Abstract
A capacitor structure is provided. The capacitor structure is configured in a substrate. The capacitor structure includes a plurality of electrode sets, at least a first conductive plug and at least a second conductive plug. The electrode sets correspond with each other and are disposed in different layers of the substrate. Each electrode set comprises a first electrode and a second electrode surrounding the former. In addition, the first conductive plug and the second conductive plug are disposed between two adjacent electrode sets. First electrodes of two adjacent electrode sets correspond with each other and are electrically connected to each other through the first conductive plug. Similarly, second electrodes of two adjacent electrode sets correspond with each other and are electrically connected to each other through the second conductive plug.
