is 0 or 1; k is 1 or 2; and i is an integer of 0-10.) The radiation-sensitive resin composition contains such a polysiloxane and a radiation-sensitive acid generator.
