Abstract:
A semiconductor structure includes an oxide ReRAM co-integrated with a drain region of a field effect transistor (FET). The oxide ReRAM has a tip region defined by a pointed cone that contacts a faceted upper surface of the drain region of the FET. Such a tip region enhances the electric field of the oxide ReRAM and thus helps to control forming of the conductive filament of the oxide ReRAM.

Claim (Index 21):
A method of forming a semiconductor structure, the method comprising:\n providing a sacrificial gate structure on a surface of a semiconductor substrate, wherein a first dielectric spacer and a second dielectric spacer laterally surround the sacrificial gate structure; forming a source region and a drain region in the semiconductor substrate and on opposite sides of the sacrificial gate structure, wherein the source region and the drain region have faceted sidewall surfaces; performing a self-limiting etch of the drain region to provide a faceted upper surface to the drain region; and forming elements of an oxide resistive random access memory (ReRAM) device in contact with the faceted upper surface of the drain region, wherein the forming of the ReRAM device comprises forming at least a resistive switching layer and a top electrode material, and recessing the resistive switching layer and the top electrode material.
