Abstract
Devices and/or methods that facilitate forming a resistive memory crossbar array with a multilayer hardmask are provided. In some embodiments, a resistive random access memory (RRAM) can comprise a multilayer hardmask comprising three layers, an interlayer oxide between a first layer of silicon nitride and a second layer of silicon nitride. In other embodiments, an RRAM can comprise a multilayer hardmask comprising two layers, a layer of an oxide on a layer of silicon nitride.
