摘要： An injection method for non-volatile memory cells with a Schottky source and drain is described. Carrier injection efficiency is controlled by an interface characteristic of silicide and silicon. A Schottky barrier is modified by controlling an overlap of a gate and a source/drain and by controlling implantation, activation and/or gate processes.

摘要： A method of manufacturing a non-volatile semiconductor memory device includes forming a sub-gate without an additional mask. A low word-line resistance is formed by a metal silicide layer on a main gate of the memory device. In operation, application of a voltage to the sub-gate forms a transient state inversion layer that serves as a bit-line, so that no implantation is required to form the bit-line.
