Abstract
1372610 Semi-conductor devices INTER. NATIONAL BUSINESS MACHINES CORP 21 Nov 1972 [10 Dec 1971] 53667/72 Heading H1K A FET comprises a substrate 1 of Cr doped semi-insulant GaAs produced from a sliced and polished crystal which is infra-red heated in an open tube reactor in a circulating H 2 atmosphere, to which AsCl 3 is added; the gas flowing over a boat containing Ga saturated with As, the substrate being cut parallel to the 111 crystal plane and coated on the side exhibiting more Ga atoms at the surface. An undoped buffer layer is epitaxially deposited thereon, into which physical defects of the interface plane of substrate 1 extend. Therefore, a further highly conductive layer 8 doped with sulphur from H 2 S is epitaxially deposited to suppress the imperfections and provide a channel layer on which ohmic source drain contacts 3, 5 and Schottky gate control 4 are conventionally deposited.
