HYDROSILYL-CONTAINING ORGANOPOLYSILOXANE, MAKING METHOD, ADDITION CURABLE SILICONE COMPOSITION, AND SEMICONDUCTOR PACKAGE

摘要

An organopolysiloxane having at least 4 terminal hydrosilyl groups per molecule is novel. Also provided is an addition curable silicone composition comprising (A) a linear organopolysiloxane having at least two alkenyl groups per molecule, (B) an organopolysiloxane having at least 4 terminal hydrosilyl groups per molecule, and (C) a hydrosilylation catalyst.
