Abstract
An electronic semiconductor device comprising a semiconductor base deposited on a semiconductor substrate by means of molecular beam epitaxy and source, drain and gate disposed on the base in a spaced relationghip to each other, the source and the drain comprising Pd/barrier/Au layers with the palladium layer being in contact with the device. The device is fabricated conventionally except the heat treating is at above about 170° C. for ¼-10 hours sufficient for the palladium layer to react with the base yielding reduced contact and access resistances and a narrower spacing between source and drain.
