Abstract

Platinum-aluminum (Pt-Al) alloy top electrode on the retention improvement of gadolinium oxide (GdxOy) resistive switching memory was investigated. The aluminum oxide (AlxOy) formation at the Pt-Al alloy top electrode and GdxOy interface will lead to the high Schottky barrier height. Further, the more aluminum incorporation can suppress the crystallization of platinum electrode after the post-metallization annealing. Both the crystallization suppression of Pt top electrode and the interfacial aluminum oxide formation will prevent the oxygen ions from out-diffusion through Pt grain boundaries, responsible for the retention enhancement of the GdxOy resistive switching memory.
