ABSTRACT:
A capacitor that is adapted for construction over a substrate in the metal interconnect layers provided by conventional integrated circuit processes. The capacitor includes a first conducting layer separated from the substrate by a first dielectric layer and a second conducting layer separated from the first conduction layer by a second dielectric layer. The second conducting layer is divided into a plurality of electrically isolated conductors in an ordered array. Every other one of the conductors is connected to a first terminal, and the remaining conductors are connected to a second terminal. The first conducting layer includes at least one conductor which is connected to the first terminal. In one embodiment of the invention, the first conducting layer also includes a plurality of electrically isolated conductors in an ordered array, every other one of the conductors being connected to the first terminal and the remaining conductors being connected the second terminal.
