    摘要: Some embodiments include memory cells having vertically-stacked charge-trapping zones spaced from one another by dielectric material. The dielectric material may comprise high-k material. One or more of the charge-trapping zones may comprise metallic material. Such metallic material may be present as a plurality of discrete isolated islands, such as nanodots. Some embodiments include methods of forming memory cells in which two charge-trapping zones are formed over tunnel dielectric, with the zones being vertically displaced relative to one another, and with the zone closest to the tunnel dielectric having deeper traps than the other zone. Some embodiments include electronic systems comprising memory cells. Some embodiments include methods of programming memory cells having vertically-stacked charge-trapping zones.

    摘要: Methods for fuming dielectric layers over polysilicon substrates, useful in the construction of capacitors and other semiconductor circuit components are provided. A self-limiting nitric oxide (NO) anneal of a polysilicon layer such as an HSG polysilicon capacitor electrode, at less than 800° C., is utilized to grow a thin oxide (oxynitride) layer of about 40 angstroms or less over the polysilicon layer. The NO anneal provides a nitrogen layer at the polysilicon-oxide interface that limits further oxidation of the polysilicon layer and growth of the oxide layer. The oxide layer is exposed to a nitrogen-containing gas to nitridize the surface of the oxide layer and reduce the effective dielectric constant of the oxide layer. The process is particularly useful in forming high K dielectric insulating layers such as tantalum pentoxide over polysilicon. The nitridized oxynitride layer inhibits oxidation of the underlying polysilicon layer in a post-treatment oxidizing anneal of the high K dielectric, thus maintaining the oxide layer as a thin layer over the polysilicon layer.

    摘要: The present disclosure describes apparatus and methods for processing microfeature workpieces, e.g., by depositing material on a microelectronic semiconductor using atomic layer deposition. Some of these apparatus include microfeature workpiece holders that include gas distributors. One exemplary implementation provides a microfeature workpiece holder adapted to hold a plurality of microfeature workpieces. This workpiece holder includes a plurality of workpiece supports and a gas distributor. The workpiece supports are adapted to support a plurality of microfeature workpieces in a spaced-apart relationship to define a process space adjacent a surface of each microfeature workpiece. The gas distributor includes an inlet and a plurality of outlets, with each of the outlets positioned to direct a flow of process gas into one of the process spaces.

    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.
