Abstract

The present invention aims to provide an addition-curable silicone resin composition which exhibits good adhesion to a substrate and has good compatibility with an inorganic filler, as well as a cured product thereof, and a highly reliable semiconductor device encapsulated with the cured productAn addition-curable silicone resin composition is provided, which comprises:(A) a linear or branched organopolysiloxane having at least one alkenyl group, said organopolysiloxane comprising at least one unit selected from R¹R²SiO_2/2and R¹R²₂SiO_1/2units, and at least one unit selected from R^2'₂SiO_2/2, R^2'₃SiO_1/2and R^2'SiO_3/2units, wherein the percentage of the total number of the R¹R²SiO_2/2and R¹R²₂SiO_1/2units, relative to the total number of all siloxane units, is from 0.001% to 50%, and wherein R¹is, independently at each occurrence, a hydroxy group or an alkoxy group of 1 to 30 carbon atoms; R²is, independently at each occurrence, a group selected from a substituted or unsubstituted saturated hydrocarbon group of 1 to 12 carbon atoms, a substituted or unsubstituted aromatic hydrocarbon group of 6 to 12 carbon atoms, an alkenyl group of 2 to 10 carbon atoms, and the groups as defined for R¹; and R^2'is a group selected from the groups as defined for R²other than those as defined for R¹, with the proviso that at least one of R²and R^2'is an alkenyl group;(B) an organohydrogenpolysiloxane having at least two hydrosilyl groups, in an amount such that the ratio of the number of hydrosilyl groups in component (B) to the total number of alkenyl groups in component (A) is from 0.1 to 4; and(C) a catalytic amount of a hydrosilylation catalyst.
