摘要:
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.
