Abstract

A method for manufacturing an RRAM cell includes providing a metal-insulator-metal stack and exposing a subsection of a MIM stack to particle bombardment and/or radiation. Exposing a subsection of the MIM stack to particle bombardment and/or radiation forms localized defects in the functional layer of the MIM stack, thereby reducing the required forming voltage of the RRAM cell and further providing precise control over the location of a conductive filament created in the MIM stack during forming of the device.
