Abstract:
A substrate processing system comprising:a substrate processing apparatus including a plurality of processing units for a process using a chemically amplified resist; andan atmosphere concentration monitoring apparatus for monitoring a concentration of a specific substance in an atmospheric gas used in the substrate processing apparatus; the atmosphere concentration monitoring apparatus comprising:a plurality of measurement ports collecting atmospheric gas;port selection means for switching among the plurality of measurement ports to select one measurement port at a time;concentration measurement means for sampling the atmospheric gas through the measurement port selected by the port selection means and measuring the concentration of the specific substance comprising an alkaline component contained in the sampled atmospheric gas; andcontrol means for controlling the port selection means and the concentration measurement means;the control means including:measurement conditions setting means capable of establishing a different set of measurement conditions for each of the measurement ports;a memory storing plural set of measurement conditions established by measurement condition setting means; andcontrol executing means for controlling the port selection means and the concentration measurement means in accordance with the plural sets of measurement conditions stored in the memory;the measurement conditions for each of the measurement ports including:a port number for identifying a measurement port to be used for measurement;a concentration reference value for the specific substance; and a measurement order indicating a selection order of the plural sets of measurement conditions.
