Abstract
In some embodiments, the present disclosure relates to a method of forming a metal-insulator-metal (MIM) device. The method may be performed by depositing a bottom electrode layer over a substrate, depositing a dielectric layer over the bottom electrode layer, depositing a top electrode layer over the dielectric layer, and depositing a first titanium getter layer over the top electrode layer. The first titanium getter layer, the top electrode layer, and the dielectric layer are patterned to expose a peripheral portion of the bottom electrode layer. A passivation layer is deposited over the substrate, the first titanium getter layer, and the peripheral portion of the bottom electrode layer.
