Abstract
A vacuum process apparatus includes a plurality of cassettes for holding samples, a transporter which transports the samples, a plurality of vacuum process chambers each for processing samples one by one, an evacuator which evacuates the vacuum process chambers, and a load chamber and an unload chamber communicating with the vacuum process chambers. An apparatus controller is provided for controlling transporting and processing of the samples. The apparatus controller measures a time period for transporting each of the samples and a processing time period for processing a sample in each of the vacuum process chambers, and determines a next order of extraction of the samples from the plurality of cassettes based on the measured time periods.
