  • Patent number: 6812521
    Abstract: Dopant of an n-type is deposited in the channel area of a p-type well of isolated gate floating gate NMOS transistors forming the memory cells of a memory device array connected in a NAND gate architecture. The dopant is provided by a tilt angle around the existing floating gate/control gate structure at the stage of the fabrication process where the floating gate/control structure is in existence, the field oxidation step may also have occurred, and implantation of the source and drain dopants may also have occurred. This forms a retrograde n-type distribution away from the direction of the surface of the substrate in the channel, which is also concentrated laterally toward the centerline axis of the gate structure and decreases towards the opposing source and drain regions. This deposition promotes buried-channel-like performance of the NMOS transistors connected in series in the NAND gate memory architecture.

  • Patent number: 6281078
    Abstract: Polystringers that cause NAND-type memory core cells to malfunction are covered by ONO fence material. ONO fence is removed so that polystringers may then be removed more readily. A SiON layer, tungsten silicide layer, second polysilicon layer, ONO dielectric, and first polysilicon layer are successively removed from between NAND-type flash memory core cells leaving ONO fence that shields some first polysilicon layer material from removal. The device is next exposed to an hydrogen-fluoride solution to remove oxide-based materials, particularly ONO fence. Thereafter, the polystringers are exposed and may thus be removed more readily.

  • Patent number: 6114230
    Abstract: A polysilicon-based floating gate is formed so as to be resistant to oxidation that occurs during multiple thermo-cycles in fabrication. Accordingly, edge erase times in NOR-type memory devices may be minimized. Additionally, manufacture of oxidation resistant floating gates reduces variations in edge erase times among multiple NOR-type memory devices. A layer of amorphous silicon is deposited over a silicon substrate by directing a mixture of silane and a phosphene-helium gas mixture at the surface of the silicon substrate. Later, N+ ions are implanted into the amorphous silicon. The amorphous silicon layer is then etched so as to overlap slightly with regions that will later correspond to the source and drain regions. Next, a lower oxide layer of an ONO dielectric is deposited and the device is heated. A thermo-cycle is eliminated by heating the amorphous silicon during formation of the oxide layer rather than immediately following its deposition.

  • Patent number: 6063668
    Abstract: A layer of polysilicon is deposited over an oxide layer on top of a silicon substrate, with core field oxide and active regions, and patterned. An oxide mask is then added. Next, the oxide mask and the layer of polysilicon are removed from above the core field oxide regions. Next, a second layer of polysilicon is deposited and etched to form polysilicon spacers. Later, an ONO dielectric, a third polysilicon layer, a tungsten silicide layer, and SiON layers are successively formed and patterned. The polysilicon spacers effectively seal any recesses that may occur in the edges of the first polysilicon layer to prevent harboring of subsequently added polysilicon material. Accordingly, NAND-type flash memory core cells cannot be electrically shorted by polysilicon material, so called "polystringers", present in such recesses.
