Abstract: According to one embodiment, a scalable integrated MIM capacitor in a semiconductor die includes a high-k dielectric segment over a substrate and a metal segment over the high-k dielectric segment, where the metal segment forms a capacitor terminal of the integrated MIM capacitor. The capacitor further includes a filler laterally separating consecutive capacitor terminals, where the filler can be used as a capacitor dielectric of the integrated MIM capacitor. In one embodiment, the metal segment comprises a gate metal. In another embodiment, the integrated MIM capacitor is formed substantially concurrently with one or more transistors without requiring additional fabrication process steps.

Abstract: A vertically stacked, planar junction Zener diode is concurrently formed with epitaxially grown FET raised S/D terminals. The structure and process of the Zener diode are compatible with Gate-Last high-k FET structures and processes. Lateral separation of diode and transistor structures is provided by modified STI masking. No additional photolithography steps are required. In some embodiments, the non-junction face of the uppermost diode terminal is silicided with nickel to additionally perform as a copper diffusion barrier.
