A capacitor structure including a silicon material layer, a support frame layer, and a capacitor is provided. The support frame layer is disposed in the silicon material layer. The support frame layer has recesses. There is a cavity between two adjacent recesses. The support frame layer is located between the cavity and the recess. The support frame layer has a through hole directly above the cavity. The capacitor is disposed in the silicon material layer. The capacitor includes a first insulating layer and a first electrode layer. The first insulating layer is disposed on the support frame layer. The first electrode layer is disposed on the first insulating layer and fills the recess and the cavity.

Capacitor structure and manufacturing method thereof

A method of manufacturing a through silicon via (TSV) is provided in the present invention, including steps of forming a TSV sacrificial structure in a substrate, wherein the TSV sacrificial structure contacts a metal interconnect on the front side of the substrate, performing a backside thinning process to expose the TSV sacrificial structure from the back side of the substrate, removing the TSV sacrificial structure to form a through silicon hole, and filling the through silicon hole with conductive material to form a TSV.
