SILICONE ADHESIVE SHEET, ITS MANUFACTURE AND SEMICONDUCTOR DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a silicone adhesive sheet having excellent handling and working properties and excellent adhesion properties, a method for efficiently manufacturing such a silicone adhesive sheet, and a reliable semiconductor device mounting a semiconductor chip at a chip-attaching portion by means of the silicone adhesive sheet. SOLUTION: This silicone adhesive sheet comprises a crosslinkable silicone composition crosslinked between substrates having a release property against the crosslinked product of the composition. In a method for manufacturing the silicone adhesive sheet, at least one of the substrates has an oxygen atom and/or sulfur atom at the surface in contact with the composition, and a semiconductor device has a semiconductor chip mounted on a chip-attaching portion by means of the silicone adhesive sheet.
