Wafer cassette in wafer carrier
First Claim
1. A wafer carrier comprising:
- a cassette havingan upper opening,a lower opening,a first side wall having, on an inner surface thereof, a first plurality of parallel alignment grooves,a second side wall, opposite to said first side wall, having, on an inner surface thereof, a second plurality of parallel alignment grooves;
an upper presser plate, covering said upper opening of said cassette, and havinga first upper engageable part attached to an upper portion of said first side wall of said cassette,a second upper engageable part, opposite to said first upper engageable part, and attached to an upper portion of said second side wall of said cassette, anda plurality of upper parallel elastic plates extending between said first upper engageable part and said second upper engageable part and each of said upper parallel elastic plates including a protrusion having a groove which forms a plate center line; and
a lower presser plate, covering said lower opening of said cassette, and havinga first lower engageable part attached to a lower portion of said first side wall of said cassette,a second lower engageable part, opposite to said first lower engageable part, and attached to a lower portion of said second side wall of said cassette, anda plurality of lower parallel elastic plates extending between said first lower engageable part and said second lower engageable part and each of said lower parallel elastic plates including a protrusion having a groove which forms a plate center line.

Abstract
A wafer cassette of a wafer carrier holds a plurality of wafer materials such as semiconductor single crystal silicon wafers. The wafer cassette is contained in a box body having a covering for transportation and storage of the silicon wafers with safety from contamination and mechanical damage. The wafer cassette is a casing have an opening in the upper and lower surfaces and having a pair of opposite side walls each of which is provided on the inner surface thereof with a plurality of alignment grooves for receiving wafer materials in parallel with each other. The wafer cassette is provided with wafer presser plates each covering the upper or lower surface in a freely demountable fashion each of which having a pair of engageable parts on two opposite sides thereof. A plurality of elastic plates are provided at the center of the plates, between the pair of the engageable parts, in alignment in the direction of the wafer materials held on the cassette. A protrusion extends from each of the elastic plates and the surface of the protrusions are engraved to form a groove having a V-shaped cross section to receive a wafer material.
