Patent ID: 7847247

Claim:
A method of plasma particle simulation for analyzing the behavior of a plasma particle in plasma generated in a cylindrical-shaped housing chamber included by a plasma processing apparatus by calculating the behavior of a superparticle which is a virtual particle representing a plurality of plasma particles, comprising: dividing a space within said cylindrical-shaped housing chamber into a plurality of cells; setting a weighting factor corresponding to the number of said plasma particles represented by said superparticle in each of said divided cells; setting superparticles in each of said divided cells using plasma particles contained in said divided cell and said set weighting factor; and calculating the behavior of said superparticles in each of said divided cells; wherein a volume of each of said divided cells is set small in the vicinity of a peripheral portion of said cylindrical-shaped housing chamber, and said weighting factor is set small in said divided cell in the vicinity of the peripheral portion of said cylindrical-shaped housing chamber.
