摘要： 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.

摘要： Embodiments of the present invention disclose a memory device having an array of flash memory cells with source contacts that facilitate straight word lines, and a method for producing the same. The array is comprised of a plurality of non-intersecting shallow trench isolation (STI) regions that isolate a plurality of memory cell columns. A source column is implanted with n-type dopants after the formation of a tunnel oxide layer and a first polysilicon layer. The implanted source column is coupled to a plurality of common source lines that are coupled to a plurality of source regions associated with memory cells in the array. A source contact is coupled to the implanted source column for providing electrical coupling with the plurality of source regions. The source contact is collinear with a row of drain contacts that are coupled to drain regions associated with a row of memory cells. The arrangement of source contacts collinear with the row of drain contacts allows for straight word line formation.
