US Patent 7135852 Integrated process condition sensing wafer and data analysis system

A process condition measuring device and a handling system may be highly integrated with a production environment where the dimensions of the process condition measuring device are close to those of a production substrate and the handling system is similar to a substrate carrier used for production substrates. Process conditions may be measured with little disturbance to the production environment. Data may be transferred from a process condition-measuring device to a user with little or no human intervention.
