Abstract: Some embodiments of the present disclosure relate to an integrated chip including an extended via that spans a combined height of a wire and a via and that has a smaller footprint than the wire. The extended via may replace a wire and an adjoining via at locations where the sizing and the spacing of the wire are reaching lower limits. Because the extended via has a smaller footprint than the wire, replacing the wire and the adjoining via with the extended via relaxes spacing and allows the size of the pixel to be further reduced. The extended via finds application for capacitor arrays used for pixel circuits.
