Abstract
Provided is a vacuum processing apparatus which is capable of performing baking processing of a deposition preventive plate without impairing the function of being capable of cooling the deposition preventive plate disposed inside a vacuum chamber. The vacuum processing apparatus has a vacuum chamber for performing a predetermined vacuum processing on a to-be-processed substrate that is set in position inside the vacuum chamber. A deposition preventive plate is disposed inside the vacuum chamber. Further disposed are: a metallic-made block body vertically disposed on an inner surface of the lower wall of the vacuum chamber so as to lie opposite to a part of the deposition preventive plate with a clearance thereto; a cooling means for cooling the block body; and a heating means disposed between the part of the deposition preventive plate and the block body to heat the deposition preventive plate by heat radiation.
