Abstract: 1309346 Thin film transistors R R HAERING and J F O'HANLON 19 April 1971 [27 April 1970] 10001/71 Heading H1K An insulated gate thin film transistor has a gate insulation comprising two layers having an enhancing and a depleting effect respectively on the concentration of majority carriers at the surface of the semi-conductor layer and has a layer with a depleting effect on the side of the semi-conductor layer opposite the gate. The n-type transistor described, for use at sourcedrain voltages of up to 400 volts, has a sourcedrain gap of 0À025 cm. and a total gate insulation thickness of approximately 10,000 Š. Typically the device is formed by deposition on a glass substrate with the gate uppermost or lowermost. A suitable semi-conductor material is hexagonal cadmium sulphide deposited under such conditions as to form crystallites of 300-700 Š diameter with their C-axes normal to the layer. In a second example cadmium selenide is used. Calcium fluoride and silicon oxide are suitable depletion and enhancement materials respectively, their thickness in the composite layer preferably being selected so that the surface and bulk potentials of the semi-conductor body are equal, to minimize the offset voltage. In a typical example a further layer of vapour deposited germanium dioxide is located between the composite layer and the gate metallization. Details of the deposition processes are given. Reference has been directed by the Comptroller to Specification 1,229,330.
