Abstract

873,916. Semi-conductor devices. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 3, 1959 [July 23, 1958], No. 23724/58. Class 37. The envelope of a semiconductor device, e.g. a junction diode or transistor, is filled with a pasty composition comprising a powdered electrically insulating hygroscopic solid of good thermal conductivity and an insulating fluid, e.g. a silicone grease. Calcium aluminium silicate and sodium aluminium silicates are suitable hygroscopic materials. The composition may also include powdered silicon, alumina or magnesia to improve its heat conductivity. The components of the composition are dried separately before mixing to form a filling paste which is introduced into the envelope by a grease gun. In one embodiment (Fig. 2) a cap-shaped cover member 12 is filled with the paste and a base member 8, through which the leads to transistor 9 pass, is subsequently resistance welded to an annular ridge on the flange of the cover member.
