Title: Application of glass to semiconductor devices
IPC: C25D5/06
Filed: 1964-10-06
Abstract: <PICT:1073758/C1/1> A glass coating is applied to a semi-conductor body by applying a slurry of glass and a photo resist to the surface, exposing and developing to remove the slurry from selected areas and heating to remove the remaining resist and fuse the glass to desired areas of the body.  The glass may consist of lead borosilicate glass and the resist of Kmer.  The mixture is prepared by grinding the glass with hard alumina balls in polyethylene bottles containing methyl alcohol, filtering off the methyl alcohol, and adding the ground glass to xylene to leach out traces of polyethylene.  The xylene is filtered off, and since drying is undesirable a sample is used to determine the proportion of xylene remaining so that the bulk may be brought to a standard xylene level.  The resulting paste is mixed in a ball mill with the Kmer photo resist and xylene and applied to the semi-conductor surface by spinning.  The mixture is then baked, exposed to the desired light pattern, and material from the unexposed regions removed by development.  The coated semi-conductor body is dried and the glass fired in oxygen at 500 DEG C.  A layer of silicon oxide may cover the semi-conductor body before the glass is applied.  The figure shows a planar diode with the semi-conductor 1 covered by an oxide coating 3 and glass coating 4 applied to leave an opening for contact 5 to the semi-conductor.

Abstract: 1,045,787. Semi-conductor devices. STANDARD TELEPHONES & CABLES Ltd: Sept. 30, 1965, No.41523/65. Heading H1K. A method of manufacturing a solid state semi-conductor device comprises the steps of providing a wafer 1 of monocrystalline semiconductor material, forming a dielectric layer 2 on one major surface of the wafer, depositing on the dielectric layer a layer 3 of material having a coefficient of expansion corresponding to that of the wafer and a thickness adequate to form a substrate for the completed device, reducing the thickness of the substrate-supported wafer, forming a pattern of electrically isolating grooves 6 in the wafer extending from the other major surface at least down to the dielectric layer, and forming a plurality of P-N junctions in the regions of the waver defined by the grooves by controlled impurity diffusion into the other major surface. In the preferred embodiment, a wafer 1 of monocrystalline n-type silicon is provided with a thin (say 1Á) dielectric layer 2 by vapour phase deposition of silicon nitride or thermal growth of silicon dioxide, and a layer 3 of polycrystalline silicon is deposited on the layer 2. The thickness of the wafer 1 is then reduced by air-abrasion, and the surface coated with photo-resist, masked and exposed to give a desired pattern of windows. Grooves 6 are then etched through the windows by means of hydrofluoric acid, and extend down to the layer 2, if the latter is composed of silicon nitride which is insoluble in HF, or through the layer 2, if the latter is composed of silicon dioxide which is soluble in HF. The exposed silicon surfaces, are then passivated by a thermally grown layer 7 of silicon dioxide, which is used as a mask for the successive diffusion of impurities into the isolated lands 8 to produce p-type layers 9 and n-type layers 10. An aluminium layer is evaporated over the layer 7 and selectively removed to leave, for each transistor, a base contact 11 and an emitter contact 12 which is interconnected with the collector contact 13. of an adjacent transistor. The completed device may be potted in a suitable insulating; material.

[Also in Division F4] A conveying system mounted in the hardening zone of a heat treatment furnace comprises a chain carriage 1, an endless roller chain 2 provided with conveyer cams 3, 3a and stop cams 4, 4a and a driving pinion 5 mounted between the side sections of the carriage on a drive shaft 6 which is mounted in the walls of the fixed drive housing 7, the pinion engaging the upper portion of the chain which rolls on the sides of the carriage, the lower portion of the chain moving on a rail 9 of the fixed housing. Anticlockwise rotation of the pinion wheel moves the chain to the left towards the furnace zone until the cam 4 abuts a cam 12 on the carriage, and the carriage moves to the left into the furnace zone until shaft 6 abuts the end of a slot 13, the drive being lowered to allow the cam 3 to go beneath the loading grid. On reversal of the direction of rotation the cam 3 rises and engages the loading grid and delivers the charge into the hardening zone. After hardening, further clockwise rotation causes the chain to move to the right until cam 4a abuts cam 12a and the carriage moves to the right until the shaft 6 abuts the opposite end of slot 13 the loading grid being pushed out by cam 3a. One half of the chain between the cams 3 and 3a is provided with additional rollers 14 which roll on centring rails 15. An electric or hydraulic motor 11 is directly attached to the drive shaft 6 by a cordan shaft 11a. The system may be used at one end of a furnace for loading and unloading, in which case the cams 3a and 4a and the rollers 14 can be dispensed with.

In examples: 1-amino-3-chloranthraquinone is diazotized and coupled with 2:3-hydroxy-naphthoic acid, the product is converted to the acid chloride by reaction with thionyl chloride and the acid chloride is condensed with 2:5-dichloro-1:4-phenylene diamine to obtain a yellowish red dye (1); 1-amino-3-chloroanthraquinone is diazotized and coupled with 3-methyl-1-phenyl-(31-carboxy)-5-pyrazolone, the product is converted to the acid chloride which is condensed with 2:5-dichloro-1:4-phenylene diamine to obtain a yellow dye (2), and in a similar process aceto-acetic methyl ester is employed as coupling component (3).  Many additional starting materials are listed.  The dyes are suitable for the spin dyeing of rayon, viscose, cellulose ethers and esters, polyamides, polyurethanes, polyesters and for colouring such materials as polystyrene, polyvinyl chloride, polyethylene, polypropylene, polyacrylonitrile, rubber, casein and silicone resins.

Abstract: 1,076,460. Electrolytic capacitors. JOHNSON MATTHEY & MALLORY Ltd. Oct. 5, 1965 [Oct. 19, 1964], No. 42148/65. Heading H1M. In an electrolytic capacitor of the type having a porous anode and a solid electrolyte, the anode 10 has a cross-sectional shape such as that shown so as to reduce to a minimum the length of the mean path between any point in the anode and the exterior surface of the conductive layer forming the cathode lead. The value of the dissipation factor of the capacitor is accordingly reduced, since this is largely due to the resistance of the solid electrolyte permeating the porous anode, and the contribution to the dissipation factor from this source is shown to be proportional to the square of a cross-sectional dimension of the anode. The reduction in impedance of the capacitor due to the presence of the channel is greater than the increase due to the absence of metal from the channel. Other suitable shapes are illustrated in Figs. la and 1c-1h (not shown). The shaped anodes of the invention also minimise the variation of capacitance with frequency and temperature under A.C. conditions, this variation being stated to be due to the distributed arrangement of capacity and resistance within the body of the anode.
