Abstract
An integrated circuit includes a bipolar transistor disposed over a substrate. The bipolar transistor includes a base electrode disposed around at least one germanium-containing layer. An emitter electrode is disposed over the at least one germanium-containing layer. At least one isolation structure is disposed between the emitter electrode and the at least one germanium-containing layer. A top surface of the at least one isolation structure is disposed between and electrically isolating a top surface of the emitter electrode from a top surface of the at least one germanium-containing layer.
