Title: Improvements in or relating to the Manufacture of Semiconductor Devices.
IPC: H01L21/22
Filed: 1968-04-24
Abstract: 1,151,830. Semi-conductor devices. NATIONAL CASH REGISTER CO. 24 April, 1968 [10 May, 1967], No. 19360/68. Heading H1K. In forming a semi-conductor device a silicon dioxide layer for use as a diffusion mask, or, if doped, as a diffusion source is formed on a semi-conductor body by drying a colloidal dispersion of the dioxide on it. In the examples boron and phosorus doped layers are prepared from dispersions in aqueous solutions of boric acid and ammonium phosphite respectively. In making PN diodes in multiple an undoped oxide layer is first formed by a'method in which a N (or P) type silicon wafer is spun to evenly distribute the suspension, and apertured by photoresist masking and etching in buffered hydrofluoric acid. Then boron (or phosphorus) doped dioxide is similarly deposited over the masked wafer. After heating at an elevated temperature to form diffused PN junctions the wafer is subdivided and the resulting single junction elements provided with electrodes. To form transistors, after the diffusion apertures are etched in the doped oxide coating within the original apertures, a coating of the opposite type dopant is applied overall and the wafer heated again to form second PN junctions within the first junctions. In all cases, prior to diffusion, the oxide may be densified by heating at a lower temperature in nitrogen. The method is particularly suited for use with Ge, Ge-Si alloy or A II , Bv compound wafers, the appropriate impurities for which are specified

Abstract: 302,946. Angus & Co., Ltd., W., and Phillips, J. E. July 23, 1927. Expanding tables.-Relates to expanding tables of the kind, such as are described in Specification 210,469, comprising a fixed frame 10 and two ends leaves 14 telescoping over depressable centre leaves 15. To extend it, a part 14 with its strengthening-strip 17 is raised until the shoulder 30 of the runner 12 is disengaged from the end member 11 of the frame. As the runner is drawn out, the curved edge 31 of the runner 12 causes the leaf 14, 17 to rise, and the runner falls upon and slides outwards on the cross strip 25; simultaneously the peg 39 is withdrawn from the corresponding slot in the other extension leaf 14, and the centre leaves 15 are raised by the inner ends of the runners 12 engaging with " cleats " 18 on their undersides. The outward movement is limited by stops 40; afterwards the part 14 is pushed in and engages with the centre leaves. The notches 32 in the runners engage with parts of the end members 11, and the leaves 15 meet over the centre strip 13. When the leaves 14 are in the " extended " position, notches 36 in the ends of the runners 12 engage with slots beneath the centre strip 13, and are locked there. The ends of the table may be rounded, or have rounded corners.

Abstract: 442,353. Automatic exchange switches. CLAYTON, C. E. EVERY-, 51, Chancery Lane, London.-(Nationale Telephon-und Telegraphenwerke Ges.; 136, Mainzerlandstrasse, Frankfort-on-Main, Germany) July 9, 1935, No. 19650. [Class 40 (iv)] A selector set by stored energy, such as gravity or a spring motor, is restored to normal by an endless band conveyer provided at intervals with means for engaging the selector. In the arrangement shown in Fig. 1, the brush carriage z drops by gravity during the setting movement and on release drops further to the position shown at D1 where a pawl k pivoted at a engages a fixed stop s and is thrust into the path of one of a series of members m carried by an endless band b. The arrangement is such that the brush carriage z gradually picks up the drive until pawl k meets abutment f, as shown at Cl, whereupon the drive is directly transmitted, the carriage being decelerated when the driving member m commences to pass around the upper wheel ro, the pawl eventually taking up a vertical position as shown at B1. In order to prevent damage if the switch jams, the abutment f may be constituted by a pair of springs f1, f2 of which f normally holds the pawl in the position shown at A2. The springs and pawl take up the position shown at B2 during re-setting under a normal load, but if the load is excessive, the driving member m escapes from the pawl as shown at C2 and D2. It may be arranged that the brush carriage cannot be moved in the setting direction when the pawl is thus put out of action. A single band b may be provided for a group of switches or separate bands may be provided as in Fig. 3 with the switch driving members m staggered to avoid the necessity of accelerating several switches simultaneously. The driving shafts wo, wu may be discontinuous, the breaks in the shafts being staggered and the drive transmitted from one shaft section to another by means of the bands b themselves. The switches on the front and back of a frame may be controlled by two separate bands, the driving shafts of which are geared together, or by a single set of bands, the two shafts of which are driven in opposite directions, alternate bands having fixed and loose pulleys on the upper shaft and loose and fixed pulleys on the lower shaft respectively. The shafts may be driven by a motor individual to a switch or group of switches and where separate motors drive a number of shafts, the shafts may be connected by one-way drives so that if a motor fails, the shaft it controls is driven by another motor.

