ABSTRACT:
A method for fabricating an indium antimonide semiconductor device which includes anodizing through a portion of the thickness of an indium antimonide substrate containing an active impurity of a first type; selectively ion implanting an active impurity of a second type into the indium antimonide substrate; annealing; providing for ohmic electrical contact between preselected regions of the indium antimonide substrate and subsequently applied electrical contacts; and depositing a plurality of electrical contacts, a predetermined number of which are in ohmic electrical contact with the preselected regions of the substrate to thereby provide the semiconductor device; and semiconductor device obtained thereby.
