摘要: A polymer comprises recurring units of formula (1) and recurring units having acid labile groups which units increase alkali solubility as a result of the acid labile groups being decomposed under the action of acid, and has a Mw of 1,000-500,000. R1 and R2 each are hydrogen, hydroxyl, hydroxyalkyl, alkyl, alkoxy or halogen, and n is 0, 1, 2, 3 or 4. The polymer is useful as a base resin to form a chemically amplified, positive resist composition which has advantages including a significantly enhanced contrast of alkali dissolution rate before and after exposure, high sensitivity, high resolution, and high etching resistance and is best suited as a micropatterning material for use in VLSI manufacture.

摘要: A dendritic or hyperbranched polymer having a weight average molecular weight of 500-10,000,000 is prepared by polymerizing a hydroxystyrene derivative, adding a branching monomer midway in the polymerization step to introduce branch chains, and repeating the polymerizing and branching steps. The polymer is advantageously used as the base resin of resist material because the size of the polymer can be reduced while maintaining strength.
