Abstract: Arrangement of nanowires with PN junctions between bit lines and word lines are arranged as a ROM memory cell array. A number of the nanowires have dielectric regions and are present only as a dummy. The connections between word and bit lines may also exist as transistors which turn on or turn off only when a gate voltage is applied. A number of these transistors are constructed in complementary fashion and/or have insulating regions built in and serve as a dummy.

Abstract: Regio-regular polythiophenes used in diodes which are not light emitting or photovoltaic. High quality, processable thin film polymer films can be made. The thin film can have a thickness of about 50 nm to about one micron, and the conductive thin film can be applied by spin casting, drop casting, screening, ink-jetting, transfer or roll coating. The polythiophenes can be homopolymers or copolymers. The regio-regular poly(3-substitutedthiophene) can be derivatized so that the 3-substituent is an alkyl, aryl, or alkyl/aryl moiety with a heteroatom substitution in either the ?- or beta-position of the 3-substituent.

The ESD protection circuit includes a first bipolar transistor having an emitter coupled to the first pad. A second bipolar transistor having a base and a collector coupled to the second pad is used. Zero or more bipolar transistors are sequentially coupled between the first and second bipolar transistors in a base-to-emitter manner. A collector of the first bipolar transistor and the sequentially coupled transistors is connected to a base of a subsequently coupled bipolar transistor for helping to turn on the first, second and sequentially coupled bipolar transistors to provide a current path from the first pad to the second pad during an ESD event.

Abstract: A method of making a vertical diode structure is provided, the vertical diode structure having associated therewith a diode opening extending through an insulation layer and contacting an active region on a silicon wafer. A titanium silicide layer covers the interior surface of the diode opening and contacts the active region. The diode opening is initially filled with an amorphous silicon plug that is doped during deposition and subsequently recrystallized to form large grain polysilicon. The silicon plug has a top portion that is heavily doped with a first type dopant and a bottom portion that is lightly doped with a second type dopant. The top portion is bounded by the bottom portion so as not to contact the titanium silicide layer. For one embodiment of the vertical diode structure, a programmable resistor contacts the top portion of the silicon plug and a metal line contacts the programmable resistor.

The programmable element can be used to form a programmable array having very low parasitic capacitance, enabling the realization of a large and ultra fast programmable logic array.

The system includes an ESD protection circuit having one or more first diodes coupled in series between the supply voltage and terminal pad, and a second diode coupled to ground. One or more third diodes are coupled in series between the terminal pad and second diode, and are configured to permit a voltage on the interconnection nodes between the one or more third diodes and second diode different from ground. The one or more third diodes include an n+ on an area of P-substrate. A deep N-well separates the area of P-substrate from a common area of P-substrate, which is coupled to ground. The allowable signal swing at the terminal pad is increased to greater than supply voltage plus 1.4 V. The ESD protection circuit is useful for, among other things, relatively low supply voltage ICs.

As a result, a structure of the device is simplified, and the device may be highly integrated due to repeated stacking.

Abstract: A ground shield for an integrated component device to prevent coupling between integrated capacitors and/or inductors and other integrated components. Components are formed upon a substrate. A conductive metal layer is formed or deposited thereon. The conductive metal layer is electrically connected to ground and an isolation layer is formed or deposited upon the conductive metal layer. An integrated capacitor, for example a MIM-type capacitor, is then formed upon the isolation layer. The grounded conductive metal layer absorbs electrical noise such that coupling between the capacitor and other components is prevented.
