A positive resist composition comprising a hydroxypolyamide represented by the following general formula (I) and a photoactive component:
(wherein R1 and R3 may be the same or different and are each a tetravalent aromatic group; R2 is a bivalent aromatic group; n is an integer of 2 to 150; and Z is a monovalent organic group and at least 40% of Z is a group represented by the following structural formula (II):
-X-R4-(COOH)m (II)
(wherein X is a carbonyl group or a sulfonyl group; m is an integer of 0 to 3 with a proviso that m is not 0 when X is a carbonyl group; R4 is an aliphatic group not including alkenyl group or alkynyl group, an alicyclic group or an aromatic group; and, when X is a carbonyl group and R4 is an alicyclic group or an aromatic group, at least one of the carboxylic groups is at the ortho position)).
一种阳离子抗蚀剂组合物,包括由下式通式(I)表示的羟基聚酰胺和一种光活性成分:
(其中 R1 和 R3 可以相同或不同,且各自为四价芳香族基团;R2 为二价芳香族基团;n 为 2 至 150 的整数;Z 为一价有机基团,且至少 40% 的 Z 为由以下结构式(II)表示的基团:
-X-R4-(COOH)m (II)
(其中 X 是羰基或磺酰基;m 是 0 至 3 的整数,但当 X 是羰基时,m 不为 0;R4 是脂肪族基团,不包括烯基或炔基、脂环族基团或芳香族基团;当 X 是羰基且 R4 是脂环族基团或芳香族基团时,至少有一个羧基位于正交位置))。
