Abstract:
1. A method for bonding a group III-nitride based device formed on a silicon substrate, the method comprising: providing a silicon substrate having at least one group III-nitride based device thereon, the group III-nitride based device comprising at least one group III-nitride layer near the silicon substrate, and remote from the silicon substrate a dielectric layer comprising at least one via configured to electrically contact the at least one group III-nitride layer; forming a stiffener layer over the at least one group III-nitride based device leaving the at least one via exposed; flipping over and bonding the at least one group III-nitride based device to a submount, wherein the stiffener layer physically contacts the submount and the submount is electrically connected to the at least one group III-nitride layer through the via; and removing the silicon substrate to expose the at least one group III-nitride based device.
