ABSTRACT:
A capacitor comprises a pair of electrodes with an insulator between the electrodes. The insulator has a primary dielectric with at least one void. A fill dielectric is in the void to improve yield.
A method of making a capacitor comprises forming a first electrode, forming a primary dielectric having a void over the electrode, forming a fill dielectric in the void, and forming a second electrode over the dielectrics.
