Abstract:
A carrier for a reticle used in semiconductor manufacture, comprising:a bottom cover; a top cover; the bottom cover and the top cover forming a carrier for receiving the recticle; a transparent window in at least one of the bottom cover and the top cover to allow visual inspection of an overall reticle mask area, where the transparent window allows deep ultra-violet (DUV) radiation inspection of the reticle mask area of the reticle installed within the carrier, and allows a vacuum ultra-violet (VUV) radiation photochemical cleaning of the reticle mask area of the reticle installed within the carrier, and where the transparent window is DUV and VUV degradation resistant; and, at least one of the bottom cover and the top cover enabling removal of the reticle from the carrier during extreme ultra-violet (EUV) or shorter wavelength radiation mask exposure.
