Abstract
715,398. Semi-conductive devices. GENERAL ELECTRIC CO., Ltd., DOUGLAS, R. W., and RYDE, J. W. Dec. 12, 1952, [Dec. 31, 1951.] No. 30488/51. Class 37. A semi-conductive amplifying device of the type comprising two blocks of material 1, 2 (Fig. 3) of arc conductivity type separated by material 3, 4 of the opposite conductivity type is manufactured by forming on the surface of one of the blocks a layer 3 of the opposite conductivity material bringing the two blocks into contact and heating them in an inert atmosphere while pressed together. The blocks i, 2 are of N-type germanium and the P-type layer is formed on the end of arc of the blocks by introducing a P-type impurity such as boron into the appropriate surface. Such a P-type layer may be formed on both blocks as shown-the drawings. Connections are made to blocks 1, 2 and the P-type layer by means of metal coatings 10, 11, 5 on the imposed surface. The coating may be made by plating, evaporation of metal or painting with metal paint. The completed amplifier may be embedded in a plastic housing.
