Abstract

PURPOSE:To effectively cool a heated wafer by conducting thermal exchange of a cooling gas with a cooling liquid just before coiling wafers within a conduit for feeding the cooling gas and also using the cooling liquid after the thermal exchange for cooling a wafer supporting base. CONSTITUTION:A lower electrode 1 which also works as a supporting base is provided within a reaction chamber 11 of a dry etching apparatus. As a cooling gas, for example, He gas is supplied to a cooling gas pipe 13 of a thermal exchanger 7. To the cooling liquid pipe 14 of this thermal exchanger 7, the cooling liquid cooled to -20 to +10 deg.C is supplied from a cooling liquid supplying apparatus 12 for the purpose of thermal exchange. Thereby, the cooling gas is cooled to -20 to 0 deg.C and is then supplied to a gas supply port 4 of a lower electrode 1. Meanwhile, the cooling liquid which has cooled the cooling gas passes a cooling liquid path 8 through the cooling liquid supplying port 9 to cool the lower electrode 1 and thereafter returns to the cooling liquid supplying apparatus 11 passing the cooling liquid exhaust port 10. Thereby, cooling of wafer W by the cooling gas is supported to enhance the cooling effect.
