Abstract

985,450. Semi-conductor devices. SIEMENS-SCHUCKERTWERKE A.G. April 24, 1962 [April 22, 1961], No. 15644/62. Heading H1K. A semi-conductor body having a PN junction between planar faces with an impurity concentration gradient between the junction and one face and electrodes on the faces is subjected to etching or mechanical treatment to remove some of the semi-conductor material to increase the distance along the surface between the limits of the space charge region around the junction. This reduces the field strength and lessens the tendency to breakdown. Fig. 1 shows a semiconductor body 1 with PN junction 4 and electrodes 5 and 6. Material is removed to provide a new surface provided by generatrix line 11. Line 11 may be curved convex or concave or both. Fig. 8 shows an etching jet 23 arranged for controlled removal of material from semiconductor body 22 which is mounted on a turntable. Chemical or electro-chemical etching may be employed. Silicon, germanium and A 3 B 5 compounds are referred to and the PN junction may be provided by diffusion from both sides, or diffusion from one and alloying from the other.
