Abstract
A semiconductor device includes a semiconductor substrate, an electrode disposed on an upper surface of the substrate, and a set of one or more transistor element(s) disposed on the upper surface of the substrate. The set of transistor element(s) compactly surrounds the electrode with a threshold distance. In one embodiment, the set also compactly surrounds a via hole. In another, the element(s) comprises a bipolar junction transistor that has an aggregate emitter length of not less than 10 microns. In still another embodiment, the device is coupled to a RF circuit for power amplification.
