Abstract
A method of forming a package assembly includes forming a first dielectric layer over a carrier substrate; forming a conductive through-via over the first dielectric layer; treating the conductive through-via with a first chemical, thereby roughening surfaces of the conductive through-via; and molding a device die and the conductive through-via in a molding material.
