摘要： The adjustment of the temperature coefficient of resistance (TCR) of a thick film resistor by laser annealing is disclosed. The thick film resistor is fired for a controlled time and temperature sufficient to burn off the organic material in the resistive paint, and to provide an initial adjustment of the (TCR), but prior to obtaining the desired (TCR) range. The resistor is then laser annealed to controllably adjust the (TCR) of the resistor within the desired (TCR) range. The fixture used to hold the substrate during laser annealing is preferably controllably heated to avoid thermal shock to the resistor during laser annealing. A microprocessor is preferably used to monitor the (TCR) during the laser annealing process. At least one of the laser scan speed, laser beam diameter, laser beam power, and number of annealing passes are used to controllably adjust the resistor (TCR) to within the desired (TCR) range.

摘要： A glaze resistor composition composed of magnesium silicide, molybdenum disilicide, tantalum disilicide and glass frit, and if necessary, manganese disilicide and/or aluminum oxide. Due to the use of magnesium silicide, glaze resistors having stable resistivities in a wide resistivity range can be obtained. Due to the use of manganese disilicide, the temperature coefficient of resistivity can be shifted to the positive side, and due to the use of aluminum oxide, the resistivity can be increased and made more stable. This invention also provides a method of making a glaze resistor using two heating steps, in which aluminum oxide is mixed in the starting powder mixture to be subjected to the first heating step, so as to enhance the effect of the aluminum oxide addition.

The method is characterized in that intermediate layers consisting of a metal having a temperature coefficient different from the temperature coefficient of a resistor film and capable of preventing diffusion of the soldering material and readily solderable terminal metal layers are provided on terminal parts of the resistor film and the temperature coefficient of resistance is minutely adjusted by removing parts of said intermediate layers.

摘要： Methods of forming a thin film are disclosed. One such method can include sputtering a target material to form a first thin film resistor and adjusting a parameter of deposition to modulate a property of a subsequently formed second thin film resistor. For instance, a substrate bias and/or a substrate temperature can be adjusted to modulate a property of the second thin film resistor. A temperature coefficient of resistance (TCR) and/or another property of the second thin film resistor can be modulated by adjusting the parameter of deposition. The target material sputtered onto the substrate can include, for example, a Cr alloy, a Ni alloy, SiCr, NiCr, or the like. A relationship can be established between the substrate bias and/or substrate temperature and the thin film resistor property, and the relationship can be used in selecting deposition conditions for a desired property value.

摘要： To form a temperature sensor, for example suitable in an automotive vehicle, to determine ambient temperatures, or to provide a temperature compensated thin-film circuit, for example for incorporation with an oscillator circuit, two stable thin-film layers are applied to a non-conductive substrate, the layers being capable of being etched. The overall temperature coefficient of resistance can be matched to a predetermined value by selective interconnection of at least two thin-film resistance elements formed by the thin films, of which one thin film resistance element for example comprises a nickel layer over a tantalum base, with a predetermined temperature coefficient of resistance, the other resistance element merely being the tantalum layer with essentially zero temperature coefficient of resistance, the overall temperature coefficient of resistance of the combination being determined by adjustment of the relative resistance values after measurement of the temperature coefficient of resistance of the nickel-tantalum layer to determine its actual temperature coefficient so that, in spite of tolerances in the manufacture of the thin films, interchangeable elements of highly accurate overall resistance and temperature coefficient of resistance values can be obtained.
