Abstract
Through substrate via (TSuV) structures and method of making the same are disclosed herein. In embodiments, TSuV structures are metal filled selectively to avoid forming significant metal overburden on non-via surfaces of the substrate. In certain embodiments, post-fill metal removal/planarization operations are eliminated for reduced process complexity and manufacturing cost. In embodiments, selective metal fill entails selective electroless or electrolytic deposition. Both front side and back side selective deposition methods are described along with features of through substrate via structures made with such methods.
