Abstract

We developed the new control gate (CG) material and structure in order to overcome scaling limitation beyond 20nm NAND flash cell. New CG material can achieve excellent gap-fill without void and improvement of the Gate CD Gap (GCG). And also, by using new CG material, CG depletion between floating gate (FG) can be improved. As a result, gate coupling ratio, bit-line (BL) interference and tail-cell Vt distribution are drastically improved. These technologies play an important role in the characteristic of scaled NAND flash memory cell and reliability. [ABSTRACT FROM PUBLISHER]
