Abstract
There is disclosed an inductive coupling plasma processing apparatus having a processing chamber for subjecting a substrate G to a plasma processing, a dielectric wall portion constituting an upper part wall portion or a side wall portion of the chamber, a high-frequency antenna, disposed on a corresponding portion of the dielectric wall portion outside the chamber, for forming an induction field in the chamber, a cover member formed of a dielectric material disposed inside the dielectric wall portion to cover the dielectric wall portion, a heater for heating the cover member, and an insulating member for insulating between the dielectric wall portion and the heater, wherein a reaction product generated by a plasma is heated at a temperature without adhering to the cover member, and heat generated by the heater is prevented from being conducted to the dielectric wall portion.
