Abstract
A first metal film made of a Cu plated film is formed on a radiation substrate A made of Al, and an island exposed from a back surface of a semiconductor device is adhered thereto. At that time, the back surface of the semiconductor device is brought into contact with contact areas, and a first opening portion OP is opened larger than an arranging area of the semiconductor device . Accordingly, the cleaning can be executed via the first opening portion OP exposed from peripheries of the semiconductor device . In addition, the heat generated from semiconductor elements can be radiated excellently from the island via a second supporting member A.
