Abstract:
A method for fabricating bipolar junction transistor (BJT) includes the steps of: providing a substrate having an emitter region, a base region, and a collector region; performing a first implantation process to form a first well region in the base region; and performing a second implantation process to form a second well region in the emitter region. Preferably, the first well region and the second well region comprise different concentration.

Claim (Index 6):
The method of  claim 2 , further comprising:\n performing the second implantation process to form a first region in the fin-shaped structures on the emitter region and a second region under the first region; and performing an thermal treatment to diffuse dopants from the first region downward and dopants from the first well region into the second region to form the second well region.
