Abstract
A package and a method of packaging semiconductor devices, especially in expanded wafer form. The package is formed by sticking an adhesive backed ring to the plastic sheet upon which the expanded wafer is affixed so that the ring surrounds the wafer. The adhesive backed ring holds the plastic sheet securely and protects the surface of the wafer. The package is completed by covering the wafer with a second protective sheet and vacuum sealing in a plastic bag.
