Abstract
Structures that include bipolar junction transistors and methods of forming such structures. The structure comprises a substrate having a top surface, a trench isolation region in the substrate, and a base layer on the top surface of the substrate. The base layer extending across the trench isolation region. A first bipolar junction transistor includes a first collector in the substrate and a first emitter on a first portion of the first base layer. The first portion of the first base layer is positioned between the first collector and the first emitter. A second bipolar junction transistor includes a second collector in the substrate and a second emitter on a second portion of the first base layer. The second portion of the first base layer is positioned between the second collector and the second emitter.
