Abstract

1373960 Field-effect transistors TEXAS INSTRUMENTS Ltd 7 Dec 1971 56750/71 Heading H1K The Figure shows a plan view of a field-effect transistor having source 1, drain 2, and gate 3 electrodes, the gate electrode being of small width, defining a closed figure, and extending over all its length in directions making no more than a small angle {tan<SP>-1</SP>(¢)} to a given (x) direction. The gate may instead follow the outline of a parallelogram or of a double convex lens. In the embodiment shown the source and drain electrodes contact enhanced conductivity regions 8, 9 of an N type epitaxial layer grown on a P type silicon substrate. The gate electrode is of aluminium and may form an alloy junction or a Schottky barrier. Similar gate arrangements may be provided for IGFETs, and any of the devices may be incorporated in integrated circuits.
