Partile In Cell with Monte Carlo Collision Module

PIC-MCCM

PIC-MCCM computes spatial distribution of density, energy of charged particles and electric field etc., in a reactor by particle model.

Description

PIC-MCCM is a module to compute plasma parameters of non-equilibrium and low temperature plasma in various semiconductor manufacturing reactors, magnetron sputtering reactors and thin-film manufacturing reactors. A numerical method of behavior of charged particles is PIC(Particle-In-Cell) method and a numerical method of collision between charged particles and neutral particles (elastic, inelastic such as ionization, excitation, charge exchange and dissociation etc.) is Monte Carlo method, respectively. PIC-MCCM is a module to compute the motion of charged particles by small time steps(<=ns) in the electric field generated by spatial charge and electrodes(RF,DC and grounded),insulators and/or ICP coils under magneto-statistical field in two-dimensional Cartesian or cylindrical (axial symmetry model) coordinates.

Input data

  • Specify computational domain, RF and DC electrodes, insulators and/or ICP coils defined by two-dimensional rectangular mesh system in Cartesian or cylindrical (axial symmetry model) coordinates.
  • Specify species of fed or background gas
  • Select the reaction (elastic, ionization, excitation, dissociation and recombination etc.)between particles defined by internal database through PEGASUS/GUIM
  • Specify file name containing magnetic flux density

Output data

  • Spatial distributions of density, energy and flow velocity for each charged particles.
  • Spatial distributions of source rates of charged particles, radical and excited neutral particles.
  • Particle and energy fluxes of each charged particles on the targets and walls.
  • Spatial distributions of electric potential and electric field.
  • Energy distribution function of charged particles.
