Abstract

A two-terminal resistive switching device (TTRSD) such as a non-volatile two-terminal memory device or a volatile two-terminal selector device can be formed according to a manufacturing process. The process can include forming an etch stop layer that is made of aluminum and can include forming a buffer layer below the etch stop layer and/or between the etch stop layer and a top electrode of the TTRSD.
