Abstract
1327204 Semi-conductor devices ASSOCIATED ELECTRICAL INDUSTRIES Ltd 24 Jan 1972 [17 Feb 1971] 4828/71 Heading H1K A thyristor comprises (Fig. 1) a Si semi-conductor body 1 having PNP-layers 2, 3, 4 of alternate conductivity types; N-layer 5 extending from the outer face into P-layer 2. Conducting electrode layers 6, 7 are formed on the respective outer faces of layers 5, 4 and layer 6 also overlaps the exposed surface of layer 2 surrounding layer 5; while conducting layer 8 constitutes a trigger and contacts layer 2. Gold is introduced into layer 3 as a lifetime reducing impurity for minority carriers in restricted regions 9 also extending through layer 4; so as to improve recovery. In manufacture (Figs. 2, 3) the body containing layers 2, 3, 4, 5 and before deposition of layers 6, 7, 8 is strongly heating in nitrogen in a quartz furnace tube; and oxygen is introduced after bubbling through phosphorus oxychloride; to deposit a vitreous surface layer 10 of phosphorus silicate. Further heating in absence of oxygen forms an underlying phosphorus doped silicon layer 11. Slow cooling getters fast diffusing impurities by trapping in layers 10, 11, which are selectively removed by wax masking and etching first in HF and then in HNO 3 + HF. After removal of wax and washing, a layer 12 of Au is deposited (Fig. 3) by immersion in dilute chlorauric acid. Thereafter, heating in N 2 diffuses Au through gaps 13 to form regions 9, and the gettering layer 10, 11 inhibits deposition of Au except in the gaps. Layers 10, 11 and corresponding Au layers are etched off and electrode layers 6, 5 are deposited. Layers 10, 11 may be formed by using O 2 mixed with gaseous phosphines or P 2 O 5 vapour. The process is applicable to other semi-conductor devices.
