ABSTRACT:
The manufacture of multi-level optical imagers and the resulting imagers are described. Multiple levels of metallization are prepared, each level having a via. The vias are aligned and a material having a higher refractive index than its surrounds is positioned within the vias to form an optical channel. The higher refractive index material may be an optical plug. A lens is mounted at one end of the optical channel and a photoconversion device is mounted at the other end.
