Abstract
A compound for forming an organic film shown by the formula (1A),
RX)m1 (1A)
wherein R represents a single bond or an organic group having 1 to 50 carbon atoms; X represents a group shown by formula (1B); and m1 represents an integer satisfying 2≤m1≤10,
wherein X2 represents a divalent organic group having 1 to 10 carbon atoms; n1 represents 0 or 1; n2 represents 1 or 2; X3 represents a group shown by the formula (1C); and n5 represents 0, 1, or 2,
wherein R10 represents a hydrogen atom or a saturated or unsaturated hydrocarbon group having 1 to 10 carbon atoms, wherein a hydrogen atom of the benzene ring in formula (1C) may be substituted with a methyl group or methoxy group. This compound for forming an organic film can provide organic film composition having good dry etching resistance, heat resistance to 400° C. or higher, high filling and planarizing properties.
