In an embodiment, a substrate includes semiconductor material and a conductive via. The conductive via includes a via in the substrate, a conductive plug filling a first portion of the via, and a conductive liner layer that lines side walls of a second portion of the via and is electrically coupled to the conductive plug. The conductive liner layer and the conductive plug have different microstructures.

Substrate and method

A method of forming an electronic device includes forming a first opening and a second opening in a workpiece. The first opening is deeper than the second opening. The method further includes forming a fill material within the first opening to form part of a through via and forming the fill material within the second opening.
