Patent 9847243 was granted and assigned to Corning on December, 2017 by the United States Patent and Trademark Office.
A process for making a device comprising a thin functional substrate comprising bonding the functional substrate to a carrier substrate, forming functional components on the functional subsrate, and debonding the functional substrate from the carrier substrate by applying ultrasonic wave to the bonding interface. The application of ultrasonic wave aids the debonding step by reducing the tensile stress the functional substrate may experience.
