Claim Text:
1. A method comprising: depositing a first photoresist layer having a first thickness above a substrate; defining a first opening in the first photoresist layer by exposing the first photoresist layer to radiation, the first opening having a first width; depositing a conformal passivation layer directly on the first photoresist layer; depositing a second photoresist layer having a second thickness on the conformal passivation layer; defining a second opening in the second photoresist layer by exposing the second photoresist layer to radiation, the second opening having a second width greater than the first width; depositing a conformal dielectric layer directly on the second photoresist layer and above the first photoresist layer; depositing a metal layer above the first photoresist layer and the substrate to form an electrode, a dielectric layer being provided to contact the metal layer; and removing the first photoresist layer and the second photoresist layer, wherein the first photoresist layer comprises a positive photoresist, and wherein depositing the metal layer comprises depositing a metal layer directly on the conformal dielectric layer, and the conformal passivation layer comprises an inorganic oxide layer.
