  • Publication number: 20200152574
    Abstract: A method for forming a silicon photonics interposer having through-silicon vias (TSVs). The method includes forming vias in a front side of a silicon substrate and defining primary structures for forming optical devices in the front side. Additionally, the method includes bonding a first handle wafer to the front side and thinning down the silicon substrate from the back side and forming bumps at the back side to couple with a conductive material in the vias. Furthermore, the method includes bonding a second handle wafer to the back side and debonding the first handle wafer from the front side to form secondary structures based on the primary structures. Moreover, the method includes forming pads at the front side to couple with the bumps at the back side before completing final structures based on the secondary structures and debonding the second handle wafer from the back side.
