Method of fabricating non-volatile memory device
Abstract:
A method of fabricating a non-volatile memory is provided. A tunneling dielectric layer and a first patterned conductive layer are sequentially formed on a substrate. A patterned inter-gate dielectric layer and a second patterned conductive layer are stacked on a first surface of the first patterned conductive layer, and a second surface of the first patterned conductive layer is exposed. The second surface is adjacent to the first surface. The substrate is covered by a passivation layer, and a first sidewall of the first patterned conductive layer is exposed. A recess is formed on the first sidewall of the first patterned conductive layer, such that the first sidewall has a sharp corner. A portion of the passivation layer on the second surface is removed, such that the sharp corner of the first patterned conductive layer is exposed.
