  • Patent number: 5679895
    Abstract: An acceleration sensor includes an acceleration mass and a substrate mounted so that a cavity is defined therebetween and so that the acceleration mass moves relative to the substrate when an acceleration of the sensor changes. The sensor also includes a diamond field emitter for generating an electron beam through the cavity between the acceleration mass and the substrate. Accordingly, the distance between the acceleration mass and the substrate affects the current of the electron beam which is measured to determine the acceleration of the sensor. The sensor may alternately include an annular extraction electrode in a cavity between a substrate and a collector together with a diamond field emitter for generating an electron beam which passes through the annular extraction electrode. The annular extraction electrode is moveable relative to the substrate in response to changes in an acceleration acting on the sensor.

  • Patent number: 5536953
    Abstract: A semiconductor device for providing stable operation over a relatively wide temperature range includes a wide bandgap semiconductor active region having an intentional dopant of a first conductivity type and an unintentional impurity of a second conductivity type which together produce a free carrier concentration at room temperature. The concentration of the intentional dopant in the active region is preferably less than 1.times.10.sup.16 cm.sup.-3 and the concentration of the unintentional impurity is less than 0.1 times the intentional dopant concentration so that the intentional dopant concentration will be less than 1000 times the free carrier concentration at room temperature. The intentional dopant concentration supplies substantially all the majority free carriers in the active region. The wide bandgap semiconductor active region is preferably diamond, IV-IV carbides, III-V nitrides and phosphides and II-VI selenides, tellurides, oxides and sulfides.

At least 90% of the surface area of the highly-oriented diamond film is covered with either (100) or (111) crystal planes, and the differences {.DELTA..alpha., .DELTA..beta., .DELTA..gamma.} of the Euler angles, which represent the orientations of the crystals, between adjacent (100) or (111) crystal planes, simultaneously satisfies the following relationship: .vertline..DELTA..alpha..vertline..ltoreq.5.degree., .vertline..DELTA..beta..vertline..ltoreq.5.degree., and .vertline..DELTA..gamma..vertline..ltoreq.5.degree.. In addition, this highly-oriented diamond film can be grown on a non-diamond substrates, and therefore the diamond film with a large surface area can be obtained. Thus, the present invention provides the heat dissipating substrate with an excellent thermal conductivity at low cost.

  • Patent number: 5362975
    Abstract: A chemical sensor includes a diode or a transistor fabricated in diamond. A diamond-based diode chemical sensor includes a first diamond layer of first conductivity type and a second diamond or non-diamond layer of second conductivity type. A relatively highly doped region is formed in the first diamond layer, adjacent an electrical contact to reduce the frequency dependance of the sensor's capacitance/voltage characteristic. A diamond-based transistor sensor includes a controlling electrode such as a gate which is configured to allow a chemical external to the transistor to alter the characteristics of the transistor. Relatively highly doped regions are formed adjacent the transistor's controlling electrodes, such as the source and drain. A heater is thermally coupled to the sensor for heating the sensor to a predetermined operating temperature. A temperature monitor is also coupled to the sensor for monitoring the sensor temperature.
