Abstract:
1. A method of forming an insulating film between interconnecting layers of a semiconductor device, the method comprising the steps of: providing a liquid coating composition by dissolving a siloxane-based resin in an organic solvent, wherein the siloxane-based resin is prepared by hydrolyzing and polycondensing a first monomer of a Formula 1 and a second monomer of a Formula 2 in an organic solvent in the presence of an acid or alkaline catalyst and water; coating a silicon wafer with the liquid coating composition to form a coating film thereon; and heat-curing the coating film, wherein the Formula 1 is wherein R 1 is a hydrogen atom, a C 1-13 alkyl group or a C 6-15 aryl group; each of X 1 , X 2 and X 3 , independently, is a C 1-3 alkyl group, a C 1-10 alkoxy group or a halogen atom provided at least one of said C 1-3 alkyl group, said C 1-10 alkoxy group or said halogen atom is hydrolysable; m is an integer from 0 to 10; and p is an integer from 3 to 8; and the Formula 2 is wherein R
