Title: A controllable electric symmetrically conductive system
IPC: H01L27/082
Filed: 1953-07-29
Abstract: 741,193. Semi-conductor devices. LICENTIA PATENT-VERWALTUNGS-GES. July 29, 1953 [July 29, 1952; July 29, 1952], No. 21029/53. Class 37. A multi-electrode semi-conductive device comprises a semi-conductor body of one type of conductivity provided with a region of opposite conductivity on one face associated with a main electrode, the semi-conductor body having one primary carrier electrode, and two or more additional control electrodes located nearer the region of opposite conductivity than the primary carrier electrode. As shown (Fig. 1) a semiconductor body 1 with a carrier electrode 2 has a region 3 of opposite type of conductivity with its main electrode 5, and two additional control electrodes 6, 9 located near the borders of the converted region 3. The carrier electrode 2 may be rectangular, located directly opposite the converted region 3, or a ring located along the edge of the underside of the body 1, or round the side faces of the body 1, with an additional control electrode opposite the converted region 3. The characteristics of the barrier layer between electrodes 2 and 5 may be varied by causing small currents to flow from control electrodes 6, 9 to the body 1. In another embodiment (Fig. 5) the semi-conductor body 12 with a carrier electrode 13 has two converted regions 15, 16, each with its main electrode 17, 18 respectively, separated by a distance of the same order as the depth of the layers of opposite conductivity under regions 15, 16. Auxiliary electrodes may be added, preferably symmetrically, as shown at 24, 25, 26, 27 (Fig. 6). The electrodes 24, 25 may be used to control currents flowing through both converted regions, or electrodes 26, 27 may be used to control each region independently. Auxiliary electrodes may alternatively be located on the side faces of the body 12. The devices described may be used in photo-electrically controllable electric asymmetrically conductive systems, in which case the carrier electrode 2 (Fig. 1) or 13 (Fig. 5) is in the form of a net or grid. The conversion in the restricted regions from one type of conductivity to the other may be effected by local short time electric heating as by a current impulse from a small electrode, produced, e.g., by a condenser discharge, or by an arc, preferably in an atmosphere of hydrogen or helium. The conversion may alternatively be effected by subjecting the surface to a charge-carrier beam, e.g. an electron beam. The conductivity of the converted region may be tested with two tungsten-pointed probes. When the probes are a short distance apart on the surface, the resistance between them is smaller and ohmic when the body has P-type conductivity, and larger and non-ohmic when the body has N-type conductivity.
