Abstract:
A method of creating a hybridized chip combining a top active optical device chip, having a substrate including a first side and active device contacts on top active devices located on the first side, the top active optical devices also being on the first side, with an electronic chip having electronic chip contacts, when at least some of the active device contacts are not aligned with at least some of the electronic chip contacts when the top active optical device chip and the electronic chip are superimposed, each of the at least some active device contacts having an electrically corresponding electronic chip contact, the method comprising:attaching a carrier to the top active optical device; creating sidewalls defining openings in the substrate extending from the active device contacts on the first side through the substrate to a bottom side of the substrate opposite the first side at points on the bottom side substantially coincident with the active device contacts on the top side; making the sidewalls electrically conductive to form electrically conductive paths from the active device contacts to the points; and connecting the points to locations correspondingly aligned with the at least some electronic chip contacts with an electrically conductive material located on the bottom side of the active optical device chip.
