发明名称 Solder contacts and methods of forming same
摘要 An integrated circuit that comprises a substrate and a structured layer on the substrate. The structured layer comprises an opening to the substrate, a first field and a second field on the substrate, wherein the first field and the second field, at least in part, overlap with the opening. The integrated circuit further comprises a first material in the area of the first field and a second material in the area of the second field. The first material impedes a wetting by a solder material, and the second provides a wetting by the solder material.
