Abstract
A method of integrated circuit fabrication is provided, and more particularly fabrication of a semiconductor apparatus with a metallic alloy. An exemplary structure for a semiconductor apparatus comprises a first silicon substrate having a first contact comprising a silicide layer between the substrate and a first metal layer; a second silicon substrate having a second contact comprising a second metal layer; and a metallic alloy between the first metal layer of the first contact and the second metal layer of the second contact.
