ABSTRACT:
A semiconductor device comprises a body of semiconductor material having a base-emitter structure on a first surface of the body. The base emitter structure includes a plurality of discrete emitter regions interdigitated with a base region having a base contact on the base region. A base contact ring is attached coaxially to the base contact. An improved base terminal structure comprises a conductive base feed-through ring having a base terminal integral with the feed-through ring. The base feed-through ring is spaced from and concentric with the base contact ring. The base terminal structure further includes a resilient contact ring attached to the base contact ring and the base feed-through ring to provide a low impedance interconnection between the base contact ring and the base feed-through ring.
