Abstract

A capacitor structure having a capacitor with a top electrode, a bottom electrode, and a capacitor dielectric layer between the top and bottom electrodes is disclosed. The capacitor includes upper and lower portions. The demarcation between the upper and lower portion is located between top and bottom surfaces of the capacitor dielectric layer. A dielectric layer is provided on the sidewalls of the upper portion of the capacitor to prevent shorting between the electrodes that can be caused by a conductive fence formed during processing.
