Abstract
An improved MOS capacitor array formed on a semiconductor substrate comprises rectangular strips of an active region overlapped by rectangular strips of conductive material. The active region and conductive material are separated by an insulating layer. The strips form an array of capacitors which are more tightly packed than the prior art and which are less sensitive to alignment errors than the prior art.
