Claim:
1. A method of fabricating an array of electrostatic transfer heads comprising: forming an array of mesa structures on a base substrate, each mesa structure including sidewalls; forming a passivation layer over the base substrate and the array of mesa structures, wherein forming the passivation over the base substrate and the array of mesa structures comprises a technique selected from the group consisting of conformal deposition of the passivation layer over the base substrate and the array of mesa structures and growing the passivation layer over the base substrate and the array of mesa structures; forming a separate electrode directly on the passivation layer and over each corresponding mesa structure such that each electrode is electrically insulated from each corresponding mesa structure; and depositing a dielectric layer over the array of mesa structures and each electrode.
