Patent ID: 7947424

Claim:
A process for manufacturing a semiconductor device, characterized by comprising the steps of: coating an anti-reflective coating forming composition on a substrate and baking it to form an anti-reflective coating; wherein the anti-reflective coating forming composition comprises a resin produced by a condensation reaction between compounds of formula (1), wherein R 1 and R 2 are independently of each other hydrogen atom or an alkyl group, R 3 and R 4 are independently of each other hydrogen atom, methyl group, ethyl group, hydroxymethyl group or an alkoxymethyl group, and an acid and/or acid generator, the resin produced from the condensation reaction between compounds of formula (1) has a weight average molecular weight of 200 to 500,000, and the resin produced from compounds of formula (1) is contained in an amount of more than 50 mass % in a solid content of the anti-reflective coating forming composition; forming a photoresist on top of the anti-reflective coating; exposing the substrate covered with the anti-reflective coating and the photoresist with a light; developing it; transferring an image on the substrate by etching to form an integrated circuit device.
