MIM capacitor and metal interconnection

摘要

Disclosed are an MIM (Metal-Insulator-Metal) capacitor and a method of manufacturing the same. The MIM capacitor includes: a lower metal layer and a lower metal interconnection on a substrate; a barrier metal layer on the lower metal layer; an insulating layer on the barrier metal layer; an upper metal layer on the insulating layer; an interlayer dielectric layer having a via hole on the lower metal interconnection; and a plug in the via hole.
