  • System for detecting warped carriers and associated methods
    Patent number: 7326025
    Abstract: Disclosed herein is a warp detection system (200) for determining warping in a carrier (110) configured to carry substrates (120) for processing. In one embodiment, the system (200) includes a guide plate (210) configured to guide a path of the carrier (110) during the processing, where the guide plate (210) is positioned underneath the carrier (110). In addition, the system (220) includes a plurality of sensors (230) positioned within the guide plate (210), wherein each of the plurality of sensors (230) is configured to measure a distance of a respective area of the carrier (110) from the guide plate (210). Also in this embodiment, the system (200) includes a processing device (310) configured to receive the measured distances and determine warping in the carrier (110) based on differences between the measured distances.
