Patent ID: 7231332

Claim:
An apparatus for simulating phenomena of a particle formed of adsorbate particles and substrate particles, comprising: a kinetic condition setting unit which sets information for defining a plurality of generation periods and a corresponding number of adsorbate particles to be generated during each generation period wherein the information can include a position of a corresponding emission source, a temperature, a chemical composition of the particle, a region, a physical condition, a velocity of each atom forming the particle, and a direction; and a particle motion computing unit which generates the adsorbate particles in accordance with the information set by the kinetic condition setting unit and computes motion of the generated adsorbate particles, to simulate phenomena of said particle formed of adsorbate particles and substrate particles, each adsorbate particle having a corresponding emission source wherein for each adsorbate particle, the kinetic condition setting unit sets a region indicating a position of the corresponding emission source, and the particle motion computing unit generates each adsorbate particle in accordance with the position of the corresponding emission source.
