<p>PURPOSE:To increase adhesion on the interface between a frame and a resin by forming a fine ceramics coating film onto the surface of a metallic member. CONSTITUTION:A fine ceramics coating film 11 is shaped onto the whole surface of the surface and rear of a frame 11 through a method such as a CVD method as shown in an oblique line, and an integrated circuit element 3 is bonded with a die pad 4. The integrated circuit element 3 and leads 5 are connected by gold wires 6, and these gold wires, integrated circuit element and leads are sealed with a resin. Single oxide group alumina, the composite oxide of silicon oxide and alumina or the silicon nitride of non-oxide group ceramics is used as the fine ceramics coating film at that time. Accordingly, bonding power between the frame 1 and the resin is increased by the formation, etc. of firm hydrogen bonds between the fine ceramics coating film 11 being shaped and the resin.</p> |
