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.

摘要： A flash memory integrated circuit and a method for fabricating the same. A gate stack includes an initial oxide layer directly in contact with a silicon layer, defining an oxide-silicon interface therebetween. Additional oxide material is formed substantially uniformly along the oxide-silicon interface. Polysilicon grain boundaries at the interface are thereby passivated after etching. The interface can be is formed between a tunnel oxide and a floating gate, and passivating the grain boundaries reduces erase variability. Oxide in an upper storage dielectric layer is enhanced in the dilute steam oxidation. The thin oxide layers serve as diffusion paths to enhance uniform distribution of OH species across the buried interfaces being oxidized.

摘要： The present invention provides a flash memory integrated circuit and a method for fabricating the same. The method includes etching a gate stack that includes an initial oxide layer directly in contact with a silicon layer, defining an oxide-silicon interface therebetween. By exposing the etched gate stack to elevated temperatures and a dilute steam ambient, additional oxide material is formed substantially uniformly along the oxide-silicon interface. Polysilicon grain boundaries at the interface are thereby passivated after etching. In the preferred embodiment, the interface is formed between a tunnel oxide and a floating gate, and passivating the grain boundaries reduces erase variability due to enhanced charge transfer along grain boundaries. At the same time, oxide in an upper storage dielectric layer (oxide -nitride-oxide or ONO) is enhanced in the dilute steam oxidation. Thermal budget can be radically conserved by growing thin oxide layers on either side of a nitride layer prior to etching, and enhancing the oxide layers by dilute steam oxidation through the exposed sidewall after etching. The thin oxide layers, like the initial tunnel oxide, serve as diffusion paths to enhance uniform distribution of OH species across the buried interfaces being oxidized.
