Abstract

An object of the present invention is to grasp easily a process history of a target object such as a semiconductor wafer. The processing apparatus of the present invention includes: a processing apparatus body which includes a plurality of process units for executing a prescribed process to a target object, and transport mechanism for transporting said target object between the process units; a first controller for controlling the processing apparatus as a whole; a second controller for controlling the process units; an information storage section for taking in a signal transmitted and received between the first and second controllers; and a host computer for monitoring operation states of the process units. The present invention is extended to a processing system including a plurality of the processing apparatuses connected with a host computer which is further connected with a monitor computer through a communication network.
