| 摘要 |
The invention provides a compound for forming an organic film having a partial structure represented by the following formula (vii-2), wherein R1 represents a linear, branched or cyclic monovalent hydrocarbon group having 1 to 20 carbon atoms, and a methylene group constituting R1 may be substituted by an oxygen atom; a+b is 1, 2 or 3; c and d are each independently 0, 1 or 2; x represents 0 or 1, when x=0, then a=c=0; L7 represents a linear, branched or cyclic divalent organic group having 1 to 20 carbon atoms, L8′ represents the partial structure represented by the following formula (i), 0≦̸o<1, 0<p≦̸1 and o+p=1, wherein the ring structures Ar3 represent a substituted or unsubstituted benzene ring or naphthalene ring; R0 represents a hydrogen atom or a linear, branched or cyclic monovalent organic group having 1 to 30 carbon atoms; and L0 represents a divalent organic group. There can be provided an organic film composition for forming an organic film having high dry etching resistance as well as advanced filling/planarizing characteristics. |
