    摘要: A method of fabricating semiconductor devices with a passivated surface includes providing a contact layer on a substrate so as to define an inter-electrode surface area. A first layer and an insulating layer, which are selectively etchable relative to each other and to the substrate and the contact layer, are deposited on the contact layer and the inter-electrode surface area. The insulating layer and the first layer are individually and selectively etched to define an electrode contact area and to expose the inter-electrode surface area. The exposed inter-electrode surface area is passivated, either subsequent to or during the etching of the first layer. A metal contact is formed in the electrode contact area in abutting engagement with the insulating layer so as to seal the inter-electrode surface area.

    摘要: The present invention encompasses a complementary semiconductor device having the same type of material providing the ohmic contacts (117, 119) to both the N-type and P-type devices. In a preferred embodiment, P-source and P -drain regions ( 80, 82 ) are heavily doped with a P-type impurity (81, 83) so that an ohmic with N-type impurity can be used as an ohmic contact. One ohmic material that may be used is nickel-germanium-tungsten. Nickel-germanium-tungsten is etchable, and therefore does not require lift-off processing. Furthermore, a preferred complementary semiconductor device made in accordance with the present invention is compatible with modern aluminum based VLSI interconnection processes.

    摘要: A layered bismuth ferroelectric structure (12) and a method for forming the bismuth layered ferroelectric structure (12). A monolayer (12A) of bismuth is formed in intimate contact with a single crystalline semiconductor material (11). A layered ferroelectric material (12) is grown on the monolayer (12A) of bismuth such that the monolayer (12A) of bismuth becomes a part of the layered ferroelectric material (12). The ferroelectric material (12) forms a layered ferroelectric material which is not a pure perovskite, wherein the crystalline structure at the interface between the single crystalline semiconductor material (11) and the monolayer (12A) of bismuth are substantially the same.

    摘要: An input buffer includes an input circuit (80), a pair of complimentary outputs (52,54) and a differential ampliifer (12). The input buffer includes a pull-down diode (90) arranged in parallel with pull-up diodes (84, 86, and 88), coupled between the buffer input (82) and the differential amplifier input (32). Pull-up is achieved through the low impedance path of the pull-up diodes, eliminating a need for a high value resistor. Pull-down is achieved through the pull-down diode in series with a resistor (92). This arrangement provides high speed of operation, while reducing current consumption.

    摘要: A high frequency divider suitable for use in a frequency synthesizer using a dual modulus prescaler and two counters to achieve high speed and low current drain. The input signal is alternately divided by one of the two moduli in the prescaler and then alternately divided by one of the two counters. Each of the two counters is reset while the other is counting thereby reducing circuit complexity and increasing circuit speed.

    摘要: A method of fabricating a field effect transistor including doping a continuous blanket layer in a semiconductor substrate structure adjacent the surface to include a source area and a drain area spaced from the source area. A high dielectric constant insulator layer is positioned on the surface of the semiconductor substrate structure overlying the continuous blanket layer to define a gate area between the source and drain areas. A gate contact on the insulator layer is selected to provide a work function difference that depletes the doped layer beneath the insulator layer. Further, the doped layer depth and dosage are designed such that the doped layer is depleted beneath the insulator layer by the selected work function difference of the gate contact and the semiconductor substrate.

    摘要: A switch network (22) in a Field Programmable Gate Array (FPGA) which operates as a combination of a programming transistor (34) and a ferroelectric transistor (32). The programming transistor (34) is selected to transfer a polarizing voltage to a gate terminal of the ferroelectric transistor (32) for programming the ferroelectric transistor (32) in an on-state. The ferroelectric transistor (32) functions as a nonvolatile latch and pass device to provide the electrical interconnect path that links multiple Configurable Logic Blocks (CLBs). The programming transistor (34) is selected to transfer a depolarizing voltage to the gate terminal of the ferroelectric transistor (32) for programming the ferroelectric transistor (32) in an off-state.
