Patent number: 8791546Abstract: A bipolar transistor comprises at least first and second connected emitter-base (EB) junctions having, respectively, different first and second EB junction depths, and a buried layer (BL) collector having a greater third depth. The emitters and bases corresponding to the different EB junctions are provided during a chain implant.
