摘要： A method of electrically linking the 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： Disclosed is an improved CMOS fabrication method that allows an implanted well in a bare silicon wafer to be simultaneously, driven annealed and denuded in a single process step. More specifically, a single step drive-anneal-denude (DAD) process is accomplished using a non-inert ambient environment. The DAD process is accomplished in a combination argon/hydrogen ambient environment. This process causes the silicon wafer to roughen slightly and is followed by an oxidation step, that optionally takes place in a combination argon/oxygen ambient environment to smooth out the silicon surface. The oxidation step may also optionally act as a pad-oxide or screening oxide for subsequent fabrication.

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： Described herein is a reference voltage circuit which includes, in combination, a bit line and first and second word line reference transistors connected to the bit line and operative to be turned on with a reference pulse simultaneously with the turning on of the word lines in the main memory circuit. First and second ferroelectric capacitors are connected to each of the first and second word line reference transistors, respectively, and to a source of plate line switching voltage, and a first precharging transistor is connected between the first ferroelectric capacitor and ground potential. A second precharging transistor is connected between the second ferroelectric capacitor and a further source of switching voltage, so that the first and second ferroelectric capacitors are polarized in a ONE and ZERO state in the manner identical to the logic states of the ferroelectric capacitors in the main ferroelectric memory circuit. Thus, when the first and second word line reference transistors turn on, the bit line reference voltage is raised above ground potential by the sum of the voltages of the first and second ferroelectric capacitors. This in turn causes the bit line reference voltage, BL, to track the voltage variations of the ferroelectric capacitors in the main memory circuit, thus providing improved margins for the BL and BL complementary signals which are sensed by a plurality of sense amplifiers for the main memory circuit.
