摘要:
A method used during the formation of a semiconductor device comprises providing a wafer substrate assembly comprising a plurality of digit line plug contact pads and capacitor storage cell contact pads which contact a semiconductor wafer. A dielectric layer is provided over the wafer substrate assembly and etched to expose the digit line plug contact pads, and a liner is provided in the opening. A portion of the digit line plug is formed, then the dielectric layer is etched again to expose the capacitor storage cell contact pads. A capacitor bottom plate is formed to contact the storage cell contact pads, then the dielectric layer is etched a third time using the liner and the bottom plate as an etch stop layer. A capacitor cell dielectric layer and capacitor top plate are formed which provide a double-sided container cell. An additional dielectric layer is formed, then the additional dielectric layer, cell top plate, and the cell dielectric are etched to expose the digit line plug portion. Finally, a second digit line plug portion is formed to contact the first plug portion. A novel structure resulting from the inventive method is also discussed.

An electronic interactive communication system and method is disclosed. Software controls and a control manager resides on a unit that communicates with a central location. The central location transmits information to the unit. The information, or data, may reside in a database at the central location. A number of different units receive data from the central location's transmission source to update or manipulate data already on the units. The system exchanges data from the units to the central location using a narrow bandwidth. The unit includes a transceiver and a processor. The unit also includes a display to display the data to the user after the received data has been associated with the stored data. For example, received data is overlaid on a map being displayed on the unit.

A dynamic graphical information presentation is generated and overlaid onto a time-lapse video image sequence to form a combined graphical information and time-lapse photography presentation. The time-lapse photography video image sequence and dynamic graphical information presentation are preferably time synchronized in the combined presentation. For a weather presentation of past weather conditions, the time-lapse photography video image sequence may be a video image sequence of sky conditions, with the dynamic graphical information presentation generated based on weather conditions recorded for the same period of time from a weather information source. For a presentation of forecast weather conditions, the time-lapse photography video image sequence may be selected from a database of stored pre-recorded sequences, with the dynamic graphical information presentation derived from forecast weather condition information.

Electrode structures, variable resistance memory devices, and methods of making the same, which minimize electrode work function variation. Methods of forming an electrode having a minimized work function variation include methods of eliminating concentric circles of material having different work functions. Exemplary electrodes include electrode structures having concentric circles of materials with different work functions, wherein this difference in workfunction has been minimized by recessing these materials within an opening in a dielectric and forming a third conductor, having a uniform work function, over said recessed materials.

An improved surface P-channel transistor includes providing a semiconductor substrate, forming a gate oxide layer over the semiconductor substrate, subjecting the gate oxide layer to a remote plasma nitrogen hardening treatment followed by an oxidative anneal, and forming a polysilicon layer over the resulting gate oxide layer. Significantly, the present invention does not require nitrogen implantation through the polysilicon layer overlying the gate oxide and provides a surface P-channel transistor having a polysilicon electrode free of nitrogen and a hardened gate oxide layer characterized by a large concentration of nitrogen at the polysilicon electrode/gate oxide interface and a small concentration of nitrogen at the gate oxide/semiconductor substrate interface. The present invention is easily incorporated into fabrication processes and provides an enhanced surface P-channel transistor that resists hot electron degradation, is substantially impermeable to dopants included in overlying layers, and is characterized by a greatly increased extrapolated time dependent dielectric breakdown value.
摘要:
A variable resistance memory sense amplifier has a built-in offset to assist in switching the sense amplifier when a resistive memory cell is in a low resistance state. The built-in offset can be achieved by varying size, threshold voltage, associated capacity or associated resistance of the transistors within the sense amplifier.
摘要:
A system and method for generating weather reports and the like which are precisely computed automatically for a particular individual user's geographic location and which are provided automatically to the individual user. A user establishes an individualized user profile in which the user defines a particular location of interest, a contact address, and optionally, a personalized activity weather condition profile, establishing a preferred weather condition profile for activities of interest. A detailed and accurate weather forecasting model is run to provide high geographical and temporal resolution forecast data. The resulting modeled forecast data may be constrained by an operator using a constrainer module. The high resolution forecast data is compared to the individual user profile and personalized weather report for the particular location, times, and conditions of interest are provided automatically to the individual, e.g., via e-mail and/or at a personalized internet web page. A detailed weather forecast report may be provided in an easily readable tabular form, with notable weather conditions, e.g., daily high and low temperatures, highlighted. The high resolution forecast data may be generated locally for a limited region, e.g., at a television station for the station's viewing area, using initialization conditions provided from a central location, and/or for a wider region, e.g., the entire country, using a less high resolution weather forecast module.
