1. A method comprising:
- providing an interposer comprising;
a substrate; and
a first through-substrate via (TSV) penetrating through the substrate;
forming a first oxide layer on a surface of the interposer;
bonding a glass substrate to the interposer through a fusion bonding, with the first oxide layer being between the interposer and the glass substrate; and
forming a second TSV in the glass substrate and electrically coupled to the first TSV.

Abstract
A method comprises providing an interposer comprising a substrate and a first through-substrate via (TSV) penetrating through the substrate, forming a first oxide layer on a surface of the interposer, bonding a glass substrate to the interposer through a fusion bonding, with the first oxide layer being between the interposer and the glass substrate and forming a second TSV in the glass substrate and electrically coupled to the first TSV.