Printing yarns, threads, and the like.-Artificial filaments, yarns, threads, ribbons, tapes, straws, &c. obtainable by extrusion are given permanent colourations, at intervals along their lengths, by the application, continuously with the production of the filaments &c., of one or more suitable dyestuffs. The colouration of filaments &c. of viscose, cuprammonium, or nitrocellulose silk, cellulose acetate, formate, propionate, or butyrate, and methyl, ethyl, or benzyl cellulose is specified. The dyestuffs may be applied by methods similar to those employed according to Specification 325,823, [Class 2 (ii), Cellulose &c.], for applying a solvent or softening agent, or by printing the filaments &c. by means of an embossed or indented roller to which the dyestuff is supplied in liquid or paste form. A suitable apparatus is shown in Fig. 1. The filaments 6, drawn by a feed roller 7 from the dry-spinning cell 5, pass by a guide 8 to the cap-spinning apparatus 9, and between the roller 7 and the guide 8 they contact normally with a wick 10 supplied with liquid colouring matter from a container 11, fitted if necessary with a heating pipe 15. The filaments are lifted at intervals clear of the wick 10 by radial arms 13 on a rotary shaft 12, and, if desired, by other radial arms 17 on a second rotary shaft 16, the ends of the arms being grooved to engage the filaments. For colouring a large number of yarns or threads simultaneously a rotary drum may be used carrying peripheral slats covered with fabric supplied with liquid colouring matter by endless bands or wicks passing under a rod or roller immersed in the liquid in a trough, the slats contacting intermittently with the yarns &c., which thereafter are dried, if necessary, by passing over a heated plate or chamber.

[Class 122 (iii).] Engines working on special systems or cycles ; compound engines.-In a regenerative steam engine of the kind described in Specification 268,864, [Class 122 (iii), Steam engines, Kinds &c.], heat equal to the excess heat absorbed during the instroke of the ram G is extracted from the heating surfaces during the exhausting period when the working ram is near its extreme outer limit. The exhaust valve may be placed at the hot end of the system and wet exhaust steam may pass over the internal heating-surfaces, or an additional exhaust valve may be so arranged, only a part of the exhaust steam passing over the interior surfaces. Alternately water or wet steam may be injected at the hot end of the system during the exhaust period, and passed out through an exhaust valve after passing over the interior heated surfaces. The cylinder A is connected by pipe B to heating-tubes C in the furnace of the low-pressure boiler D. The tubes C are connected to a header E connected to the exhaust valve F. The water from the cylinder A is forced during the instroke along the tubes C to the header E and the closure of the valve F is arranged so that the critical temperature and pressure are reached or passed. During the out or power stroke of the ram G, evaporation in the tubes C maintains the pressure. On completion of the power stroke, the valve F is opened to exhaust fluid to an exchanger H which acts as a condenser for the steam and as a heater for the boiler D. The steam exhausting, and the evaporation of water entering the tubes from the pipe B, cools them. The condensate from the exchanger H is passed by a pump J back to the system, or some may be returned to the tubes C to cool them.
