    Abstract: A metal-insulator-metal (MIM) capacitor structure and a method for manufacturing the same. The method includes a step hereinafter. A 5-layered dual-dielectric structure is provided on a substrate. The 5-layered dual-dielectric structure includes a bottom metal layer, a first dielectric layer, an intermediate metal layer, a second dielectric layer and a top metal layer in order. The first dielectric layer and the second dielectric layer have different thicknesses.
