PURPOSE:To prevent a primary oxidized film from cracking at the bonding time by rounding the boundary between lead wirings led from the pad and the pad. CONSTITUTION:A pad 21 and the corners (c, d) of lead wirings 22 are bonded with suitable curvature. According to this configuration, an impact at the bonding time can be transmitted to thw wirings 22, a primary oxidized film is not cracked, a margin for the bonding load can be increased, thereby increasing the yield. |
