  • Patent number: 4717681
    Abstract: A wafer process flow encompasses an arbitray repeated layered structure of heteroepitaxial layers of silicon based films with process control throughout the strata of chemical potential and recombination velocity, suitable for both high performance MOS and bipolar transistors with three dimensional transistor capability. A non-compensated doping technique preserves crystalline periodicity, as does the component delineation by means of anisotropic etching. The wafer is hermetic by means of the semi-insulation films polyimide, and the elimination of phosphorous doped silicon dioxide. A metallurgy system enables a high level integration.

  • Patent number: 4704785
    Abstract: A process, and product made thereby, for bonding two wafers together to form a single wafer with a continuous interface, and for selectively burying a low impedance conductor in the wafer, by providing host and guest wafers having substantially the same crystal orientation and periodicity. A crystalline boundary n-semimetal is formed on the wafers, which are then brought into intimate contact. If desired, a unipolar conductor is fused to one of said wafers. Then, the wafers are exposed to an elevated temperature, or rapid thermal anneal, in an inert ambient, breaking up any native oxides and diffusing any excess oxygen into the wafer lattices. The guest wafer is then mechanically lapped back and chemically etched.A vertical cascode integrated half H-bridge motor driving circuit made in the guest and host wafers has a source transistor in the host wafer with with the wafer substrate forming the collector of the transistor, an isotype acceptor doped Ge.sub.x Si.sub.

  • Patent number: 4654514
    Abstract: Individual display modules are located along a shelf containing items for sale. The display modules are loaded via a hand-held unit with data pertaining to the items. This data has previously been downloaded from a host computer into the hand-held unit. In order to minimize human error, the hand-held unit contains a reader for reading a code from either the item or the shelf upon which the item is located. This code is then used by the hand-held unit in order to determine what data is to be downloaded into the appropriate display module. The coupling between the hand-held unit and the display modules may be of the type requiring a direct electrical connection or the close-proximity type employing optical or electro-magnetic coupling.

  • Patent number: 4645881
    Abstract: The method includes generating a binary signal (S4A to S4D) which is time modulated. To do this, an alternating signal (S1) is compared with a known cyclical signal (S5) and a threshold signal. There is measured the durations between the transitions of the modulated signal by means of a high speed clock and by means of counting in the positive and negative directions of the clock pulses for one or more periods of the signal under examination. If, after counting, a residual value is found, one generates a binary signal representing the transition.

  • Patent number: 4604640
    Abstract: In a darlington transistor having an integrated resistor connected from base to emitter of the output transistor element, the effect of the diode between collector and emitter formed when the resistor consists of an extension to the base region is reduced by forming at least part of the resistor either as an extension to the emitter region or as a separate region of the same conductivity type and connected to it. The resistor formed by the emitter region material appears in series with the diode.

  • Patent number: 4535723
    Abstract: An assembly of gates and pens, or other enclosures, for assembling, sorting, holding, and guiding animals to and from one or more processing stations. A plurality of perimeter gates define and enclose a sorting area having a second set of gates which divide the sorting area into separate sections. A number of holding pens, or other enclosures, adjoin the sorting area such that access to the sorting area from each holding pen is provided by a perimeter gate. Animals are guided from a holding pen, through the sorting area, then through a crowding area, then through a lead-up alley which exits back into the sorting area, one section of which is thus used for redirecting processed animals while another section is being used for incoming animals.

  • Patent number: 4531097
    Abstract: A high frequency amplifier comprising a pair of input transistors forming a differential amplifier stage, with an impedance connected between the common terminals of the input transistors to vary the amplification factor of the amplifier stage. The variable impedance is formed by a diode bridge the a.c. terminals of which are connected to the common terminals of the input transistors and the d.c. terminals of which are connected to a circuit arrangement including current mirrors to feed a d.c. current to the diode bridge to control its impedance and hence the amplification factor of the differential amplifier stage.

  • Patent number: 4455738
    Abstract: A MESFET is fabricated using a self-aligned gate process. This process uses a vertical (anisotropic) etch to self-align the gate and source/drain. The vertical etch, in conjunction with a two-level insulator, creates a barrier between the gate and source/drain, so that when metal is deposited and reacted, and any excess removed, the gate is self-aligned with the source/drain, and contacts to the source/drain and gate are well isolated. The alignment obtained by this process is advantageous in that series channel resistance is reduced, and a more compact structure is attained for improvement in packing density.

  • Patent number: 4435785
    Abstract: A non-volatile JRAM cell is constructed to require only positive voltage for programming and erasing of data in the cell. The "well" region of the cell JFET device may be implanted with an impurity concentration that will permit lower breakdown voltage or the non-volatile gate may overlap the JFET gate sufficiently to be able to have the same effect, or some combination of both may be used. This allows the cell to be erased using voltages of one polarity.
