Patent ID: 8048615

Claim:
A method for manufacturing a semiconductor device, comprising: applying an organic coating forming composition on a substrate to form an organic coating; applying an underlayer coating forming composition on the organic coating to form an applied coating and irradiating the applied coating with light to form an underlayer coating, wherein the underlayer coating forming composition comprises: a polymerizable compound containing 5 to 45% by mass of silicon atom (A), a photopolymerization initiator (B), and a solvent (C); applying a photoresist composition on the underlayer coating to form a photoresist coating; exposing the photoresist coating to light; developing the photoresist after exposure to light to obtain a resist pattern; etching the underlayer coating according to the resist pattern; etching the organic coating according to the patterned underlayer coating; and processing the semiconductor substrate according to the patterned organic coating.
