Abstract: 1,236,054. Semi-conductor devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 4 Oct., 1968 [7 Oct., 1967], No. 47135/68. Heading H1K In a method of manufacturing a semiconductor device comprising a semi-conductor body in which there is a transistor T, having emitter 2, base 3 and collector regions 4 extending to one surface of the body, after the steps of forming a diffusion masking layer 5 on this surface, providing a base diffusion window 15 in this layer, diffusing the base impurity through the window, closing the window with a further masking layer, forming a smaller, emitter diffusion window in this layer and diffusing the emitter impurity through it, the base diffusion window 15 is reopened substantially entirely and the exposed semiconductor surface is provided with a new insulating layer 12 in which apertures 6, 7 are formed to allow contact to be made to the emitter and base regions. The diffusion masking layers and the new insulating layers may be of silicon oxide or silicon nitride, and the new insulating layers, which may be provided with a surface layer of phosphorus glass to promote stability of the device, are provided by thermal oxidation, or where a very thin emitter region is required, pyrolytically or by sputtering. This process can be applied to other windows 17, 18, 37, which have been formed elsewhere on the semi-conductor body during the formation of the emitter diffusion window, as in the case where the method is applied to integrated circuits. Conductors of aluminium may be deposited over the insulating layers from the vapour phase. Silicon is used as the semiconductor material, doped with boron and phosphorus as required.

Patent GB-481223-A (GB)
Abstract: 481,223. Electric control systems. GENERAL ELECTRIC CO., Ltd., and COLLYER, J. E. Dec. 28, 1936, No. 35495. [Class 40 (i)] In a system, in 'which carrier currents are sent over power mains to effect switching at a remote point, an interrupted carrier switches the lights on, while the uninterrupted carrier is used to switch them off. An oscillator 7 supplies carrier current, e.g. at a frequency of 20 k.c., to a switching device 8, depression of key 11 causing emission of uninterrupted carrier, while key 10 causes the carrier to be emitted, interrupted at, e.g. a frequency of 25. Carrier current is fed on to the line wires 3 by transformers 14, 15 the primary of transformer 14 being approximately tuned to the carrier frequency by the condenser 12 which also prevents feed-back of the power frequency into the oscillator 7. When key 10 is depressed interrupted carrier passes through condenser 26, Fig. 2, rectifiers 24, a vibratory type relay 20 and relay 50 which is of the slow-to-operate pattern and is therefore unaffected. The contact 27 of the relay 20 allows current to pass through thermostat 30 which warms up and closes its contact 31 thus energizing relay 35 to close contacts 38, 39 locking the relay 25 and switching on the consuming device 5. A continuous carrier causes relay 50 to open contact 51 and close contact 28, thermostat 32 heating and causing the relay 35 to be de-energized. If an interrupted carrier is applied at the same time as the uninterrupted carrier, the former is ineffective since the contact 51 remains open. Instead of relay 35 the bi-metallic strips of the thermostats may rock a two-position lever. Specification 481,213 is referred to.
