Patent ID: 7923192

Claim:
A base material for a pattern-forming material, comprising a low molecular weight compound (X1), which is formed from a polyhydric phenol compound (x) that comprises two or more phenolic hydroxyl groups and satisfies conditions (1), (2), and (3) described below, wherein either a portion of, or all of, said phenolic hydroxyl groups are protected with acid dissociable, dissolution inhibiting groups, wherein the proportion within said base material of said low molecular weight compound (X1), in which either a portion of, or all of, said polyhydric phenol compound (x) are protected with acid dissociable, dissolution inhibiting groups, is greater than 80% by weight: (1) a molecular weight within a range from 450 to 1,500, (2) a molecular weight dispersity of no more than 1.5, and (3) an ability to form an amorphous film using a spin coating method.
