Abstract

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. A process condition measuring device surveys conditions in a target environment and records them in a memory for later transmission or downloading.
