Material for forming organic film, substrate for manufacturing semiconductor device, method for forming organic film, patterning process, and compound for forming organic film

Abstract

The present invention is a material for forming an organic film, containing: (A) a compound for forming an organic film shown by the following general formula (1A); and (B) an organic solvent, where W1 represents a tetravalent or hexavalent organic group, n1 represents an integer of 1 or 2, n2 represents 2 or 3, each R1 independently represents any in the following formula (1B), and a hydrogen atom of a benzene ring in the formula (1A) is optionally substituted with a fluorine atom. This provides: a compound having a dioxin structure, which is cured even under film formation conditions in inert gas, and which is capable of forming an organic underlayer film having not only excellent heat resistance and properties of filling and planarizing a pattern formed on a substrate, but also favorable film formability and adhesiveness to a substrate; and an organic film material containing the compound.
