[Example] Particle-PLUS Opposing Target Sputtering
Introduction of analysis examples using "Particle-PLUS": "Opposing Target Sputtering"
"Particle-PLUS" is a simulation software suitable for the research, development, and manufacturing of devices and materials using plasma. - It specializes in low-pressure plasma analysis. - By combining axisymmetric models with mirror-symmetric boundary conditions, it can quickly obtain results without the need for full device simulations. - It excels in plasma simulations for low-pressure gases, where calculations with fluid models are challenging. - It supports both 2D and 3D, allowing for efficient analysis of complex models. - As a strength of our in-house developed software, customization to fit the customer's device is also possible. ◆ Supports various applications ◆ - Magnetron sputtering - PVD, plasma CVD - Capacitively coupled plasma (CCP) - Dielectric barrier discharge (DBD) - Electrophoresis, etc. ◆ Outputs various calculation results ◆ - Potential distribution - Density distribution/temperature distribution/generation distribution of electrons and ions - Particle flux and energy flux to the wall - Energy spectrum of electrons and ions at the wall - Density distribution/temperature distribution/velocity distribution of neutral gas, etc. *For more details, please feel free to contact us.
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 devices such as magnetron sputtering systems, enabling rapid evaluation of flux distribution on opposing substrates. *For other functions and details, please feel free to contact us.*
