Abstract
The present invention provides a system for supplying a high-pressure medium gas suitable for processing a semiconductor to be processed by heating under isostatic pressure in a short cycle. The system includes a gas holder containing a high-pressure medium gas, a compressor for pressurizing the high-pressure medium gas supplied from the gas holder, a high-pressure vessel having a heater, an accumulator for storing the high-pressure medium gas pressurized by the compressor, a first evacuation unit for evacuating the inside of a pipeline for the high-pressure medium gas, a vacuum casing for holding the opening of the high-pressure vessel in a vacuum, a second evacuation unit for evacuating the inside of the vacuum casing, and a valve unit for connecting the high-pressure vessel and the accumulator so that series connection and parallel connection can be switched on the outlet side of the compressor.
