Filed: 1980-12-26
Abstract: PURPOSE:To obtain stable bonding strength from the same ponding condition by forming a P type electrode and an N type electrode so as to make it possible to bond fine metallic wires to the same or substantially the same metallic layers. CONSTITUTION:Metallic electrode layers are formed on exposed surfaces of a P type and N type of a main surfaces. An end of a fine metallic wire is bonded to the metallic layer. In doing this, the first metallic electrode layer Au-Zn is formed on one conductive type surface and the first metallic electrode layer Au- Si, different from the metallic layer Au-Zn, is formed on the other conductive surface. The third metallic electrode layer Au-Zn, the same as the metallic electrode Au-Zn formed on the other conductive surface, is formed through the second metallic electrode layer Au. A stable bonding strength is thus obtained by bonding under the same condition.
