Abstract

1,048,740. Semi-conductor devices. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Oct. 28, 1965 [Nov. 30, 1964], No. 48509/64. Heading H1K. In a semi-conductor device comprising a plurality of junctions in a semi-conductor wafer having major and minor opposed faces and a single peripheral face inclined at other than 90 degrees to the two opposed faces, the resistivity of the material adjacent the minor face of each PN junction is higher than that on the other side. The peripheral face may be linear or curved and preferably set at less than 60 degrees to the major face. The device may be rectangular, circular or oval in plan and may be of silicon or germanium. In the embodiment, the resistivities of the P, N and P<SP>+</SP> layers are 100, 50 and 0À5 ohm/cm, respectively.
