Adhesive-less substrate bonding to carrier plate
Last updated:
Abstract:
Methods for bonding and de-bonding a thin substrate film to a carrier plate are provided herein. In some embodiments, a method of processing a semiconductor substrate includes applying a polymer layer that is non-adhesive to a carrier plate formed of a dielectric material. A second layer is then applied to the polymer layer. One or more redistribution layers are then formed on the second layer. The second layer is then separated from the carrier plate via at least one of magnetic induction heating, infrared exposure, or electrostatic repulsion.
