Abstract:
A method of forming a lateral bipolar junction transistor (LBJT) that includes providing a germanium containing layer on a crystalline oxide layer, and patterning the germanium containing layer stopping on the crystalline oxide layer to form a base region. The method may further include forming emitter and collector extension regions on opposing sides of the base region using ion implantation, and epitaxially forming an emitter region and collector region on the crystalline oxide layer into contact with the emitter and collector extension regions. The crystalline oxide layer provides a seed layer for the epitaxial formation of the emitter and collector regions.

Claim (Index 17):
A method of forming a lateral bipolar junction transistor (LBJT) comprising:\n forming an extrinsic base region on a material stack including a germanium containing layer; forming a spacer on the sidewalls of the extrinsic base region; etching the germanium containing layer using the extrinsic base region and said spacer as a mask with an etch to form a base region that is overlying an underlying crystalline oxide layer that is a portion of the material stack including the germanium containing layer; forming emitter and collector extension regions on opposing sides of the base region; and forming an emitter region and collector region on the crystalline oxide layer.
