Title: A semiconductor device
IPC: H01L29/00
Filed: 1961-07-28
Abstract: 985,864. Semi-conductor devices. TELEFUNKEN PATENTVERWERTUNGSG.m.b.H. July 28, 1961 [Aug. 5, 1960], No. 27454/61. Heading H1K. In PNIP or NPIN semi-conductor devices the thickness of the high resistance or intrinsically conductive zone between the emitting portion of the base zone and the collector zone is either less than or greater than this thickness between the collector zone and the remaining portion of the base zone. With the transistor shown in Fig. 1 the emitter 5 is formed in a Mesa portion of the intrinsic or high resistance layer 3 with an intervening base zone 1 having a base terminal B. The collector zone 2 has a terminal C. With the tetrode shown in Fig. 3 an auxiliary base electrode 8 forms an annulus about the control base electrode 4 with an intervening annular emitter zone 5 and base zone 1. Emission is confined to the annular region 7 where the thickness of the high resistance or intrinsic layer 3 is least. In a first method of producing the body from which the transistor or tetrode may be made, a heavily doped germanium wafer has a lightly doped layer deposited on one face by means of the thermal decomposition of a semi-conductor halide. In a second method a wafer of a kind to provide the high resistance or intrinsic layer is alloyed with an electrode over one face and to a depth such that the recrystallized semi-conductor layer will form the collector zone. In the particular case of the tetrode of Fig. 3 a germanium disc is first alloyed with indium to produce an annular region penetrating one surface. On to this surface a thin layer of indium is placed with a second germanium disc pressed on top. The assembly is then heated with the second disc at the higher temperature so that it becomes wholly P-type while the original disc is only partially affected to produce the junction between the collector zone and intrinsic zone shown in Fig. 3. To obtain the required thickness of intrinsic zone with a body produced by any of the above methods a self-limiting electrolytic etching process may be employed in which a barrier layer is set up in the body of a thickness corresponding to that required. Etching, which is provoked by repeatedly scanning a slit of light across the surface of the body, is automatically inhibited when the barrier layer is reached. The deeper penetrations are etched first with the smallest barrier layer and successive shallower penetrations are made subsequently with correspondingly increased barrier layers. With the tetrode of Fig. 3 etching may be pursued until the alloyed regions 7 begin to show through the surface of the intrinsic zone 3, a base zone being formed by diffusion and an emitter by alloying aluminium strips.

Bolts and screws.-In a modification of the device described in the parent Specification for automatically feeding screws &c. to a slotting saw, the blanks are lifted from loose assemblage in a hopper 1 by a slide 23, and are transferred to an inclined shoot 30 from which they are removed by a conveying member 38 and brought into contact with a guide 43 and a saw 44, the slide 23 and the member 38 moving along rectilinear paths as controlled by cams 24, 42 respectively. The cams act through linkages 26, 49 respectively and are opposed by springs 28, 48. The blanks are guided into the shoot by side cheeks 32 and a finger 33 operated by a lever 34 and a cam (not shown) removes from the shoot blanks which have been incorrectly positioned. A member 35, pivoted at 36, covers the shoot to keep the blanks in place and is given an up and down movement to allow the latter to pass by means of a link 51 attached to the guide 43, and a return spring. The conveying member 38 lifts a blank into contact with the positioning guide 43 and oscillates the latter about its pivot 42<1> in bringing the blank into engagement with the saw. The guide 43 in its upward movement lifts the member 35 and also a finger 40 which is normally maintained by a spring in engagement with the last but one blank in the shoot. An adjustable stop 45 limits the downward movement of the guide. The conveying member may coact with the guide to grip the blank before meeting the saw, as shown in Fig. 5. The side members of the shoot are adjustable to accommodate blanks of different size. Lubricant is supplied by a pump 47 and the finished screws fall into a cup 46. An ejector may be provided to remove the screws from the conveying member 38, but usually they are removed by the end of the shoot on the return movement.
