The present invention relates to a semiconductor device using a copolymer-containing photoresist, and a process for manufacturing the same. As a norbornene derivative (monomer) having a hydrophilic group is synthesized and introduced to the backbone chain of a polymer, the polymer according to the present invention has excellent etching resistance and heat resistance, which are the characteristic points of alicyclic olefin structure, and provide excellent resolution due to prominent enhancement of adhesiveness resulted from introducing a hydrophilic group (—OH).

The invention relates to a process for the preparation of an acrylate copolymer having a number average molecular weight of 400-2000 by polymerization of a monomer mixture consisting of 35-60 mole % of styrene and/or a-methyl styrene, 20-60 mole % of acrylic acid and/or methacrylic acid and 0-30 mole % of one or more other monovinyl compounds in the presence of a 2 to 8 carbon atoms-containing mercaptomonocarboxylic acid or mercaptodicarboxylic acid as chain length regulator in an amount of 0.05 to 0.2 moles per mole of the monomeric compounds, after which the resulting reaction product is brought into reaction with a glycidyl ester of a monocarboxylic acid. The invention also relates to a liquid coating composition having a solids content of at least 60% by weight based on the acrylate copolymer thus prepared and a curing agent.
