Patent AT-E5115-T1 (AT)
IPC: H01L29/43
Filed: 1981-04-14
Granted: 1983-11-15
Abstract: Gold is preferred as the conductor material in a metallization layer of a semiconductor device because of its high conductivity and freedom from electromigration effects but gold is inclined to diffuse into the semiconductor substrate typically silicon, so degrading the p-n junction characteristics within the semiconductor substrate and rendering the device inoperative. Previously this problem has been overcome by placing a protective barrier layer of titanium between the gold layer and the substrate. The gold/titanium interface is subject to corrosion and this corrosion adjacent the substrate containing the active areas of the device also leads to failure of the device. This is prevented by covering the gold metallization layer of the device on its top, bottom and side surfaces with titanium. This prevents the diffusion of the gold into any other layer of the semiconductor device above or below it and there is no gold/titanium interface exposed adjacent any active area of the device.

Abstract: PCT No. PCT/DE81/00158 Sec. 371 Date Jan. 11, 1983 Sec. 102(e) Date Jan. 11, 1983 PCT Filed Sep. 30, 1981 PCT Pub. No. WO83/01307 PCT Pub. Date Apr. 14, 1983.A device for the determination of the charging level in a container has a vibrator on which two torsional vibrators (10, 12) of the same resonance frequency vibrate in an opposite way. The vibration elements (10, 12) are arranged coaxially and have a common center of rotation (20) which is located in the center of a diaphragm (14) serving as a return spring for the outer element (10). The inner element (12) is designed in the shape of a rod and has a tapering (17) in the area of the center of rotation (20) acting as a return spring. Owing to the design according to the invention, a charging level determination is possible with goods charged of a high and of a low density whereby the detection sensitivity is almost independent of the clamping conditions of the vibrator.

Abstract: The inventive concept provides an immunoassay using an enzyme label, in which the detection of the unknown substance is performed colorimetrically directly upon a solid surface. Preferably, the surface is an impermeable surface of a dipstick. To detect antigen in a biologically derived fluid sample, a dipstick containing bound antibody may be contacted with the sample and with a soluble enzyme-labeled antibody, to cause the antigen to bind to both the immobilized antibody and the labeled antibody on the surface. After separation of unreacted reagents, the solid surface is contacted with a substrate which converts from a soluble form to an insoluble colored form in the presence of the enzyme and deposits upon the surface of the solid surface. The solid surface is separated from the solution. The sandwich immunoassay technique may also be employed to detect antibody in the sample by reversing the roles of the antigen and antibody. The system is also applicable to a competitive binding technique. The invention further includes a colored dipstick produced by this means.

Abstract: For the non-clogging, fractional desublimation of vapor-phase solids contained in a gas-vapor mixture, the gas-vapor mixture, exiting at high velocity from a nozzle, is mixed with a cooling gas, likewise exiting at high velocity from another nozzle. The gas-vapor mixture and the cooling gas flow toward each other, the axes of the two gaseous streams being a straight line. Fractional desublimation of the solids is attained by adjustment of flows leading to the regulation of the temperature and residence time of the cooled gas-vapor mixture. This desublimation system is capable of degrees of efficiency and solids purities higher than 99%.

Abstract: A two way open-end wrench has a rotatable, captive, split socket which is selectively locked and unlocked to the wrench handle for torque transmittal through the meshing engagement of two opposed sets of teeth. One set is disposed around the periphery of the open-sided socket member and the other within the forward, concave end of a spring-loaded coupler disposed partly within and partly outside the wrench body. Engagement of the teeth is effected by the inward movement of the coupler when a user grips the wrench handle preparatory to turning it. Relaxation of the grip at the end of a stroke permits the handle to be returned to the starting position while the socket remains stationary. A projecting extension on the socket provides for manual rotation to the open position, permitting the tool to be withdrawn from a fastener on a tubing line, pipe or cable.
