Abstract
1295422 Semi-conductor devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 10 Feb 1970 [13 Feb 1969] 6361/70 Heading H1K A thyristor is formed in the following manner; a P-type silicon substrate 1, Fig. 7, has arsenic deposited on one surface to form a region 3, and further depositions of boron to form zones 4; a phosphorus-doped N-type epitaxial layer 5 is formed on the surface, and boron deposited on its surface to form zones 6 and 7; a second N- type epitaxial layer 8 is deposited on layer 5, and boron doped zones 9, 10 formed in its surface; the depositions are then » driven in » so that zones 4, 7, 10 combine to form isolation zones 12, and zone 9 contacts the » buried » zone 6; a P-type zone 11 is diffused into the surface of the layer 8, and an N-type zone 15 formed within the zone 11; electrodes 17, 20 and 21 contact the anode, 9, 6, the gate zone 11, and the cathode 15 respectively. The » buried » region 3 prevents a parasitic transistor forming from the substrate 1, layer 5 and zone 6. The thyristor may be incorporated in an integrated circuit, e.g. to form part of an oscillator. Gold doping may be used to improve the switching rate. The » buried » zone 6 may alternatively be formed by ion implantation.
