Title: Improvements in or relating to methods of manufacturing semiconductor devices
IPC: H01L21/308
Filed: 1961-10-06
Abstract: 991,291. Semi-conductor devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Oct. 6, 1961 [Oct. 11, 1960], No. 36024/61. Heading H1K. In a method of making a device comprising a body of semi-conductor material having a surface layer of a given conductivity type and an underlying part of the opposite type, after the surface layer and underlying part have been provided with contacts and these have been connected to a measuring device, the surface layer is irradiated with light and treated to remove material from the layer while the photoelectric output of the device is being measured, removal of material being stopped while the output is still monitored. Production of the device shown in Fig. 6 starts with a disc of gallium doped silicon on which a uniform N- type surface layer is formed by a diffusion treatment in a phosphorus atmosphere. The disc is masked with beeswax except for a central area on one face, and etched with aq. HF/HNO 3  to produce the pit shown. After removal of the masking an electrode 5 of Ag/2% Al is provided on the body 1 and the annular pure Ag electrode is soldered to the surface layer 2. Leads fixed to these electrodes are connected to a measuring device. The semi-conductor device is again masked except for face 9 and etched to remove material from the surface layer 2. Assuming the etching rate to be constant the curve of output v. etching time, shown in Fig. 6, represents the relationship between output and decrease in thickness of the surface layer. Similar curves are also formed with semi-conductors other than silicon. The output of the device is continuously monitored to ensure that etching is not   stopped before d<SP>2</SP>I/dt<SP>2</SP> = 0 (at point 22), and etching is preferably continued until dI/dt = 0, at the point of maximum sensitivity 21. After removal of masking the device is protected with a lacquer layer (broken lines in Fig. 6). The removal of material from the surface layer may also be carried out by grinding, sand-blasting, electron bombardment, of electrolytic etching. In some of these cases the treatment and monitoring are rapidly alternated to avoid interference with the measurements. While the invention is primarily used for the production of high output photo-electric devices it is also applicable to the manufacture of transistors and diodes with thin surface layers of accurately determined depth.

Title: Improvements in change speed gears
IPC: F16H3/70
Filed: 1935-12-31
Abstract: 469,880. Variable - speed epicyclic gearing. KOHN, H., and WEIGLE, E. Dec. 31, 1935, No. 36101. Convention date, Jan. 2. [Class 80 (ii)] Continuously -variable speed epicyclic gearing comprises a three-element bevel train wherein the planet - carrier 35 is connected, through a rotatable casing 37, with the driving shaft 36 ; one side-gear 41 is connected to the driven shaft 38, and the speed of the other side-gear 42 is controlled by controlling the speed of the planet-carrier 47 of an additional two-element train, comprising a sun-wheel 44 secured to the side-gear 42, and an internally-toothed planet-wheel 45, driven by the driving shaft 36, through a universally jointed shaft 49. Additional means are provided whereby the torquereaction acting on the planet-carrier 47 is compensated partly or wholly by a torque acting in the opposite sense, so that only small braking or variable driving forces are necessary for controlling its speed. Such means includes a disc 48, journalled on the planet-carrier 47, and constituting a coupling between the universally-jointed driving shaft 49 and the internally-toothed planet-wheel 45, which latter has driving notches engaged, with clearance, by radial teeth 48<1> on the coupling-disc 48. The planet-carrier 47 carries the coupling-disc freely on a pin 47<111>, the axis C of which is radially displaced, adjustably or otherwise, from the axis B of the planetwheel 45. Only one of the teeth 48<1> is in driving engagement with the planet-wheel notches at any one time, so that the jointed shaft 49, in addition to driving the planetwheel 45 on its own axis B, applies a torque to the planet-carrier 47 in opposition to the torque-reaction thereon. The resultant torque on the carrier can be forward, backward or zero according to the radial position of the pin 47<111>. The speed of the planet-carrier 47 is controlled either by a band-brake 52, acting on a shaft 47<11>, secured to the carrier, or by variable-speed gearing, not shown or described, acting on the carrier through planetary wheels 60. A one-way clutch 51 prevents the planetcarrier 47 from overrunning the driven shaft 38, and is retracted bv the same control-sleeve which applies the brake 52. The ratio of the planet-wheel 45 to its sun-wheel 44 is two to one, and a solid direct-drive is obtained.

A machine for grading and sorting shrimps, crayfish or prawns, and particularly the latter from which the head and legs, and possibly the tail-fins, have been removed, comprises one or more pairs of downwardly inclined diverging rotating rollers 7 on which the prawns are caused to traverse lengthwise so that they fall between the rollers and on to transverse conveyer belts 31, 32 at positions dependent on their transverse dimensions. The rollers are supported in a framework 2, 3, and each roller is mounted on a spindle 9 and consists of a parallel sided part 7a with helical ridges at the input or feed end, followed by a tapering part 7b also with helical ridges, and a parallel-sided part 7c at the opposite end. The spindles are supported in transverse bars 5, 6 and have intermeshing driving pinions 12 at their input ends so that all the spindles rotate together. The parts 7b and 7c of each roller are integral and fixed to the spindle, whereas the part 7a is rotatable on the spindle and is driven at a slower speed by a pinion 20. The direction of rotation of each roller of a pair is such as to prevent the fish being carried into the " nip." A flicker roller 8 is associated with each feed roller ; it is mounted between support bars 4, 5 and driven in the same direction by a driving band 8a. The flicker rollers have longitudinal ridges and keep the fish in the space between adjacent rollers. As shown in Fig. 8, partitions 38 extend from longitudinally adjustable supports 39 to adjacent the transverse conveyer belts 31, 32, and define adjustable paths for the falling fish and thereby the size of fish received at each conveyer. A photo-electric cell may scan each prawn just prior to its delivery to the sorting and grading apparatus so that undersized and damaged prawns are detected and removed by an air blast or other means. The machine may be used in combination with the fish processing apparatus of Specifications 911,976 and 911,979.
