    Abstract: A method for fabricating a memory device with a self-aligned trap layer which is optimized for scaling is disclosed. In the present invention, a non-conformal oxide is deposited over the charge trapping layer to form a thick oxide on top of the core source/drain region and a pinch off and a void at the top of the STI trench. An etch is performed on the pinch-off oxide and the thin oxide on the trapping layer on the STI oxide. The trapping layer is then partially etched between the core cells. A dip-off of the oxide on the trapping layer is performed. And a top oxide is formed. The top oxide converts the remaining trap layer to oxide and thus isolate the trap layer.

    Abstract: An embodiment of the present invention is directed to a method of forming a memory cell. The method includes etching a trench in a substrate and filling the trench with an oxide to form a shallow trench isolation (STI) region. A portion of an active region of the substrate that comes in contact with the STI region forms a bitline-STI edge. The method further includes forming a gate structure over the active region of the substrate and over the STI region. The gate structure has a first width substantially over the center of the active region of the substrate and a second width substantially over the bitline-STI edge, and the second width is greater than the first width.
