Abstract

A processing apparatus of this invention has an openable window portion for transferring a target processing substrate, and an inlet port for introducing the outer atmosphere. Further, the processing apparatus includes a closed processing chamber for performing predetermined processing for the target processing substrate transferred via the window portion, an exhaust means for evacuating the interior of the processing chamber, and an opening/closing mechanism for closing the inlet port, and opening the inlet port when the pressure in the processing chamber is negative.
