Abstract
A self-contained metrology wafer carrier systems and methods of measuring one or more characteristics of semiconductor wafers are provided. A wafer carrier system includes, for instance, a housing configured for transport within the automated material handling system, the housing having a support configured to support a semiconductor wafer in the housing, and a metrology system disposed within the housing, the metrology system operable to measure at least one characteristic of the wafer, the metrology system comprising a sensing unit and a computing unit operably connected to the sensing unit. Also provided are methods of measuring one or more characteristics of a semiconductor wafer within the wafer carrier systems of the present disclosure.
