    摘要: Thin film transistor memory cells are stackable, and employ bandgap engineered tunneling layers in a junction free, NAND configuration, that can be arranged in 3D arrays. The memory cells have a channel region in a semiconductor strip formed on an insulating layer, a tunnel dielectric structure disposed above the channel region, the tunnel dielectric structure having a multilayer structure including at least one layer having a hole-tunneling barrier height lower than that at the interface with the channel region, a charge storage layer disposed above the tunnel dielectric structure, an insulating layer disposed above the charge storage layer, and a gate electrode disposed above the insulating layer.

    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.
