Claim:
1. A method of manufacturing a silicone composition for sealing a semiconductor comprising: a step of subjecting a first organosiloxane represented by an average unit formula: (R a step of mixing or compounding 100 parts by weight of the polyorganosiloxane (A), an amount of a polyorganohydrogensiloxane (B) having two or more hydrogen atoms bonded to silicone atoms per molecule and having a viscosity at 25° C. of 1 to 100 mPa·s so that an amount of the hydrogen atoms bonded to the silcon atoms is 0.5 to 3.0 mol per mol of the alkenyl groups bonded to silicon atoms in the (A) component, and a catalyst amount of a platinum-based catalyst (C).
