Mask transport system configured to transport a mask into and out of a lithographic apparatus
First Claim
1. A mask transport system configured to transport a mask into and out of a lithographic apparatus, the mask transport system comprising:
- a first container configured to shield a top side and a bottom side of the mask, the first container comprising a top portion configured to be connected to the top side of the mask, and a bottom portion configured to be connected to the bottom side of the mask, at least a portion of the first container being at least partially translucent for radiation having a predetermined wavelength used to detect contamination on the top side or the bottom side of the mask when the mask is shielded by the first container; and
a second container configured to completely enclose the first container, the second container comprising a first part defining a first opening and an openable cover that covers said first opening, the cover being configured to open and release the first container within the lithographic apparatus or at an interface with the lithographic apparatus.

Abstract
A mask transport system is configured to transport a mask into and out of a lithographic apparatus. The mask transport system includes a first container configured to shield a top side and a bottom side of the mask. At least a portion of the container is at least partially translucent for radiation having a predetermined wavelength used to detect contamination on the top side or the bottom side of the mask when the mask is shielded by the first container. The mask transport system also includes a second container configured to enclose the first container. The second container includes a first part defining a first opening and an openable cover that covers the first opening. The cover is configured to open and release the first container within the lithographic apparatus or at an interface with the lithographic apparatus.
