Abstract
The specification describes a metal contact material optimized for diffused contacts to the buried emitter-base junction in DHBT devices. The metal contact material is a multilayer structure of Pd-Pt-Au which gives the required critical diffusion properties for low resistance contacts to the buried base layer without shorting to the collector layer.
