  • HYPERBRANCHED POLYMER SYNTHESIZING METHOD, HYPERBRANCHED POLYMER, RESIST COMPOSITION, SEMICONDUCTOR INTEGRATED CIRCUIT, AND SEMICONDUCTOR INTEGRATED CIRCUIT FABRICATION METHOD
    Publication number: 20110198730
    Abstract: A method of synthesizing a hyperbranched polymer by living radical polymerization of a monomer in the presence of a metal catalyst includes at least adding a compound or setting the amount of the monomer in the living radical polymerization. The compound added is at least a compound represented by R1-A or a compound represented by R2—B—R3, where R1 denotes hydrogen, an alkyl group (1-10 carbons), aryl group (1-10 carbons), or aralkyl group (7-10 carbons), A denotes a cyano group, hydroxyl group, or nitro group, R2 and R3 denote hydrogen, alkyl groups (1-10 carbons), aryl groups (6-10 carbons), aralkyl groups (7-10 carbons), or dialkylamino groups (2-10 carbons), and B denotes a carbonyl group or sulfonyl group. Setting of the monomer amount includes setting the amount of monomer to be mixed into a reaction system at one mixing to be less than the total monomer to be mixed with the reaction system.
