Analysis software for showerhead-type CVD, 'DSMC-Neutrals'

Dilute fluid analysis software 'DSMC-Neutrals' that also supports 'shower head type CVD' analysis.

Simulation Analysis of Gas Flow in Showerhead-Type CVD Equipment Initially compatible with various simulations 【Features】 ■ By adopting a non-structured mesh, it is possible to compute the exact shape of complex actual equipment. ■ High parallel efficiency allows for quick computation results even for large-scale shapes. ■ Since a particle method is used, unlike fluid models, convergence solutions can be obtained even with poor quality computational grids. ■ With comprehensive technical support, even those new to simulations or busy with experiments can reliably achieve results. ◆ Compatible with various cases ◆ - Simulation of rarefied gas flow in a vacuum chamber - Simulation of thin film generation in semiconductor manufacturing - Simulation of thin film generation in semiconductor manufacturing such as Chemical Vapor Deposition (CVD), Organic Light Emitting Diodes (OLED), and Molecular Beam Epitaxy (MBE) ◆ Outputs various computation results ◆ - Calculation of chemical reactions - Calculation of chemical reactions from Arrhenius-type reaction data - Calculation of dissociation, recombination, and molecular (atomic) exchange reactions - Multiple reaction equations can be set up on the GUI *We also offer contract analysis, so please feel free to contact us.
