摘要： A flat panel display, such as a Field Emission Display (“FED”), is disclosed having a current control circuit. Input into the display, initially, is an analog signal having an amplitude. In one embodiment, the current control circuit includes a converter for converting the analog input signal to a sawtooth signal having a height and width. Then, the level of the sawtooth signal is compared to a voltage level to establish a pulse width of an emitter current. The emitter current is thus controlled by a pulse width modulation approach. In another embodiment, the current control circuit traps a column voltage on a parasitic capacitance. The trapped voltage then controls the gate of a transistor to control current flow from the emitter set to ground.

摘要： Semiconductor structures and methods of making a vertical diode structure are provided. The vertical diode structure may have associated therewith a diode opening extending through an insulation layer and contacting an active region on a silicon wafer. A titanium silicide layer may be formed over the interior surface of the diode opening and contacting the active region. The diode opening may initially be 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 may be heavily doped with a first type dopant and a bottom portion that may be lightly doped with a second type dopant. The top portion may be bounded by the bottom portion so as not to contact the titanium silicide layer. In 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.

摘要： A method of electrically linking contacts of a semiconductor device to their corresponding digit lines. The method includes disposing a quantity of mask material into a trench through which the contact is exposed. The mask also abuts a connect region of a conductive element of a corresponding digit line and, therefore, protrudes somewhat over a surface of the semiconductor device. A layer of insulative material is disposed over the semiconductor device with the mask material being exposed therethrough. The mask material is then removed, leaving open cavities that include the trench and a strap region continuous with the trench and with a connect region of the corresponding digit line. Conductive material is disposed within the cavity and electrically isolated from conductive material disposed in adjacent cavities, which define conductive plugs or studs and conductive straps from the conductive material. These plugs or studs and straps provide an electrically conductive link between each contact of the semiconductor device and its corresponding digit line. Semiconductor devices that include features that have been fabricated in accordance with the method of the present invention are also within the scope of the present invention.

摘要： A contact structure is provided incorporating an amorphous titanium nitride barrier layer formed via low-pressure chemical vapor deposition (LPCVD) utilizing tetrakis-dialkylamido-titanium, Ti(NMe2)4, as the precursor. The contact structure is fabricated by etching a contact opening through a dielectric layer down to a diffusion region to which electrical contact is to be made. Titanium metal is deposited over the surface of the wafer so that the exposed surface of the diffusion region is completely covered by a layer of the metal. At least a portion of the titanium metal layer is eventually converted to titanium silicide, thus providing an excellent conductive interface at the surface of the diffusion region. A titanium nitride barrier layer is then deposited using the LPCVD process, coating the walls and floor of the contact opening. Chemical vapor deposition of polycrystalline silicon or of a metal follows.
