Title: The Method of Alloying of Semiconductor or Metal Monocrystal and Semiconductor Device with application of this method
Inventor: ROIZIN NATAN MOISEEVICH
IPC: H01L21/24
Filed: 1967-12-15
Abstract: 1,173,810. Semi-conductor devices. N. M. ROIZIN, I. N. LARIONOV and A. G. KOLESOVA. 15 Dec., 1967, No. 57057/67. Heading H1K. [Also in Division C7] In a method of alloying a monocrystal of semiconductor material or metal in which the dopant is introduced from a melt moved along a surface of the crystal by passing an electric current through the crystal, the surface along which the melt is moved is parallel to a line of intersection of the planes of maximum packing of the crystal atoms and the current flow at the surface is parallel to said line. A P-type germanium plate having a (110) major face and with its longitudinal axis in the [110] direction is etched, and the ends are fitted with tantalum contact holders which rest on and are free to slide upon respective electrode members. A bead of gallium-antimony alloy is placed on the surface of the germanium plate near one electrode and the plate is heated in a dry hydrogen atmosphere while passing a current through the plate to produce an alloyed strip in the surface due to movement of the molten material. The alloyed strip is in the form of a straight trihedral prism two side faces of which coincide with the {111} planes. As shown, Fig. 4, a transistor is produced by etching the plate in a selective solution which removes layers of material parallel to the planes of maximum packing, the rate of etching of the highly doped alloyed region 7 being several times less than that of the remainder of the plate 1. The base region 8 is produced by diffusion of antimony from germanium powder alloyed with antimony in a hydrogen atmosphere, antimony simultaneously diffusing out of the alloyed strip 7 to form that part of the base region directly below the emitter. A metal layer 9 is applied by spraying in vacuo, the emitter strip 7 forming a mask for the base electrode. The plate may be divided into a plurality of shorter lengths. The transistor may be used as pressure-sensitive transducer.

Abstract: 1,197,220. Colour television tubes. SYLVANIA ELECTRIC PRODUCTS Inc. 18 Dec., 1967 [29 Dec., 1966], No. 57312/67. Heading H1D. [Also in Division G2] In the manufacture of a colour television screen by photographic exposure through the shadow mask 21, Fig. 4, used in the completed tube, the optical system includes a modified plano-concave lens 71 arranged so that the apparent source of light has a locus N-M for different parts of the screen which corresponds to the locus of the centre of deflection of the electron beam in the completed tube. The lens 71 shown in detail in Fig. 7 comprises a spherical face 89 and a plane face 93 which terminates at a chord 96 and merges into a cylindrical portion 97. The portion of the lens which is used is centred on the optical axis 72, so the crescent shaped portion 8 is not used and may be cut off. In a modification, Fig. 8 (not shown), the plane surface 93 terminates at its opposite edge at another parallel chord which merges into a second cylindrical portion of opposite curvature to that of the first cylindrical portion 97. The profile of the first cylindrical portion 97 along section lines 9-9 may be flat (Fig. 9, not shown), elliptical (Fig. 10, not shown) or hyperbolic (Fig. 11, not shown), and the profile of the second cylindrical portion, when provided, may be similar (Figs. 12-14, not shown). As shown in Fig. 4, the point source of light 69 is offset by a distance k from the axis 12 of the tube and the lens 71 is tilted by an angle # with respect to the axis. The lens is aligned with its axis of symmetry along the 10 o'clock-4 o'clock axis of the screen for the deposition of one colour phosphor, along the 2 o'clock-8 o'clock axis for the deposition of a second colour phosphor, and along the vertical axis for the deposition of the third colour phosphor, thereby producing the required corrections to the positions of the colour dots at the corners of a rectangular screen (Fig. 5 not shown).
