  • Method for the manufacture of the extrinsic base of an NPN transistor in a high-frequency bipolar technology
    Patent number: 5981348
    Abstract: Disclosed is a method for the fabrication of an extrinsic base of an NPN transistor using high frequency bipolar technology. According to the method, using a doping of the extrinsic base of the transistor by ion implantation, the amorphous crystal lattice is recrystallized by very high-speed thermal annealing before the dopants of the extrinsic base are diffused in the epitaxial layer.
