Computation and analysis of thermal fields, mass transfer during the whole growth cycle, crystal shape evolution, powder charge degradation, stress and dislocation dynamics during both the growth and cooling
VR-PVT SiC has been updated. New features include automatic switching between phases in the powder source (pure carbon, graphitized SiC with simultaneous coexistence of SiC and carbon, or pure SiC), programmable variation of argon/nitrogen ratio in the gas, improved boundary shifting procedure in long-term growth.
On May 19-21, 2021, STR is participating in International Conference on “Sustainable Materials and Technologies for Bio and Energy Applications (SMTBEA-2021)”. Join the conference online and attend Andrey Smirnov’s talk “Numerical modeling in growth of oxide crystals from the melt” on Friday, May 21st at 3:30 p.m. Indian Standard Time.
Unintentional carbon incorporation during MOCVD growth of GaN can now be considered in the whole family of STR software tools for modeling of epitaxy. The model can be applied to different reactor types and wide rang of process parameters, such as temperature, pressure, TMGa flow rate (growth rate), V/III ratio, and carrier gas composition. Modeling can be used both to find process parameters suitable to achieve a required doping level and to adjust the carbon concentration uniformity over large wafers.
CGSim 21.0 has been released. New tool added in Flow Module 3D makes problem setup at least 4 times faster by facilitating the transfer of the hot zone geometry along with computational mesh and material properties from Basic CGSim to Flow Module.
After a long period of COVID-19 quarantines and lockdowns, STR was thrilled to participate in Power and Compound Semiconductor International Forum organized with SEMICON China 2021 on March 18-19. Hope to see more friends and customers at the conferences to come!
SiLENSe Version 6.3 has been released. It is a major update of the software including advanced models for material properties and a new solver with improved speed and convergence.
Chemical model for simulation of THVPE has been added in HEpiGaNs software. Simulation of two-chamber source of GaCl3 is supported.
SimuLED software had a major update, namely, new SpeCLED & RATRO modules with capabilities enabling simulation of micro-LEDs were released. Improvements include new solver in RATRO.
A new version includes new features for modeling of both epitaxy and bulk crystal growth.
