Abstract
A system and a method for protecting semiconductor wafers is disclosed. A preferred embodiment comprises a carrier with a central region and an exterior region. The exterior region preferably has a thickness that is greater than the central region, to form a cavity in the carrier. An adhesive is preferably placed into the cavity, and a semiconductor wafer is placed onto the adhesive. The edges of the semiconductor wafer are protected by the raised exterior region as well as the displaced adhesive that at least partially fills the area between the semiconductor wafer and the exterior region of the carrier.
