Abstract
The boron out-diffusion into the Si collector of SiGe HBT's with implanted emitters is compensated by an epitaxially grown n+ phosphorus peak effectively positioned adjacent to the as-grown boron peak. Detrimental barrier formation is suppressed in devices with base sheet resistance 3.3 kΩ and cut-off frequency of 31 GHz.
