Fabrication technique for high performance semiconductor devices |
| abstract |
Microwave and pico-second switching transistors are fabricated by a process which includes (1) selective in-diffusion combined with selective out-diffusion to form three resistance levels in the base region; (2) composite diffusion masking for selfalignment of the base contact and emitter locations; and (3) the use of an arsenic-doped oxide diffusion source for the formation of emitter regions prior to doping the base contact locations. |
