发明名称 Integrated circuits having TSVs including metal gettering dielectric liners
摘要 An IC includes a substrate having a semiconductor top surface and a bottom surface, wherein the semiconductor top surface includes one or more active circuit components and a plurality of through silicon vias (TSVs) extending through the substrate. The plurality of TSVs include an outer dielectric liner. The dielectric liner includes at least one halogen or a Group 15 element metal gettering agent in an average concentration from 1 to 10 atomic %. A metal diffusion barrier layer is on the dielectric liner and a metal filler is on the metal barrier layer. The metal gettering agent getters metal filler that escapes the metal barrier layer.
