Abstract

1,157,041. Semi-conductor devices. INTERNATIONAL RECTIFIER CORP. 20 March, 1967 [29 April, 1966], No. 12984/67. Heading H1K. A semi-conductor device, consists of a wafer 11 containing a PN junction and sandwiched between expansion plates 12, 13, e.g. of molybdenum, of which the former is preferably smaller and the latter larger than the wafer, and is held between a housing base 10 forming one terminal and a stud 15 forming another by means of a spring constituted by one or more dished washers 24-26. The washer or washers act between the housing and an annular shoulder 16 on the stud 15. The spring tension depends on the distance between the base and top of the housing and this is adjusted in assembly by inserting shims 43, 44 before welding the body 41 of the housing to its base 10. The housing is assembled by first placing the spring washers in a cup-shaped insulator 40 and fitting this on the stud 15. The housing body 41 is then placed over the stud 15 and the shims 43, 44 are inserted between the body and the base of the housing. The number of shims is adjusted to attain the requisite spring pressure and a weld is then effected between the members 10 and 41.
