Abstract:
A self-aligned 1 bit silicon oxide nitride oxide silicon (SONOS) cell and a method of fabricating the same has high uniformity between adjacent SONOS cells, since the lengths of nitride layers do not vary due to misalignment when etching word lines of the 1 bit SONOS cells. An insulating layer pattern that forms a sidewall of a word line is formed on a semiconductor substrate, and a word line for a gate is formed on the sidewall thereof. Etching an ONO layer using a self-aligned etching spacer provides uniform adjacent SONOS cells.
