Title: Improvements in or relating to methods of applying metallic coatings to the surfaces of semiconductor and metal bodies
IPC: H01L21/288
Filed: 1957-12-31
Abstract: A method of producing a coating on a semi-conductor body or on a metal electrode for use in a semi-conductor device comprises the steps of immersing the body or electrode first in an alkaline solution of a gold compound to produce a deposit of gold thereon and secondly in an acid solution of a compound of antimony, arsenic or bismuth while contacting the body or electrode with a metal which will displace the Sb, As or Bi from the solution on to the gold, and then removing from the solution and heating to diffuse the Sb, As or Bi into the gold.  In one embodiment a wafer of N type silicon prepared by etching in a mixture of concentrated nitric and hydrofluoric acids, followed by lapping, is immersed in a solution comprising potassium gold cyanide, potassium hydroxide and water which is heated at a rate of 2 DEG C./minute to 70-80 DEG C. and maintained at that temperature for from 20-80 minutes.  The resulting gold plated wafer is degreased and then immersed in a warm solution comprising antimony trichloride, hydrochloric acid, water, and a commercial wetting agent with the gold in contact with a metal such as copper, nickel, brass or aluminium, to produce a thin deposit of antimony on the gold. After successive rinses in hydrochloric acid, water and acetone, and drying, the plated wafer is heated first to 400-450 DEG C. for 15 minutes in nitrogen to diffuse the antimony into the gold and then for 5 minutes at 700-900 DEG C. to alloy the doped gold to the wafer to form a low resistance contact therewith. An external lead may then be soldered to the gold.  In another embodiment an aluminium strip is plated by the above mentioned processes and after the heating to diffuse the antimony into the gold is heated in contact with a body of N type semi-conductor to form an alloyed ohmic contact therewith.  Specifications 706,849 and 769,673 are referred to.

Title: Acquisition system for slide analysis
IPC: G06V10/10
Filed: 1974-09-20
Abstract: 1476694 Positioning a slide CORNING GLASS WORKS 20 Sept 1974 [26 Sept 1973] 41039/74 Heading G1A In an apparatus for adjusting the position of a specimen, a blood cell, on an analytical slide 10 for microscopic analysis using a vidicon target scanning unit 36, the slide is positioned by means of a X positioning motor 56 and a Y positioning motor 54, under the control of logic circuitry 52, until the image of a specimen is central of an aperture 28. Light from a source 12 is directed via a lens 14, fold mirror 16, condenser lens 18 and the slide 10 on to a beam-splitter 22 that directs some of the slide's image to rotating multi-faceted mirror and some of the light via mirrors 24 and 26 to an aperture 28 in front of the vidicon unit. (The vidicon unit blood cell classification is subject of copending Application No 16412/74 Pat No 1456317). The rotating mirror effectively scans the slide 10, in the "X" direction, also Figs. 2A- 2D (not shown) and the reflected beam is directed as shown on to a photo-sensitive device 40 (The other two photo-sensitive devices form part of the automatic focusing system subject of Specification 1476693). The photo-sensitive device 40 produces a pulse signal when the area of the slide being scanned contains a specimen of interest, and this pulse signal is sent via pulse shaping circuitry 46 to the logic circuit 52 that also receives a pulse signal from a source 48 and detector arrangement 50 that are arranged, as shown, to produce a synchronization pulse at the beginning of each scan. The logic circuitry 52, also Figs. 3A, 3B, 3C (not shown) produces a "normal stage motion signal" at the end of each scan within which no specimen has been detected, and this signal is applied to the "Y" positioning motor 54 to move the slide one increment in the "Y" direction. The logic circuitry uses the synchronization signal to produce a centre pulse signal which occurs in the middle of each scan and this signal causes, when a pulse due to a specimen occurs, the activation of the "X" positioning motor 56 which drives the slide in the "+X" or "-X" direction depending on whether or not the specimen signal occurred before or after the centre pulse signal. The X positioning motor 56 is activated until the specimen is at the centre of the scan and when this happens a specimen centered signal is produced which stops the X positioning motor 56 and activates the vidicon scanning unit 36 to scan the specimen blood cell.
