Title: Improvements in or relating to semi-conductor devices and methods of manufacturing these devices
IPC: H01L29/00
Filed: 1960-04-01
Abstract: 926,280. Semi-conductor devices. SIEMENS & HALSKE A.G. April 1, 1960 [April 3, 1959], No. 11598/60. Addition to 849,447. Class 37. A semi-conductor device comprises a plurality of electrodes produced by alloying wires to one surface of a semi-conductor crystal housing a layer of one type of conductivity on a body of the opposite type, the wires being coated with different materials and having substantial parts of their lengths in contact with the surface. In the Figure, wires 5 and 6, which may be 10Á diameter, are pressed against the surface of a P-type germanium body having a 1-5Á thick N-type layer 1 produced by diffusion of arsenic or antimony. Pressure may be provided by the weight of a frame upon which the wires are wound as described in the parent Specification, or by a punch or by the pressure of graphite powder. Wire 6 is coated with a donor impurity such as aluminium and wire 5 with both donor and acceptor material, such as aluminium and antimony. Alloying at 600‹ to 800‹ C. followed by a diffusion step at a temperature 10 to 50 degrees lower is then performed to provide an ohmic contact for wire 6 with an N+ layer 3 between the wire and N-type layer 1<SP>11</SP> and a rectifying contact for wire 5 due to the production of a P-type layer 2 between the wire and N-type layer 1<SP>11</SP>. In the process, the arsenic diffuses more quickly than the aluminium to provide the N-type region 1<SP>1</SP> while the aluminium forms the P-type layer 2. Wire 6 forms the base electrode, wire 5 the emitter, and the collector is connected ohmically to the underside of body 4. The N-type base zone comprising layer 1 and region 3 has a varying concentration of impurity centres to provide a drift type transistor. An etching process is then applied to produce the " plateau " shape of the body shown in the drawing. Silicon can be used in place of germanium, the alloying temperature then being 1000‹ to 1300‹ C. The distance between P-type zone 2 and N+ type zone 3 is made greater than the total thickness of the N-type layers 1<SP>1</SP> and 1<SP>11</SP>. The N-type diffused layer on body 4 may be produced simultaneously or after the wire alloying process. The wires may consist of W, Mo or Ta and coated electrolytically or by drawing through a droplet. The coating material may comprise a carrier material of Au, Ag, Bi or Pb or a Au-Pt alloy with an impurity consisting of B, Al, Ga or In or As or Sb.

Strips 84 pass between the abutting flanges of the channels 78, 83, &c. and form connecting means for the channels 83 on each side of the posts 59 and also for connecting gussets, panelling, &c. The curved panelling 45 below the belt rail is welded together and to angle irons attached to the posts. The roof carlines 63 comprise curved channel sectioned members welded together and form, with the side posts 59 and bottom channels 64, a closed frame. The bottom channels 64 and floor beam 69 are connected by diagonal struts 70, 71 and vertical struts 72, the latter being welded to continuous longitudinal beams 111, 112 which form the principal mid-section tension members of the car. The floor stringers 109 are also tension members and are welded to the floor beams 69 and are covered by flooring 110. The framework in the neighbourhood of the door is strengthened by longitudinal beams 119, 120, Fig. 9, diagonally braced and supported transversely by floor gusset plates 122-124 welded to the floor beams 69 and stringers 109, 111, the length of these gussets increasing from the longitudinal centre of the car to the side frames. The side posts are more closely spaced and additional roof carlines are positioned over the doorway and window openings. Transverse bulkheads 118 on each side of the doorway extend to the floor beams 69 or bottom beams 64. Roof plating 129 may also be positioned under the corrugated roof sheathing 58 and longitudinal plates are secured to the framing above the top rail.

Inertia governors; transmitting-mechanism.- In a marine governor of the kind in which a pendulum directly closes one of two circuits of a reversible electric motor actuating the engine stop-valve, the circuit is opened by the movement of the valve. The circuit, Fig. 7, includes two switches 23, 26 one of which is closed while the other is open. The current supply is connected to the pendulum contacts 58, 59 which touch fixed contacts 50, 51 to complete a circuit through the motor 17 and switch 23. The motor drives the shaft 3, Fig. 3, through worm-gear 18 until the cam 27 is moved clear of the switch-button 23, another cam (not shown) meanwhile engaging the switch-button 26. When the pendulum touches the contacts 52, 53, a reverse circuit is completed through the motor 17 and switch 26. The valve-actuating lever 2 is detachably secured to an arm 11 of the shaft 3. A hand-wheel 19 may operate the valve. An alternative circuit is described in which the pendulum is connected to the motor terminals and the source of current to the contacts 51, 53. Devices for adjusting the length of the pendulum and the distance between the fixed contacts are described.
