Zusammenfassung:The present disclosure relates to semiconductor structures and, more particularly, to metal interconnect structures for super (skip) via integration and methods of manufacture. The structure includes: a first wiring layer with one or more wiring structures; a second wiring layer including an interconnect and wiring structure; and at least one upper wiring layer with one or more via interconnect and wiring structures located above the second wiring layer. The one or more via interconnect and wiring structures partially including a first metal material and remaining portions with a conductive material over the first metal material. A skip via passes through the second wiring layer and extends to the one or more wiring structures of the first wiring layer. The skip via partially includes the metal material and remaining portions of the skip via includes the conductive material over the first metal material.
