Siloxanmodifizierte Poyamidharzzusammensetzung, Klebefilme, Klebefolie, und Halbleiterbauelement

摘要

An adhesive sheet comprises a polyimide base layer and an adhesive layer (a) disposed on at least one side of the polyimide base layer, the adhesive layer (a) being a layer of a B-stage cured product of a siloxane-modified polyamideimide resin composition comprising 100 parts by weight of a siloxane-modified polyamideimide resin and 1 to 200 parts by weight of a thermosetting resin ingredient. A chip-size package board is produced by making a through-hole in the adhesive sheet, laminating a copper foil on the adhesive layer (a), forming a circuit by removing unnecessary parts of the copper foil by etching, and then gold plating a surface of the circuit. A semiconductor device is prepared by bonding a semiconductor chip to the surface of the chip-size package board bearing the circuit, connecting the circuit of the chip-size package board to bonding pads of the semiconductor chip, and sealing the circuit of the chip-size package board, the bonding wires and the semiconductor chip with a molded resin.
