Abstract
An integrated circuit capacitor ( ) uses multiple electrically conductive stacks ( ) to optimize capacitance density. A second stack ( ) is a first nearest neighbor to a first stack ( ). A third stack ( ) is a second nearest neighbor to the first stack. Each of the three stacks defines vertices of an isosceles triangle ( ) formed in a plane substantially perpendicular to the three stacks. The isosceles triangle does not have a ninety degree angle. The isosceles triangle may also be implemented as an equilateral triangle.
