TECHNICAL FIELD OF THE INVENTION
The present invention relates to a wafer protection container, and in particular, to protect an IC wafer from contamination and damage when the content is an integrated circuit (IC) wafer, which can be safely stored and easily loaded and unloaded. The present invention relates to an IC wafer protection container.
[0002]
[Prior art]
Conventionally, IC wafers have been stored in a cylindrical box composed of a lid and a body. Since the IC wafer is thin and fragile, a sponge layer is usually inserted between the IC wafers to prevent the IC wafer from violently shaking inside the storage box. In general, loading and unloading IC wafers is very difficult because the openings in the storage boxes that hold the IC wafers are designed to fit the size of the IC wafers. When the storage box is filled with the desired amount of IC wafer, the lid is pushed into the body and the box is closed. Since the storage box is just closed with the lid, there is a risk that the lid and body seal may be broken due to severe shaking during transportation. As a result, the IC wafer in the storage box is contaminated by the surrounding environment. This problem has conventionally been solved by covering the joint between the lid and the body member with a multilayer masking tape and sealing the storage box.
[0003]
[Problems to be solved by the invention]
However, this solution increases the cost of packaging the IC wafer product and makes the whole process more complicated.
Furthermore, it is known from the prior art that removing the IC wafer from the box requires that the box be turned over, but removing the IC wafer in this manner can damage the IC wafer and thus increase the amount of IC It leads to waste of wafer.
