  • Method for fabricating controlled TCR thin film resistors
    Patent number: 4226899
    Abstract: High stability thin film resistors are made from an alloy comprising selected portions of nickel, chromium, and gold selected in a ratio to provide the desired temperature coefficient of resistance (TCR). The resistors are made by co-depositing gold with the nickel chromium alloy by a flash evaporation process. The evaporation process is carried out by feeding a nickel chromium wire, having a gold wire extending therealong to provide the desired composition, onto a heated tungsten strip within a vacuum system with substrates disposed in a position to obtain uniform deposition of the evaporated material thereon.
    Type: Grant
    Filed: August 21, 1978
    Date of Patent: October 7, 1980
    Assignee: General Dynamics Corporation Electronics Division
    Inventors: Ronald A. Thiel, Edward H. Maurer
