  • Method for forming silicon carbide chrome thin-film resistor
    Patent number: 6211032
    Abstract: A method for forming a thin-film resistor, which is composed of silicon, carbon, and chromium, is disclosed. The resistivity of the thin-film resistor, and therefore the resistance and temperature coefficient of resistance (TCR) of the resistor, are tailored to have specific values by varying the elemental composition of the silicon, carbon, and chromium used to form the resistor.
    Type: Grant
    Filed: November 6, 1998
    Date of Patent: April 3, 2001
    Assignee: National Semiconductor Corporation
    Inventors: Mark Redford, Yakub Aliyu, Chic McGregor, Rikki Boyle, Haydn Gregory
  • Silicon carbide chrome thin-film resistor
    Patent number: 6081014
