Abstract:
1. A method of manufacturing a semiconductor device sealed in a cured silicone body by placing a semiconductor device into a mold and subjecting a curable silicone composition that fills the spaces between said mold and said semiconductor device to compression molding, wherein said curable silicone composition comprises the following components: (A) an organopolysiloxane having at least two alkenyl groups per molecule; (B) an organopolysiloxane having at least two silicon-bonded hydrogen atoms per molecule; (C) a platinum-type catalyst; and (D) a filler, wherein either said component (A) contains siloxane units of formula RSiO 3/2 (where R is a univalent hydrocarbon group) and/or siloxane units of formula SiO 4/2 , or said component (B) contains siloxane units of formula R′SiO 3/2 (where R′ is a hydrogen atom or a univalent hydrocarbon that is free of aliphatic unsaturated carbon-carbon bonds) and/or siloxane units of formula SiO 4/2 , or any of components (A) and (B) contains said siloxane units.
