Patent number: 9997700Abstract: 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.Type: GrantFiled: May 1, 2014Date of Patent: June 12, 2018Assignee: Carnegie Mellon UniversityInventors: Mohamed Abdeltawab Abdelmoula, Marek Skowronski, Abhishek A.

Patent number: 9991330Abstract: The present application provides planar and stacked resistor structures that are embedded within an interconnect dielectric material in which the resistivity of an electrical conducting resistive material or electrical conducting resistive materials of the resistor structure can be tuned to a desired resistivity during the manufacturing of the resistor structure. Notably, a doped metallic insulator layer is formed atop a substrate. A controlled surface treatment process is then performed to an upper portion of the doped metallic insulator layer to convert the upper portion of the doped metallic insulator layer into an electrical conducting resistive material layer. The remaining doped metallic insulator layer and the electrical conducting resistive material layer are then patterned to provide the resistor structure.Type: GrantFiled: January 11, 2017Date of Patent: June 5, 2018Assignee: International Business Machines CorporationInventors: Daniel C.
