Patent ID: 7728372

Claim:
A capacitor, comprising: a first conductive layer; an insulator having a first length and a first top surface and a second top surface, said first and second top surfaces being directly on top of said first conductive layer, wherein said first top surface is higher than said second top surface; a second conductive layer having a second length on said insulator, said second conductive layer on said insulator at an interface with said insulator, said second length of said second conductive layer being shorter than said first length of said insulator at said interface; an etch stop on said second conductive layer and a second protective on said etch stop, said second protective layer and said etch stop having substantially equal length; and, a first protective layer adjacent said interface and directly above said second top surface of said insulator, top surface of said first protective layer co-planar with said first top surface of said insulator and at least one side edge of said first protective layer abutting the side edge of said insulator.
