[Example] Particle-PLUS Roll-to-Roll Sputtering

basic information

**Features** - The time scheme uses an implicit method, allowing for stable time evolution calculations over a large time step Δt compared to conventional methods. - The collision reaction model between neutral gas and electrons and ions employs the Monte Carlo Scattering method, enabling accurate and rapid calculations of complex reaction processes. - The neutral gas module determines the initial neutral gas distribution used in the above plasma module, allowing for quick evaluation of gas flow using the DSMC method. - The sputtered particle module calculates the behavior of atoms sputtered from the target in plasma and neutral gas environments, such as the flux distribution on opposing substrates, which can be evaluated in a short time. *For other functions and details, please feel free to contact us.*

Detailed information

• 

  It is possible to create a mesh for the cut cell. The figure on the right shows an enlarged view near the boundary of the rotating target mesh.

• 

  It shows the Ar+ ion density distribution and flux distribution. It can be confirmed that the plasma is trapped by the magnetic field.

• 

  It shows the flux distribution to the substrate with the density distribution of tantalum. Because a mesh using the cut cell method is employed, the behavior of tantalum, which is a sputtered particle, is accurately calculated. Therefore, the flux to the substrate can also qualitatively demonstrate good agreement with the experiments.
