Patent GB-1420557-A (GB)
Title: Method of making a semiconductor device
IPC: H01L29/792
Filed: 1974-03-22
Abstract: 1420557 Silicon coatings NCR CORP 22 March 1974 [2 April 1973] 12790/74 Heading ClA [Also in Division Hl] In a method of making a device such as a memory IGFET a layer 22, 24 of silicon oxide is formed on the surface of a semi-conductor substrate, the layer is then heated in an atmosphere containing NH 3  prior to forming a further layer 30 of silicon nitride over the oxide layer. It is stated that the step of flushing the oxide surface with NH 3 , or a compound producing NH 3  such as hydrazine, prevents the formation of oxynitride products on the oxide layer before deposition of silicon nitride to increase the switching rate of the IGFET. The substrate is preferably Si but may be silicon carbide, Groups III-V or Groups II-VI compounds. As described a first portion 22 of silicon oxide is formed by thermal oxidation of a Si substrate and portions are etched away to allow the diffusion of boron to form drain and source regions 14, 16 and to expose the surface above the channel zone 38. The substrate is then placed in a chemical reactor vessel (Fig. 1, not shown) through which N 2  is fed throughout the process. The second portion 24 of the silicon oxide layer is formed by heating the substrate in a stream of O 2  and the oxide layer is then flushed with NH 3 . The silicon nitride layer 30 is deposited by introducing a gaseous mixture into the reactor such as SiH 4  and NH 3 , SiCl 4  and NH 3 , SiH 4  and hydrazine or dichlorosilane and NH 3  whilst heating the device. The device is completed by photolithographic techniques, selective etching and metal deposition to form electrodes 32, 34 and 36.
Patent GB-202010-A (GB)
Title: Improvements in and relating to the cleaning of the interior of tubes, specially applicable to cleaning condenser tubes
Filed: 1922-05-08
Abstract: 202,010. Carr, A. E. May 8, 1922. Cleaning, fluid-pressure processes for.-The interior of a tube, more particularly a condenser tube, is cleaned by injecting into it, from a nozzle 2 applied to one end, a jet of hot wet air formed by the mixture in a throat-tube 5, of a jet of steam from a jet-tube 13, with currents of cold air induced through holes 3 in front of the barrel 1 of the apparatus, which currents serve also to keep the barrel and throat-tube cool. Steam is led to a connection 8, secured to a block 6 held in the rear end of the barrel, and its supply to the jet-tube 13, via the annular space 7 and the ports 19, is controlled by a valve 10, formed by the rear end of the jet tube. The valve is lifted from its seat 11 by the longitudinal movement of the handle 16 against the spring 17 as the apparatus is pressed against the tube. This movement first covers the ports 22 of the jettube by the packing-ring 24, so that a quiet starting of the jet results since steam is supplied only through the ports 21. Further movement of the handle and jet-tube causes the steam to flow into the chamber 25a and through the secondary jettubes 26 by the uncovering of the ports 22 when these are to the left of the ring 24. These secondary jets increase the propulsive effect on the air, which effect is further increased by causing the steam to issue from the jet-tubes in a series of puffs, either by disposing a rotating fan-wheel in the path of the steam or by continuously automatically opening and closing the valve port 12. This is done by a piston valve 27. which, in the position shown, permits steam to flow to its rear, causing the piston to move forward and seal the port. As it moves forward, the port 20 leading to the rear is closed and the steam pressure on its forward face, caused by the flow of steam through the port 19, pushes it back again into the position shown, when the sequence of operations is repeated.

Abstract: 921,233. Electric heating resistances. GENERAL ELECTRIC CO. Ltd. July 7, 1961 [April 11, 1960], No. 12904/60. Class 39 (3). A source of thermal radiation comprises an open-fronted vessel of refractory material containing a radiator element and provided with a gas inlet and with a screen of closely spaced fine refractory wires extending across the front of the vessel, the screen being such as to provide a barrier against the ingress of ambient air or gas whilst permitting thermal radiation to pass through it. As shown, one embodiment is a furnace having a casing 11 provided with a screen of fine iridium-platinum alloy wires 16 mounted in zig-zag fashion on tungsten rods 14, 15 across its open front. The rods 14, 15 are supported by blocks 13 of insulating material carried by a frame 12 of refractory material. The wires 16 may be electrically heated, terminals 17, 18 being provided for that purpose. The frame 12 is attached to the casing 11 by means of a single wing-nut 19 and is thus removable to give access to the interior of the furnace. Inert gas is supplied to the furnace through an inlet (not shown) to reduce oxidation and corrosion of electric heating elements (Fig. 2, not shown) within the furnace, the flow of gas from the furnace being restricted by the screen. A second embodiment and the heating elements included in both embodiments, are the same as those described in Specification 921,234.
