Abstract:
A method of filling an opening extending through a dielectric layer to an underlying conductive layer supported by a substrate, said method comprising the acts of:forming said opening in said dielectric layer such that said opening extends from an upper surface of said dielectric layer to said underlying conductive layer; forming a malleable conductive layer over said upper surface of said dielectric layer and within said opening wherein a thickness of said malleable conductive layer is substantially less than a thickness of said dielectric layer such that said malleable conductive layer lines said opening and an uppermost surface of said malleable conductive layer defines an unfilled void extending upwardly from said uppermost surface of said malleable conductive layer within said opening; and moving a portion of said malleable conductive layer formed over said upper surface of said dielectric layer into said unfilled void so as to plug said opening.
