Abstract: A processing apparatus performs a predetermined process on an object to be processed by supplying halogen-based gas into a chamber in which a vacuum is maintained, to which chamber a member having an oxide film formed on a surface thereof is connected, or which chamber has an oxide film formed on a surface thereof, wherein the predetermined processing is performed on the target object once or a plurality of times in the chamber. Later, oxygen gas or dry air is supplied to the chamber to purge the chamber, and then the chamber is opened and exposed to the atmosphere.

Abstract: There is provided a method for forming an organic monomolecular film on a surface of a workpiece with a network structure of Si and O formed in at least a portion of the surface. The method includes: performing a surface treatment on the workpiece such that the surface has a state where bonding sites of an organic monomolecular film material to be used exist at high density; and supplying the organic monomolecular film material to the workpiece subjected to the surface treatment and forming the organic monomolecular film on the surface of the workpiece.
