Abstract

In semiconductor integrated circuit devices for vehicle use, an aluminum pad on a semiconductor chip and an external device are coupled to each other by wire bonding using a gold wire for the convenience of mounting. Such a semiconductor integrated circuit device, however, causes a connection failure due to the interaction between aluminum and gold in use for a long time at a relatively high temperature (about 150 degrees C.). A semiconductor integrated circuit device can include a semiconductor chip as a part of the device, an electrolytic gold plated surface film (gold-based metal plated film) provided over an aluminum-based bonding pad on a semiconductor chip via a barrier metal film, and a gold bonding wire (gold-based bonding wire) for interconnection between the plated surface film and an external lead provided over a wiring board (wiring substrate).
