Abstract
A T.F.T. has a polycrystalline semi-conductor layer with a thickness in excess of 10,000 and which is composed of crystallites with size greater than 5000 . Preferably, the thickness is about 250,000 and the crystallite size about 10,000 . Such a transistor may be formed by silk screening a semi-conductor slurry of suitable particle size on to an insulating support and sintering the layer thus formed. The electrodes may be applied by masked evaporation and the gate insulation by masked evaporation or sputtering or by silk screening. Suitable substrate materials are glass, ceramics, and fused quartz. Suitable semi-conductors are germanium, silicon, germanium-silicon alloys, zinc oxide, the sulphides, selenides and tellurides of zinc and cadmium, and the phosphides, arsenides and antimonides of aluminium, gallium and indium. The gate insulation (preferably less than 2Á thick) may be of silicon monoxide, silica, silicon nitride, calciumfluoride, alumina, or zinc sulphide. The source and drain electrodes (less than 100Á or, preferably, 1-20Á apart) may be of aluminium, indium, gold or copper and the gate electrode of aluminium or gold. The formation of cadmium sulphide is described and the preparation of slurries of cadmium sulphide and cadmium selenide.
