SiC-Si3N4 Nanolaminates as a Semiconductor for MSM Snapback Selector Devices

Abstract

Selector elements that can be suitable for nonvolatile memory device applications are disclosed. The selector element can have low leakage currents at low voltages to reduce sneak current paths for non selected devices, and higher leakage currents at higher voltages to minimize voltage drops during device switching. The selector element can be based on multilayer film stacks (e.g. metal-semiconductor-metal (MSM) stacks). The semiconductor layer of the selector element can include a silicon carbide/silicon nitride nanolaminate stack. The semiconductor layer of the selector element can include a silicon carbon nitride/silicon nitride nanolaminate stack. Conductive materials of the MSM may include tungsten, titanium nitride, carbon, or a combination thereof.
