ABSTRACT:
A capacitor is formed in three adjacent conductive layers of a semiconductor integrated circuit chip. A first plate of the capacitor is formed in the middle layer. A second plate is formed in the upper and lower layers plus a small portion of the middle layer which interconnects the upper and lower layers and forms a U-shaped structure surrounding the first plate. These capacitors are preferably formed in pairs with the first plates interconnected. The second plates may be connected to different voltage supplies to form a capacitive voltage divider.
