摘要: In an etching method of etching a tungsten film, the method is provided to execute a generating a surface reaction layer on a tungsten film that is formed on a surface of a base material by supplying a reactive species including fluorine which is generated in plasma onto the base material for a first predetermined time in a state where the base material of which the tungsten film is formed on at least a portion of the surface is cooled to a melting point temperature or lower of a tungsten fluoride, and a removing the surface reaction layer that is generated on the tungsten film by heating the base material of which the surface reaction layer is generated on the tungsten film to a boiling point temperature or higher of the tungsten fluoride for a second predetermined time.

摘要: A method for etching a titanium nitride film includes a first process of supplying reactive species, which include hydrogen and fluorine, to a base material including a titanium nitride film on at least a part of a surface, and a second process of vacuum-heating the base material to remove the surface reaction layer that is generated on the surface of the titanium nitride film in the first process.

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.
