The top section cross section can have a minimum cross section corresponding to design rules, and the top section depth can correspond to a workable aspect ratio. The top section via can be filled or plugged so that top side processing can be continued. The bottom section via can have a larger cross section for ease of forming a conductive path therethrough. The bottom section via extends from the back side to the bottom of the top section via and is formed after the substrate has been thinned. The TSV is can be completed by forming a conductive path after removing sacrificial fill materials from the joined top and bottom section vias.
