Abstract : A process for forming low resistance ohmic contacts on indium phosphide (InP) avoids the usual problem of high temperature annealing. The method comprises passing a current between two contacts of a suitably chosen metallic conductor that is doped so as to be the same conductivity type as the underlining semiconductor. Passage of the current causes the contacts to combine with the semiconductor via field assisted thermal diffusion.
