A method of forming a quasi-self-aligned heterojunction bipolar transistor (HBT) that exhibits high-performance is provided. The method includes the use of a patterned emitter landing pad stack which serves to improve the alignment for the emitter-opening lithography and as an etch stop layer for the emitter opening etch. The present invention also provides an HBT that includes a raised extrinsic base having monocrystalline regions located beneath the emitter landing pad stack.
