Abstract:
1. A method of forming an insulating film between interconnect layers of a semiconductor device comprising the steps of: providing a liquid coating composition by dissolving a siloxane-based resin in an organic solvent; coating a silicon wafer with the liquid coating composition to form a coating film thereon; and heat-curing the coating film, wherein the siloxane-based resin is prepared by hydrolyzing and polycondensing a first monomer of the formula (1) and a second monomer of the formula (2) in an organic solvent in the presence of an acid or alkaline catalyst and water: wherein, R each of X m is an integer from 0 to 10; and p is an integer from 3 to 8; and wherein, R X Y n is an integer from 0 to 10.
