Relation between directly detected patent foramen ovale and ischemic brain lesions in sport divers

A treatment method of semiconductor wafers and the like, for carrying out step by step in a sealed container, a series of processes comprising chemical process with a cleaning chemical (chemical process) and final water rinsing process by using rinsing pure water (rinse process) and a drying process of removing attached water from the surface of an object through mixing substitution using an organic solvent, and a treatment system for the same, wherein warm pure water is fed into the sealed container after the final water rinsing process of the cleaning process is completed. The vapor or fog of the organic solvent is fed into the space procured on the upper side of the container upward the water surface of pure warm water, where the object as placed vertically in parallel arrangement is immersed and sunk. After the upper space is filled with the organic solvent, inert gas is fed into the container, while the warm pure water is discharged under aspiration from the bottom side of the container at a state such that the feeding of the organic solvent is stopped.
