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 11):
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, wherein an interlayer dielectric (ILD) material layer protects the source region during the performing of the self-limiting etch; and forming elements of an oxide resistive random access memory (ReRAM) device in contact with the faceted upper surface of the drain region.
