US Patent 9706092 Imager module with castellated interposer chip

An imager module having an interposer chip with castellated contacts electrically connected to and routing signals between an image sensor, a printed circuit board (PCB), and a voice coil motor (VCM) is disclosed. The VCM may be electrically coupled to the interposer chip via the castellated contacts. The castellated contacts may be formed by fabricating annular through silicon vias (TSVs) and then sawing through those annular TSVs. In some example embodiments, one or more surface mount devices (SMDs) may further be attached to the interposer chip with castellated contacts. The interposer chip may further have a cavity therein within which the image sensor may be attached.
