Abstract
The present invention is a conveying unit having a controller for detecting information corresponding to the thickness of each of a plurality of raw substrates, assigning desired identifiers to the raw substrates, storing the identifiers, and causing a conveyor to convey each of the raw substrates or controlling processing conditions for a plurality of processing chambers with the identifiers corresponding to the thickness of each of the raw substrates. Thus, even if one cassette accommodates a plurality of raw substrates, the conveyor can smoothly load the same type of raw substrates to the accommodating cassette and unload them therefrom in a simple structure. The controller sets desired processing conditions for each of the processing portions corresponding to the identifiers.
