Abstract The purpose of the present invention is to provide a copolymer and a positive resist composition, which make it possible to form a resist pattern that has a wide light exposure margin and a favorable shape. A copolymer according to the present invention is characterized by comprising a monomer unit (I) represented by formula (I) and a monomer unit (II) represented by formula (II). In the formulae, R1, R2, R3, R4, R5, R6, R7 and R8 each represent a specific group, and p represents an integer of 0 to 5 (inclusive). Le but de la présente invention est de fournir un copolymère et une composition de résine positive qui permettent de former un motif de résine ayant une large marge d'exposition à la lumière et une forme favorable. Un copolymère selon la présente invention est caractérisé en ce qu'il comprend une unité monomère (I) représentée par la formule (I) et une unité monomère (II) représentée par la formule (II). Dans les formules, R1, R2, R3, R4, R5, R6, R7 et R8 représentent chacun un groupe spécifique, et p représente un nombre entier de 0 à 5 (inclus). 本発明は、露光マージンが広く、かつ、良好な形状を有するレジストパターンを形成可能な共重合体およびポジ型レジスト組成物を提供することを目的とする。本発明の共重合体は、下記式(I)で表わされる単量体単位(I)と、下記式(II)で表わされる単量体単位(II)とを含むことを特徴とする。なお、式中、R1、R2、R3、R4、R5、R6、R7、R8は、それぞれ所定の基であり、pは、0以上5以下の整数である。
