Abstract
929,240. Semi-conductor devices. MINISTER OF AVIATION. Feb. 29, 1956 [Nov. 30, 1954], No. 34731/54. Class 37. A photo-sensitive semi-conductor device of the PN junction type comprises a mass of semiconductor material with current carriers of low effective mass 1, in which the body of the mass is of P type conductivity and a surface layer 2 is of N type conductivity so that a rectifying (PN) junction is formed between them, connections being made to the body and the surface layer to define a current path across the junction between the connections, and the thickness of the surface layer being determined so that radiation incident upon the layer can pass through to the junction of the body with the surface layer. The device may be of InSb with the layer 2 of N type having Te or another Group VI element as impurity. By controlling the concentration of impurity, e.g. to provide 5 x 10<SP>19</SP> or 5 x 10<SP>16</SP> electrons per cc., the transmission cut-off wavelength of the surface layer is determined. The Te is included by coating P type InSb with Te and then diffusing it with heat to a depth of 5 to 10 thousandths of an inch. The semi-conductor material may alternatively be InAs.
