    摘要: A housing for high-power semiconductor components is disclosed. The housing consists of an insulator which forms the lateral boundary of the housing, a high-power semiconductor component which is bounded on either side by intermediate disks formed of tungsten or molybdenum, and outer disks formed of copper. The insulator and outer disks are connected by connecting members which may be coated with a protective layer and which surround a protective ring made of a high temperature material such as a ceramic or temperature resistant plastic. The tungsten or molybdenum intermediate disks have a higher total specific energy absorption capacity than does copper.

    摘要: A method for the production of a disk-shaped silicon semiconductor component with at least two adjoining zones of opposite type conductivity and different doping strengths using a lapping disk which includes the steps of positioning and semi-conductor component adjacent the lapping disk, subjecting the semiconductor disk to a suction pressure on its side opposite the lapping disk so as to be bowed up from an initial lapping plane with a radius of curvature corresponding to a desired angle, lapping the semiconductor disk with the rotating lapping disk and beveling off the bounding surface of the semiconductor disk opposite the plane of a pn-junction separating the two zones.
