Abstract:
1. A multi-layer capacitor formed above a substrate, the multi-layer capacitor comprising: a first electrode layer having a first tapered sidewall formed at an edge of the first electrode layer; a first dielectric layer at least partially formed over the first electrode layer and the first tapered sidewall of the first electrode layer, the first dielectric layer having a second tapered sidewall formed at an edge of the first dielectric layer, wherein the second tapered sidewall is staggered in position with respect to the first tapered sidewall; a second electrode layer at least partially formed over the first dielectric layer; a second dielectric layer formed at least partially over the second electrode layer; and a third electrode layer at least partially formed over the second dielectric layer, wherein the second dielectric layer has a third tapered sidewall at an edge of the second dielectric layer, and wherein the second electrode layer comprises a contact region that extends beyond a perimeter of the second dielectric layer, and a contact hole extends down to the contact region.
