ABSTRACT:
A capacitor structure including a conductive layer and a dielectric layer is provided. The conductive layer includes a first pattern and a second pattern arranged alternatively with respect to each other. In addition, the dielectric layer is disposed between the first spiral pattern and the second spiral pattern. Since in the capacitor structure described in the present invention, the first pattern and the second pattern being used as electrodes are disposed in a spiral shape, the capacitance per unit area of the capacitor structure is increased.
