Abstract
A TSV structure includes a substrate comprising at least a TSV opening formed therein, a conductive layer disposed in the TSV opening, and a bi-layered liner disposed in between the substrate and the conductive layer. More important, the bi-layered liner includes a first liner and a second liner, and a Young's modulus of the first liner is different from a Young's modulus of the second liner.
