    Abstract: In one aspect, a negative voltage coefficient resistor is provided. The negative voltage coefficient resistor includes an insulative layer positioned between a polycrystalline silicon resistive layer and a silicide layer. Upon application of an appropriate voltage bias at the silicide layer of the resistor, a tunneling current is established across the insulative layer and is supplied to the polycrystalline silicon resistive layer. The tunneling current limits the current flow through the polycrystalline silicon layer, producing a resistor having a negative voltage coefficient of resistance and a reduced temperature coefficient of resistance.

    Abstract: A high temperature hybrid-circuit structure includes a temperature sensitive device which comprises SiC, AlN and/or AlxGa1nullxN(x>0.69) connected by electrodes to an electrically conductive mounting layer that is physically bonded to an AlN die. The die, temperature sensitive device and mounting layer (which can be W, WC or W2C) have temperature coefficients of expansion within 1.06 of each other. The mounting layer can consist entirely of a W, WC or W2C adhesive layer, or an adhesive layer with an overlay metallization having a thermal coefficient of expansion not greater than about 3.5 times that of the adhesive layer. The device can be encapsulated with a reacted borosilicate mixture, with or without an upper die which helps to hold on lead wires and increases structural integrity. Applications include temperature sensors, pressure sensors, chemical sensors, and high temperature and high power electronic circuits.

    Abstract: The PTC thermistor material of the invention comprises a matrix phase and electrically conductive phases substantially uniformly dispersed in the matrix phase, said conductive phases having a resistivity lower than that of the matrix phase, and has a resistivity changing sharply in the vicinity of the melting point of the conductive phases. The matrix phase is made up of any one of a polycrystalline ceramic material, a glass-polycrystalline ceramic composite material, a glass, a crystallized glass, and a polymer material, and the conductive phases are made up of a metal containing bismuth as a main component. It is thus possible to achieve a PTC thermistor material which can be controlled in terms of various properties such as the temperature at which PTCR property becomes available and the rate of resistivity change and so can be applied to circuit parts through which large currents pass in a normal operation state. Further, the PTC thermistor material can be easily manufactured with the stable PTCR property maintained. Furthermore, the PTC thermistor material can be operated with an increased rated current albeit being of small size, and has a high degree of shape freedom.
