Abstract:
1. A semiconductor device, comprising: a semiconductor substrate; a first discontinuous subcollector, wherein the first discontinuous subcollector comprises a first doped region and a second doped region separated by a first space; a second discontinuous subcollector on top of the first discontinuous subcollector, wherein the second discontinuous subcollector comprises a first doped region and a second doped region separated by a second space; a single continuous collector formed over the first and second discontinuous subcollectors and within at least the second space of the second discontinuous subcollector; and a base structure and an emitter structure over the second space separating the first and second doped regions of the second discontinuous subcollector, wherein at least part of the collector separates the base structure from the second discontinuous subcollector.
