Abstract
A method for producing a conductive through-via, including applying a seed layer on a surface of a first substrate, and forming a surface modification layer on at least one of the seed layer and a second substrate. Next, the second substrate is bonded to the first substrate with the surface modification layer to form an assembly. A conductive release layer is formed in the at least one through-via by placing a conductive release material into the at least one through-via. The conductive release layer is present on the seed layer and in the at least one through-via. A conductive metal material is applied to the at least one through-via, and the second substrate is removed from the assembly after applying the conductive metal material to the at least one through via.
