ABSTRACT:
An electronic power device of improved structure is fabricated with MOS technology to have a gate finger region and corresponding source regions on either sides of the gate region. This device has a first-level metal layer arranged to independently contact the gate region and source regions, and has a protective passivation layer arranged to cover the gate region. Advantageously, a wettable metal layer, deposited onto the passivation layer and the first-level metal layer, overlies said source regions. In this way, the additional wettable metal layer is made to act as a second-level metal.
