Abstract
A semiconductor device has a semiconductor region, an electrode layer formed over the semiconductor region, and a protection layer formed to cover the semiconductor region and the electrode layer. In the semiconductor device, the protection layer is a semiconductor protection layer. Part of the semiconductive protection layer is formed thin so as to have a low resistance, permitting a corresponding portion of the electrode layer to be connected to an external bonding wire.
