Claims
- 1. A package for a semiconductor wafer or a portion thereof wherein said wafer is comprised of a plurality of separate and individual die, said package comprised of:
- a first sheet having a surface to contact a first surface of the semiconductor wafer;
- an adhesive backed ring affixed to said surface of said first sheet and positioned to surround said semiconductor wafer, said ring having a thickness sufficient to extend above and protect said semiconductor wafer and sufficient to remain rigid and approximately flat; and
- a second sheet to cover a second surface of said semiconductor wafer.
- 2. A package for a semiconductor wafer which comprises:
- a first sheet having a surface to contact a first surface of the semiconductor wafer;
- an adhesive backed ring of about one-eighth inch in thickness, said ring affixed to said surface of said first sheet and positioned to surround said semiconductor wafer and extending above said semiconductor wafer; and
- a second sheet to cover a second surface of said semiconductor wafer.
- 3. A package for storing and protecting semiconductor dice in the form of an expanded wafer which comprises:
- a first sheet of a stretchable material for contacting a first surface of said dice, said first sheet in a stretched state to separate said dice;
- an adhesive backed ring affixed to said first sheet and positioned to surround said dice, said ring having sufficient thickness to extend above said dice and to provide sufficient rigidity to remain approximately flat while maintaining said first sheet in said stretched state; and
- a second sheet to cover a second surface of said dice.
