摘要： A shower plate of a processing gas supply unit disposed in a processing chamber of a substrate processing apparatus to supply a processing gas into a processing space in the processing chamber. The shower plate is interposed between a processing gas introduction space formed in the processing gas supply unit for introduction of the processing gas and the processing space. The shower plate includes processing gas supply passageways which allow the processing gas introduction space to communicate with the processing space. The processing gas supply passageways include gas holes formed toward the processing gas introduction space and gas grooves formed toward the processing space, the gas holes and gas grooves communicating with each other. A total flow path cross sectional area of all the gas grooves is larger than a total flow path cross sectional area of all the gas holes.

摘要： A method of plasma particle simulation capable of preventing solution divergence. A space within a housing chamber of a plasma processing apparatus is divided into a plurality of cells. A weighting factor corresponding to the number of plasma particles represented by a superparticle is set in each of the divided cells. Superparticles are set in each of the divided cells using plasma particles contained in the divided cell and the set weighting factor. The behavior of the superparticles in each of the divided cells is calculated. The weighting factor becomes smaller as the divided cell is located closer to a solid wall surface of the housing chamber.

摘要： A compensation ring 31 disposed to surround a periphery of a wafer W on a susceptor 30 is concentrically divided into an inside first compensation ring member 32 and an outside second compensation ring member 33. A width of a first compensation ring member 32 is made such thin as one to three times mean free path of treatment gas molecules, thereby suppressing heat transfer between a susceptor 30 and a second compensation ring member 33. A base of a second compensation ring member, through a layer of conductive silicone rubber 34, is made to come into an intimate contact with an upper surface of a susceptor 30, thus helping to cool.
