Abstract: A method for fabricating a floating gate memory device comprises using self-aligned process for formation of a fourth poly layer over a partial gate structure that does not require an additional photolithographic step. Accordingly, enhanced device reliability can be achieved because a higher GCR can be maintained with lower gate bias levels. In addition, process complexity can be reduced, which can increase throughput and reduce device failures.
