    摘要: A memory device (100) may include a substrate (110), a dielectric layer (210) formed on the substrate (110) and a charge storage element (220) formed on the dielectric layer (210). The memory device (100) may also include an inter-gate dielectric (230) formed on the charge storage element (220), a barrier layer (240) formed on the inter-gate dielectric (230) and a control gate (250) formed on the barrier layer (240). The barrier layer (240) prevents reaction between the control gate (250) and the inter-gate dielectric (230).

    摘要: Methods for fabricating a flash memory device are provided. A method comprises forming a plurality of gate stacks overlying a substrate. Each gate stack comprises a charge trapping layer and a control gate. The control gate is a first distance from the substrate. Adjacent gate stacks are a second distance apart. A cell spacer material layer is deposited and is etched to form a spacer about sidewalls of each gate stack. A source/drain impurity doped region is formed adjacent a first gate stack and a last gate stack. The first distance and the second distance are such that, when a voltage is applied to a gate stack during a READ operation, a fringing field is created between the control gate of the gate stack and the substrate and is sufficient to invert a portion of the substrate between the gate stack and an adjacent gate stack.
