METHOD AND APPARATUS FOR TRANSPORTATION OF HIGHLY CLEAN MATERIAL.

摘要

A method and apparatus for transportation of wafers from one stage to another in a manufacturing process while protecting clean silicon surfaces and thin films on them from contamination through the air. The apparatus includes a wafer container (101) having a gas inlet (103) and a gas outlet (112), an inert gas container (103) having an inert gas sealed therein, and a piping (114) for connecting the gas inlet (113) of the wafer container to the inert gas container (103) and for sending the inert gas in the inert gas container to the wafer container (114), and wafers are transported while the inside of the wafer container is constantly purged by introducing the inert gas.
