Abstract
A capacitor including a first and second component capacitor structure disposed on a substrate. A component capacitor structure includes an upright arm, a transverse arm, and a via. The upright arm has a top end and a bottom end that extend at substantially right angles to a central axis of the upright arm. The transverse arm has a left and right end that extend at substantially right angles to a central axis of the transverse arm. The upright arm and the transverse arm intersect to form a cross-like pattern and the top, bottom, left and right ends all extend in the same rotary direction. The via is electrically coupled to an area of intersection of the upright and transverse arms.
