摘要:
A coolant flow path for cooling a dielectric window of a side wall of a processing container of the plasma processing apparatus is provided. A coolant flows in a liquid or gaseous state in the coolant flow path without phase transition. At least a portion of the coolant flow path extending in a circumferential direction of the side wall has a cross-sectional area decreased toward downstream from upstream.
