Patent attributes
There is set forth herein an optoelectrical device, comprising: a substrate; an interposer dielectric stack formed on the substrate, the interposer dielectric stack including a base interposer dielectric stack, a photonics device dielectric stack, and a bond layer that integrally bonds the photonics device dielectric stack to the base interposer dielectric stack. There is set forth herein a method comprising building an interposer base structure on a first wafer having a first substrate, including fabricating a plurality of through vias in the first substrate and fabricating within an interposer base dielectric stack formed on the first substrate one or more metallization layers; and building a photonics structure on a second wafer having a second substrate, including fabricating one or more photonics devices within a photonics device dielectric stack formed on the second substrate.
