Abstract

1,224,335. Semi-conductor devices. NORTH AMERICAN ROCKWELL CORP. 18 Sept., 1968 [28 Nov., 1967], No. 44418/68. Heading HlK. In an FET having N type source and drain regions the source and channel are separated by a P type isolation region. The P type reigon reduces the current which normally flows with zero gate bias. As shown, Fig. 1 an N channel enhancement mode IGFET is produced in a high resistivity P type silicon substrate 12 by forming a silicon dioxide layer 16 photomasking and exposing source and drain region sites, covering the drain site and diffusing boron into the source site to form P+ type isolation region 30 and then forming N+ type source and drain regions 18, 20 by diffusion. Aluminium is vapour deposited through a mask to form source, drain and gate electrodes 22, 24, 28. In a second embodiment, Fig. 5 (not shown) a thin P type semi-conductor layer (50) is epitaxially deposited on a single crystal insulating substrate (42), a central strip is masked with oxide (54), a P+ type zone (52) is formed extending beneath the oxide at one side and N+ type source and drain regions are produced by diffusion. The P+ type zone (52) separates the source from the channel. The semi-conductor material may be silicon, germanium or gallium arsenide, and the insulating substrate may be of sapphire, magnesium oxide, beryllium oxide or spinel. In a second modification, Fig. 7 (not shown), the P<SP>+</SP> type region is extended laterally and is provided with an electrode by means of which this region may be biased. The device can operate in both the depletion and the enhancement modes.
