Abstract

Various embodiments of the present disclosure are directed towards a method for forming an integrated chip, the method includes forming a through substrate via (TSV) in a first substrate. The TSV continuously extends from a first surface of the first substrate to a second surface of the first substrate. A conductive contact is formed on the second surface of the first substrate. The conductive contact comprises a first conductive layer disposed on the TSV. An upper conductive layer is formed between the conductive contact and the TSV. The upper conductive layer comprises a silicide of a conductive material of the first conductive layer.
