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 10):
The method of  claim 9 , further comprising:\n forming an extrinsic base material layer of a doped semiconductor selected from the group consisting of doped polycrystalline silicon material, doped polycrystalline germanium and combinations thereof; forming a hard mask on the extrinsic base material layer; etching the extrinsic base material layer selective to the hard mask and the germanium containing layer to pattern an extrinsic base region; forming a spacer on the sidewalls of said extrinsic base region; and etching the germanium containing layer to pattern the base region with an etch that is selective to the hard mask and the spacer prior to said forming emitter and collector extension regions.
