Abstract
A method of bonding a device wafer to a carrier wafer includes disposing a first adhesive over a central portion of a carrier wafer, the first adhesive having a first glass transition temperature, disposing a second adhesive over a peripheral portion of the carrier wafer, the second adhesive having a second glass transition temperature greater than the first glass transition temperature, and bonding the first adhesive to an active front side of the device wafer and the second adhesive to a peripheral portion of the front side of the device wafer. Related assemblies may be used in such methods.
