    摘要: A plasma processing apparatus includes a processing chamber to be depressurized in a vacuum vessel with a sidewall made of a transparent or translucent dielectric material, a stage in the processing chamber to mount a wafer thereon, a coil disposed around an outer side of the sidewall and supplied with radio-frequency power for forming plasma above the stage in the processing chamber, a lamp disposed above the coil outside the vacuum vessel which radiates light onto the wafer, and a reflector disposed the coil and reflecting light to irradiate an inside of the processing chamber.

    摘要: A vacuum processing apparatus includes a processing chamber inside a vacuum vessel, a plasma forming chamber above, a dielectric plate member having multiple through-holes for introducing particles of plasma to the processing chamber between the processing chamber and the plasma forming chamber above a sample stage upper surface in the processing chamber, heating lamp arranged around an outer periphery of the plate member to irradiate an electromagnetic wave to the wafer to heat, and a ring-shaped window member for transmitting the electromagnetic wave from the lamp. The apparatus performs, from the through-holes to the wafer, supplying particles of plasma formed in the plasma forming chamber to form a reaction product, extinguishing the plasma and heating the wafer to desorb the product, and supplying particles, formed in the plasma forming chamber, of the plasma of cleaning gas to the plasma forming chamber, the processing chamber, and the window member.
