Polycrystalline Material Growth TRIZ Cases
- Monocrystalline Silicon Wafer Gettering via Localized BMD Defects
Thermal treatments create localized BMD maxima at controlled depths, maintaining getter efficiency above 90% despite long-term storage.
- Electron Beam Polysilicon Refining for High Purity Production
Vacuum electron beam melting refines raw silicon into high purity ingots, resolving the trade-off between production efficiency and semiconductor-grade purity.
- Gallium Oxide Crystal Growth Suppressing Iridium Loss
Injecting carbon dioxide suppresses iridium oxidation and alloy formation, reducing material loss below 0.25% while sustaining high-temperature processing.
- Single-Source Precursor for Doped Semiconductor Nanocrystals
A single-source solid precursor matrix synthesizes doped semiconductor nanocrystals, eliminating toxic surfactants and enabling multicolor emission.
- Tunable Microwave Plasma Reactor for High-Pressure Diamond Synthesis
Adjusting cavity length and iris diameter resolves the trade-off between high deposition rates and crystalline quality in diamond synthesis.
- SiC Single Crystal Growth with Oriented Basal Plane Dislocations
A SiC single crystal uses specific seed offset angles to align basal plane dislocations along stable directions.
