Patent ID: 8715913

Claim:
A silicon-containing resist underlayer film-forming composition containing at least any one of a condensation product and a hydrolysis condensation product or both of a mixture comprising: one or more kinds of a compound (A) selected from the group consisting of an organic boron compound shown by the following general formula (1) and a condensation product thereof and one or more kinds of a silicon compound (B) shown by the following general formula (2), R 1 m0 B(OH) m1 (OR) (3-m0-m1) (1) wherein R represents an organic group having 1 to 6 carbon atoms and optionally forming a cyclic organic group by bonding of two ORs; R 1 represents an organic group having a hydroxyl group or a carboxyl group substituted with an acid-labile group and optionally forming a cyclic organic group by bonding of two R 1 s; m0 represents 1 or 2, m1 represents 0, 1, or 2, and 1≦m0+m1≦3, R 10 m10 R 11 m11 R 12 m12 Si(OR 13 ) (4-m10-m11-m12) (2) wherein R 13 represents an organic group having 1 to 6 carbon atoms; each of R 10 , R 11 , and R 12 represents a hydrogen atom or a monovalent organic group having 1 to 30 carbon atoms; and m10, m11, and m12 represent 0 or 1, and 0≦m10+m11+m12≦3.
