Laser Diode Submounts (Heat Spreaders): Ultra precise patterning (+/-3 micron tolerance) of thin film metals on high thermal conductivity dielectrics are used for diode submount (heat spreader) applications.

Edge emitting laser diodes operating at high current densities require a heat spreader placed between the device active region and metal carrier package. Metal pads, for diode mounting, on the top surface edge of the submount, facilitate the diode edge mount requirements at edge gap geometrics down to 5 microns.

Au/Sn selective deposition on the Ti/Pt/Au edge pads precludes the need for small solder preform handling and potential solder rollup in critical submount edge areas.
