Abstract

1,192,169. Semi-conductor devices. MITSUBISHI DENKI K.K. 21 March, 1969 [22 March, 1968], No. 15028/69. Heading H1K. At least one of a pair of pressure plates 26, 28 between which one or more semi-conductor devices 10, 12 are supported under pressure comprises, in its unloaded state, Fig. 3, a segment of a sphere of a resilient material, e.g. spring steel. Pressure is applied between the plates 26, 28 at a number of peripheral points so as to increase the radius of curvature of the or each resilient plate 26, 28, preferably to infinity as shown in Fig. 1, thereby to exert pressure on the devices 10, 12. In the form shown the pressure is transmitted to the devices 10, 12 by heat sinks 14, 16, 18 which may be internally cooled by liquid or may carry cooling fins. The devices 10, 12 may be diodes, transistors or thyristors. Preferably both pressure plates 26, 28 are of the type shown in Fig. 3, but one may alternatively be rigid and flat.
