Disclosed is a curable composition including a silicone (A) of a specific structure and a composition containing Si&#x2014;OH group and Si&#x2014;H group, a silicone (B) of a specific structure and a composition containing Si&#x2014;OH group and Si&#x2014;CH&#x2550;CHgroup, and a hydrosilylation catalyst of a catalytic quantity containing at least one metal compound selected from the group consisting of platinum compounds, palladium compounds, and rhodium compounds. In this curable composition, as kind of each silicone and the content of Si&#x2014;OH group are adjusted, in curing the silicone, foaming in a cured product can be inhibited by inhibiting a dehydration condensation reaction between Si&#x2014;OH groups, as compared with a hydrosilylation reaction which is a reaction of Si&#x2014;CH&#x2550;CHgroup and Si&#x2014;H group. Furthermore, an excellent adhesion to a base body such as semiconductor substrate can be given when making a cured film.

Curable composition containing silicone, and cured product thereof

A composition containing a metal compound and a siloxane compound (A) represented by general formula (1): wherein X is represented by general formula X1 or X2: wherein the number of X1 is 1-8; the number of X2 is 0-7; the sum of the number of X1 and the number of X2 is 8; Rto Rrepresent a hydrogen atom, a Calkyl group, alkenyl group, alkynyl group, or a Caryl group, a hydrogen atom thereof optionally being substituted by a fluorine atom; Rrepresents a Calkyl group, alkenyl group, alkynyl group or aryl group, a hydrogen atom thereof being optionally substituted by a fluorine atom, a carbon atom being optionally substituted by an oxygen atom or a nitrogen atom; Rrepresents a hydrogen atom, a vinyl group or an allyl group; m and n represent an integer of 1-4; and 3&#x2266;m+n.
