    Tantalum nitride and tantalum aluminum thin-film power resistors were reactively sputtered on 99+ percent alumina ceramic substrates in an argon atmosphere, thermally stabilized, and laser patterned into serpentine paths (two to ten meanders) to obtain final values two to two hundred times their initial values. The resistors were then subjected to many tests to determine their stability. Data from... View full abstract»

    Accelerated life tests under elevated temperarure, high humidity, and vacuum have been conducted on Pd-Ag thick-film resistors It is found that the change of resistance under those accelerated life test conditions is mainly caused by oxidation and reduction of the electrically conductive components (Pd and Ag) of Pd-Ag thick-film resistors. Through life tests in vacuum, the effect of adsorption wa... View full abstract»

    Mechanism of resistance change by high-frequency-discharge trimming has been investigated for RuO2 glaze resistors. As a result, it is found that the resistance of RuO2 glaze resistors eventually increases when subjected to the discharging over an extended period because of structural damage of the resistor films. As for RuO2 · glass resistors, the resistance increases with the increasing dis... View full abstract»

    The variation of resistivity with temperature for thin polycrystalline films of bismuth on BeO substrates is reported. Resistivity minima at temperatures of 90-150°C were observed for films of thickness 0.08-1.0 microns. Experimental results are compared with the theory relating the decrease of the mean free path by grain boundary scattering to the decrease in sample size. View full abstract»

    A method to identify conductive bridge contaminants has been developed using pyrolytic and chromatographic principles. A known contaminant is deposited on the surface of a metal film resistor and placed in a glass test fixture. A load is applied to the resistor with a powerstat until the material becomes active. A sample is taken of the gaseous products and analyzed with a gas chromatograph. Disti... View full abstract»
