Abstract:
Some novel features pertain to a capacitor structure that includes a first conductive layer, a second conductive layer and a non-conductive layer. The first conductive layer has a first overlapping portion and a second overlapping portion. The second conductive layer has a third overlapping portion, a fourth overlapping portion, and a non-overlapping portion. The third overlapping portion overlaps with the first overlapping portion of the first conductive layer. The fourth overlapping portion overlaps with the second overlapping portion of the first conductive layer. The non-overlapping portion is free of any overlap (e.g., vertical overlap) with the first conductive layer. The non-conductive layer separates the first and second conductive layers. The non-conductive layer electrically insulates the third overlapping portion and the fourth overlapping portion from the first conductive layer.
