Title: A kind of double heterojunction bipolar transistor structure with wide operating range for working point voltage
Inventor: LIOU WEN-CHAU
IPC: H01L29/737
Filed: 1998-12-04
Granted: 2000-03-01
Abstract: A kind of double heterojunction bipolar transistor structure with wide operating range for working voltage which is a novel, high speed, low power consumption and high breakdown voltage of microwave power transistor and as an improved InGaP/GaAs double heterojunction bipolar transistor with a very wide operating range of collector-emitter working point voltage. The feature is to include the In0.49Ga0.51P collector layer, GaAs delta-doping sheet and undoped GaAs spacer in the collector area. Because at the effective base-collector heterojunction has introduced a spacer and a layer of delta-doping sheet so the barrier peak will not appear at the base-collector heterojunction and effectively avoid the electron blocking effect. In the emitter area, the invention has designed to comprise the five period In0.49Ga0.51P/GaAs superlatticed confinement layer and GaAs emitter homojunction and employ the superlatticed confinement layer as the confinement barrier for few carriers ( electric holes) and the base-emitter homojunction is used to control most carriers (electrons) injected into base from emitter. Therefore, the method can achieve both characteristics of high emitter injection efficiency and low offset voltage. The invented component is very suitable to be used in digital and analog circuits of high speed, low power consumption and high breakdown voltage.

Title: Process for lowering metal contact resistance and the transistor metal contact formed by the said method
Inventor: LIAU CHUNG-WEI
IPC: H01L21/768
Filed: 1998-12-31
Granted: 2000-10-21
Abstract: A metal contact process for lowering the contact resistance is disclosed, which is to implant the ions on the surface of the ready-to-form metal contact region to increase the surface doping concentration, to remove part of this region to expose the sidewall, so that the subsequent metal layer contacts the surface region of its high doping concentration and the sidewall at the same time. The metal contact utilizing said method to form the transistor comprising the region with reverse electrical-conductive style on the surface of high doping concentration, one of them exposes the sidewall; meanwhile, a metal layer is in contact with the surface of high doping concentration and the sidewall of said region. The metal contact process disclosed by this invention dopes on the surface of the ready-to-form metal contact region; and then, remove part of said region so that the contact resistor between the metal and the silicon could be lowered without adding extra mask. The formed metal contact bottom has steps, and the contact area between the metal and the silicon is increased due to the contact between the metal layer and the sidewall; further, it lowers the contact resistance.
