Abstract

PURPOSE:To provide a semiconductor device which has large bonding strength and a high reliability by conducting a ball bonding in advance on an aluminum surface and stitch bonding on the ball bond. CONSTITUTION:A ball bond 3 is formed in advance on an aluminum 2 at predetermined position for the second bonding. Then, a ball bond 4 is formed on an aluminum surface 1 at predetermined position for the first bonding, and a stitch bond 5 is formed on the first ball bond 3. Thus, both the aluminum surfaces 1 and 2 become equal to the ball bond by the bonding wire, and slight Au-Al intermetallic compound is produced at both the bonds. Accordingly, it can increase the bonding strength at the second bonding portion.
