Title: Improvements in semi-conductor devices
IPC: H01L21/00
Filed: 1953-11-17
Abstract: 779,146. Transistors. GENERAL ELECTRIC CO. Nov. 17, 1953 [Nov. 18, 1952], No. 31883/53. Class 37. A transistor is formed from a semi-conductor body with a region of one type conductivity sandwiched between two regions of opposite type by fusing a base connection in the form of a mass of an activator element of the type predominant in the middle region, to a surface of that zone and adjacent surface portions of the outer regions to make good conductive contact with the middle zone and to change the conductivity type of parts of the outer zones. A Ge wafer 31 (Fig. 3) with thin P-type zones 36, 37, 38 between N-type zones 32, 33, 34, 35 has in conducting contact with the N-zones on one face large area film electrodes 39-42 of neutral or preferably donor material such as Sb, which are alternately connected together and a layer of acceptor, such as indium connected to plate 46 in contact with the entire opposite face, the assembly being heated to fuse and to diffuse the In into the wafer as before. In a further arrangement (Fig. 4), a thin Ge wafer 54 has a single P-type zone between N-type zones, connection to the latter being made through layers of solder 58, 59 of e.g. Sb, the upper one 58 having spaced holes 62. Concentric but smaller holes 63 which are drilled to extend through N-type zone 56 and the P-type zone 55 into N-type zone 57 are partly filled with In 64 which is fused to and diffused into the adjacent regions, the In electrodes being joined by wires 65. Alternatively, the N-P-N wafer may be made by starting with a P-type body which is heated in contact with its Sb electrodes so that the latter diffuse into it to form the junctions. Multi-junction wafers for such transistors may also be prepared by seed crystal withdrawal from a melt containng acceptor and donor impurities in quantities which yield intrinsic material at a certain growth rate. The impurities are chosen to have different rates of segregation constant variation with growth rate in the region of the intrinsic growth rate so that by cyclic variation of temperature alternate zones of P and N-type may be grown.  Reference has been directed by the Comptroller to Specification 738,231.
