摘要 |
A semiconductor wafer, substrate, or reticle storage or shipping device that includes a photochromic indicator of exposure to undesired electromagnetic radiation. The present invention includes the incorporation of a photochromic material into the plastic used to fabricate at least a portion of a semiconductor wafer, disk, or reticle shipping or storage containers. The container may include photochromic material in the form of a transparent window or a larger portion of the container. The photochromic material may change color or darkness in response to exposure to a selected range of wavelengths of light.
