摘要

PROBLEM TO BE SOLVED: To provide a composition for formation of a passivation film having an excellent ability to reflect light.SOLUTION: A composition for formation of a semiconductor substrate passivation film comprises: an organic aluminum compound expressed by the general formula (I) below; and white particles. In the general formula (I), R's represent an alkyl group with 1-8 carbon atoms independently of each other; n represents an integer of 0-3; Xand Xrepresent an oxygen atom or a methylene group independently of each other; and R, Rand Rrepresent a hydrogen atom or an alkyl group with 1-8 carbon atoms independently of each other.
