    摘要: PURPOSE: A polymer, a photoresist composition comprising the same, a coating substrate using the same, and a photolithography pattern formation method using the same are provided to able to form a negative type image. CONSTITUTION: A polymer comprises a first unit formed from a monomer in chemical formula 1, and a second unit comprising a lactone portion. In chemical formula 1, L is a single bond, or a C1-C10 organic group, R1 is hydrogen, or a C1-C3 alkyl group, each R2 is independently hydrogen, or a C1-C10 organic group, each R3 is independently hydrogen, or a C1-C10 organic group, or randomly forms a ring together with combined common carbon atoms, and each R4 is independently a C1-C10 organic group, or forms a ring together with combined common carbon atoms. The polymer additionally comprises a third unit formed from a monomer which is acid-labile moiety, or alkyloxy (meth)acrylate.

    摘要: PURPOSE: A polymer, a photoresist composition comprising the same, a coating substrate using the same, and a photolithography pattern formation method using the same are provided to reduce thickness reduction at photolithography treatment, and to improve pattern collapse margin, dismemberment and photo rate, thereby capable of forming a negative image. CONSTITUTION: A polymer comprises a first unit formed from a monomer in chemical formula 1, and a second unit comprising a lactone portion. In chemical formula 1, R1 is a single bond, or a C1-C3 alkyl group, each R2 is independently hydrogen, or a C1-C10 organic group, each R3 is independently hydrogen, or a C1-C10 organic group, each R4 is independently a C1-10 organic group, or forms a ring together with combined common carbon atoms, and each R5 is independently a C1-C10 organic group, or randomly forms a ring together. The polymer additionally comprises a third unit different with the first unit and the second unit. The third unit comprises ether, ester, a polar group, or acid-labile moiety.
