    摘要: A method of fabricating a memory device having a core region of double-bit memory cells and a periphery region of logic circuitry includes forming a dielectric stack over the core and periphery areas of a semiconductor substrate and removing the dielectric stack from the periphery region. A gate dielectric is formed over the periphery area, followed by a first conductive layer over the core and periphery areas. After the formation and thermal processing of the gate dielectric, bitlines, which serve as source and drain regions, are implanted into the core area. Formation of the bitlines after the gate dielectric layer reduces lateral bitline diffusion and reduces short channel effects.

    摘要: A memory and method of manufacture employing word line scaling. A layered stack, including a charge trapping component and a core polysilicon layer, is formed on a core section and a peripheral section of a substrate. A portion of the layered stack, including the core polysilicon layer is then removed from the peripheral section. A peripheral polysilicon layer, which is thicker than the core polysilicon layer of the layered stack, is next formed on the layered stack and the peripheral section. The layered stack is then isolated from the peripheral polysilicon layer by removing a portion of the peripheral polysilicon layer from the core section, and polysilicon lines are patterned in the isolated layered stack.

    摘要: A memory cell with reduced short channel effects is described. A trench region is formed in a semiconductor substrate. A source region and a drain region are formed on opposing sides of the trench region, wherein a bottom of the source region and a bottom of the drain region are above a floor of the trench region. A gate dielectric layer is formed in the trench region of the semiconductor substrate between the source region and the drain region. A recessed channel region is formed below the trench region, the source region and the drain region. A control gate is formed on the semiconductor substrate above the recessed channel region, wherein the control gate is separated from the recessed channel region by the gate dielectric layer.
