Abstract:
1. A capacitor structure, comprising: a conductive region; a first dielectric layer over the conductive region; a conductive material within the first dielectric layer, wherein the conductive material is on and contacts the conductive region and forms a first plate electrode of the capacitor structure; an insulating layer within the first dielectric layer and contacting opposing sides of the conductive material in a cross sectional view; a first conductive layer within the first dielectric layer and surrounding the insulating layer, wherein the first conductive layer forms a second plate electrode of the capacitor structure; a second conductive layer having a lateral extension of a first length from the first conductive layer at a top surface of the first dielectric layer; a second dielectric layer over the first dielectric layer; and a third conductive layer within the second dielectric layer and on and in contact with the conductive material.
