Title: Method and structure in forming electrically continuous circuit through insulating layer
Inventor: LATHROP JAY WALLACE
IPC: H01L21/00
Filed: 1968-10-30
Abstract: 1,240,189. Semi-conductor devices; printed circuits. TEXAS INSTRUMENTS Inc. 30 Oct., 1968 [14 Feb., 1968], No. 51454/68. Headings H1K and H1R. In a semi-conductor arrangement contact layers at different levels separated by insulation are interconnected by metal deposited electrolessly to fill apertures in the insulation. A typical integrated circuit arrangement, shown in Fig. 9, is made by first forming an insulating layer 102 over diffused transistor and diode configurations 82-88 in silicon wafer 80 and etching to expose zones to be contacted. Molybdenum 196 is then deposited overall by R.F. sputtering or vapour deposition followed by gold 194 and a further layer of molybdenum, and the metal etched back to form the first layer of contacts and interconnections. To improve adhesion a thin layer of palladiumsilicon alloy or aluminium is provided on the silicon before depositing molybdenum 196 and the deposited gold may include traces of platinum to improve its adherence to the molybdenum. A further layer of insulation 106 is next applied and apertured at 108, 110. After removing the molybdenum at the base of the holes and replacing by palladium deposited from chloride solution to improve adhesion, nickel or gold 202, 204 is deposited from an electroless plating solution to fill the holes and cover the insulation at 200. After removal of metal 200 metal 209 is vapour deposited overall and etched back to form an interconnection pattern and contact lands as desired Further layers of insulation and levels of interconnection patterns may be added by the same technique. Silicon oxide is the preferred insulating material though silicon nitride, alumina and tantalum oxide may be used. One or more of copper, gold, silver, tantalum, titanium or even aluminium may be used for the first layers of contacts and interconnections while copper, molybdenum, gold and silver are suitable for filling holes 108, 110. Alternative semi-conductors are germanium and gallium arsenide. Patterning of the layers of metal and insulation is effected by photo-resist and etching steps using cyanide to remove gold and a phosphoric-acetic-nitric acid mix to remove molybdenum. A planar diode with an electrode arrangement according to the invention is also described.

Abstract: 1,134,835. Deflecting propulsive jets. UNITED STATES OF AMERICA. NAVY, SECRETARY OF. 6 Dec., 1965, No. 51649/65. The thrust vector of the supersonic exhaust of, for example, a rocket motor, is deflected by the injection of liquid, e.g. N 2 O 4  or "Freon" (Registered Trade Mark), through radially directed orifices 14 in the wall of the divergent portion of the exhaust nozzle 10. This liquid increases the thrust of the rocket and produces an oblique shock wave which deflects the exhaust. For maximum effect, the shock wave should lie as far downstream as possible, but wholly within the nozzle. Four orifices are provided, arranged 90 degrees apart, and the flow from them is controlled by valves to give pitch and yaw control. Four further circumferentially directed orifices 14a, 14b are arranged in radially extending vanes 22 and provide control in roll.

Filed: 1973-11-21
Abstract: 1425909 Polishing vehicle bodies TAKEUCHI TEKKO KK 21 Nov 1973 [27 Nov 1972] 54119/73 Heading A4F [Also in Division B2]  An apparatus for applying wax to the side surfaces of a vehicle having front and back wheels on one side comprises a wax ejecting system, including wax guns 14, 14' arranged on opposite sides of a path along which the vehicle can progress whilst said front and back wheels are guided by a track, e.g. a ground rail G, and means for sensing the position of the vehicle surface remote from said wheels as the vehicle passes between the guns 14, 14'and for controlling the position of the gun 14 on that side so that it is always at about the same distance from the nearest part of the side surface. The gun 14' is carried by a frame 5 fixed to a portal structure 1, whilst the gun 14 is carried by a frame 5 suspended from the structure 1 by a parallel links mechanism 4, 4' and movable inwardly of the structure 1 by a pneumatic actuator 8 against the action of a counterweight 7. When the vehicle is advanced into the structure 1 a phototube detects the advance and energizes the actuator 8 and opens an electromagnetic valve to permit discharge of wax through the guns 14, 14'. The inward movement of the frame 5 by the actuator 8 causes a sensor rod 21 to engage the vehicle to de-energize the actuator 8, which on the resulting retraction of the frame 5 is again energized. Thus the sensor rod 21 maintains the wax gun 14 substantially at a predetermined distance from the side of the vehicle, so that vehicles of different widths may be treated in the apparatus. During the wax application each gun 14, 14' is oscillated to and fro in a horizontal plane by crank mechanism driven by a motor 10, the wax being supplied from a reservoir supplied with air under pressure.

[Also in Division G3] A work-table of a milling machine is movable in X and Y directions by lead-screws, each of which is positioned through a dual input gear, Fig. 1 (not shown), initially, by an inch motor and a decimal motor, then, when the table is within an inch of the desired position, the inch-motor is de-energized and braked and the final positioning effected by the decimal motor, as shown; a sequencing console 118 cyclically operates a pneumatic tape-reader 120 and energizes the inch-motor to move the work-table 14 through the lead-screw 18 to the programmed inch position determined by a mechanism 26 having a large increment positioner 30 responsive to a strip 32. The detection of the inch mark causes the positioner 30 to de-energize and brake the inch motor, a take-over circuit, not shown, causing a small increment positioner 34 to control the decimal motor. The small increment positioner 34 comprises a photo-cell head which straddles a plastic strip 36 carried horizontally by brackets 38 on a saddle 10. The strip 36 carries light guide tubes, Fig. 1, not shown, which are located in multiples of a whole unit from a zero reference line on the strip. The positioners form a table control mechanism 26 which is displaced to the programmed decimal position by a rod 112 connected to a piston 102 in a cylinder 28. The decimal position is read from the tape by the reader 120 and pneumatically actuates selected rams R1a-R1c, R2a-R2c, R3a-R3c which are connected to a manifold 46 and have displacements which are binary coded to cause a corresponding displacement of the piston 102 through a non-return line 44. When the decimal motor has moved the saddle 10 so that a light tube registers with the small increment positioner 34 a work operation is carried out on a work-piece mounted on the table 14. The sequencing console 118 then causes the tape reader 120 to advance the tape and at the same time it energizes solenoid valves 126, 130 to reset the rams and return the piston 102 to its zero reference position.

[Also in Division B5] A method of making a shoe includes the steps of placing an outsole 8 having a heelward extension to which a heel filler 28, 30 is attached in a mould cavity, closing the mould cavity with a lasted upper 7 and injecting plastics material, e.g. polyvinyl chloride, into the cavity to form an edge strip 11 which bonds the outsole 8 to the upper 7, the plastics materal also forming the breast face 15 of the heel. The plastics material is in contact with both the upper and lower surfaces of the heel filler 28, 30 to prevent delamination of the filler 28, 30 and a top lift 50 may be attached to the bottom layer 30 of the heel filler. A conventional rib strip 40 to which the lasting margin is secured contacts the outsole to prevent the flow of plastics material into the central area of the shoe bottom, the region inside the rib 40 being filled by a bottom filler 48 of sponge rubber or ground cork. The mould consists of a base plate, a split side mould 3 and welt plates 4. The edges of the base plate are bevelled to produce a downwardly extending projection of plastics material outside the outsole 8, this projection being removed by buffing after the moulding step. The outsole 8 is positioned on the base plate by locating pins (not shown).
