BONDING OF LIGHT EMITTING DIODES HAVING SHAPED SUBSTRATES AND COLLETS FOR BONDING OF LIGHT EMITTING DIODES HAVING SHAPED SUBSTRATES

摘要

Bonding of flip-chip mounted light emitting devices having an irregular configuration is provided. Light emitting diodes having a shaped substrate are bonded to a submount by applying forces to the substrate an a manner such that shear forces within the substrate do not exceed a failure threshold of the substrate. Bonding a light emitting diode to a submount may be provided by applying force to a surface of a substrate of the light emitting diode that is oblique to a direction of motion of the light emitting diode to thermosonically bond the light emitting diode to the submount. Collets for use in bonding shaped substrates to a submount and systems for bonding shaped substrates to a submount are also provided.
