  • Abstract
    This paper reports improved fabrication processes on SAW-semiconductor coupled devices using epitaxial lift off (ELO) and film bonding technology. In order to realize a rugged bonding interface between the semiconductor film and LiNbO3, we studied (1) enhancement of release etching, (2) surface treatment of the film and substrate to realize a hydrophilic surface, (3) co-integration with polyimide film. We also report film transfer technology using polyimide and basic experimental results on SAW-semiconductor coupled test devices.
