Abstract:
1. A semiconductor device characterized in that at least one semiconductor element is provided, the semiconductor elements and at least a part of electrical connecting portions for use in electrically connecting the semiconductor elements to external devices are covered with a synthetic high molecular weight compound, the synthetic high molecular weight compound is a cured product obtained by heat-curing a silicon-containing curable composition which contains silicon-containing polymers as components (A), (B), and (C) described below and a catalyst as component (D) described below, component (A) is a silicon-containing polymer which has one or more reactive groups (A′) selected from the group consisting of the formulas Si—R component (B) is a silicon-containing polymer which has Si—H groups and has bridged structures formed by Si—O—Si bonds at one location or more, wherein greater than 80 wt % of the molecules of component (B) have a molecular weight of greater than 1,000, component (C) is a silicon-containing polymer which has one or more reactive groups (A′) selected from the group consisting of the formulas Si—R component (D) is a curing catalyst which is a platinum catalyst.
