Abstract

902,318. Semi-conductor devices. SIEMENSSCHUCKERTWERKE A.G. Nov. 14, 1960 [Nov. 13, 1959], No. 39112/60. Class 37. In a method of producing a semi-conductor assembly, bearing surfaces of a semi-conductor device and a heat-conducting member are accurately matched by superfine working, at least one of the bearing surfaces is roughened and the device is detachably secured to the heatconducting member so that the bearing surfaces are in heat-conducting contact at many points distributed over the entire bearing surface of the device. As shown, a plurality of parallelconnected rectifier cells are mounted in two rows on a cooling block 2 which may be watercooled, or air-cooled, in which case it is provided with fins 12. Each cell comprises a housing 3 of Cu &c. having a base 3a of relatively large diameter and containing a Mo carrier plate 5 on which is mounted a Si wafer 4 comprising a PN junction. A flexible lead 7 from an electrode 6 on the upper surface of the wafer passes out of the housing 3 through a glass seal 8. The upper face of the block 2 and the lower face of the base 3a are ground to a superfine finish; then the latter face is roughly lapped and clamped to the upper face of the block 2 by means of clamping bars 10 of, e.g. hard spring steel, clamping rings 11, and bolts 9. Alternatively, the roughening of the bearing surface may be effected by sandblasting, and the roughened surface may be coated with a medium having good thermal conductivity, such as silicone oil.
