Title: Improved surface treatment of semiconductor bodies
IPC: H01L21/00
Filed: 1959-07-21
Abstract: A stable moisture-resisting film is formed on the surface of a semi-conductor body etched in a solution containing hydrofluoric acid by quenching in a solution containing an organic liquid having in its chemical structure a reactive hydroxyl group.  Semi conductors referred to are germanium, silicon, germanium-silicon alloys, indium antimonide, gallium arsenide, gallium and indium-phosphorus alloys. In an example a semi-conductor silicon body is immersed in an etchant solution containing hydrofluoric, nitric and acetic acids and a small quantity of a non-ionic wetting agent, e.g. a nonyl ester of polyethylene glycol.  The body is then transferred from the etch within one half-second to a quenching solution which contains a mono- or polyhydric aliphatic alcohol.  As the body is removed from the etch a hydrophilic film begins to form due to Si-OH linkages at the surface.  In the alcohol however the formation of the linkages is inhibited and the hydrophobic Si-OR linkage is formed.  A scavenging compound, a list of which is given in the Specification may be included in the quenching solution.  During aluminium alloy dioide experiments a rapid quench was achieved by adding a large volume of ethanol to a polythene beaker in which the etch is performed.  The Specification includes a list of suitable etch solutions.

Abstract: 260,096. Gerke, A. Oct. 12, 1925. Portable endless - chain push-plate elevators; discharging and feeding devices; directing and adjustably supporting; jigging conveyers.-For filling disused mine galleries, waste material is fed by a jigging conveyer a or other apparatus available in the mine to a trough c, Fig. 1, and is delivered near the roof of the gallery by push-plates working along the trough. In a modification the material is raised from the conveyer a to the roof of the gallery by a conveyer belt or a bucket chain m, Fig. 4, moving in a direction opposed to the feeding movement of the material delivered by the conveyer a. The push-plate elevator, Fig. 1, is mounted on runners b and carries ratchetdriven winding-drums h for shortening a loop of rope h<3> connected with an anchored chain of hooked rods which are removed one by one as the gallery is filled and the machine moved back. The trough c is carried on adjustable pillars k, l. The push-plates d<1> are carried by arms pivoted on two parallel chains d. Pivoted bars d<3> at the top of the run guide the push-plates on to the upper part d<2> of the framework, and there are separate sprockets d<5> for the two chains d so that the push-plates can pass between them. The bearings d<6> for the sprochets d<5> are adjustable along arms d' in order to turn the arms on their pivots d<x> and raise or lower the sprockets. The material may be delivered from the upper end of the trough through a pivoted shoot adjustable laterally and vertically, or the. upper end of the trough may be flared outwardly and provided with a pivoted gate to direct the material toward either side. The material is packed tightly in the working by a ram g, reciprocated by a crank g<1> on the shaft of the sprocket d<11>. This mechanism may include resilient members and a friction clutch. The ram may be driven on its working stroke by spring or air pressure. The material is carried from the conyeyer &c. a to the trough by a jigging conveyer e actuated by pin-and-slot mechanism e', e<2> on the machine. The feed in the trough e moves more slowly than the push-plates in order that these may sink into the material. In a modification a telescopic extension is provided on the end of the convever a, or the lower end of the trough c may be extended to co-operate with the conveyer. A compressed-air motor j on the machine drives the chains d, ram g, jigging conveyer e and winding drums h. The ram may be actuated by a separate motor.

Title: Improvements in or relating to the protective coating of surfaces
IPC: B05D3/02
Filed: 1951-10-31
Abstract: In a method of applying, improving or removing protective coatings on metal or other conductive surfaces the surfaces are subjected immediately before, during or after the application of the coating to alternating magnetic fields of such frequency and energy density per unit area and time that the contact layer between the surface and the coating attains a temperature considerably higher than that of deeper layers of the surface.  An induction heating coil is connected to a self-excited high-frequency generator arranged to maintain automatically the tuning as the inductance of the coil varies with the distance between the coil and the workpiece and the shape of the latter. The method may be used to fuse coatings onto the surface, the coatings being brushed, sprayed or blown on to the surface as a liquid or powder, or applied in solid form as a rod or stick to the heated surface.  Emulsion, suspension or dispersion coatings may be dried and fused to the surface.  Coatings may be applied as films, with or without additional fusible binding agents. Non-metallic surfaces can be treated when provided with suitable conductive coatings, and moist surfaces may be dried before coating.  Fusible coatings may be stripped or removed after the surface has been heated.ALSO:In a method of removing fusible non-metallic coatings from metal surfaces the surfaces are subjected to alternating magnetic fields of such frequency and energy density per unit area and time that the contact layer between the surface and the coating attains a temperature considerably higher than that of deeper layers of the surface.
