By Zone-Melting Liquids TRIZ Cases
- Laser Annealing Line Beam Timing for Uniform Polycrystalline Silicon
Synchronized split laser pulses extend melting in a uniform line beam, improving polycrystalline silicon uniformity and reducing defects.
- Laser-Heated Crystal Growth for Compositionally Stable Single Crystals
Localized laser heating at the solid-liquid interface maintains the temperature gradient needed to prevent compositional supercooling during crystal growth.
- Adaptive Melting Zone Control for Stable Single Crystal Growth
Image-based feedback and self-learning control keep the melting zone shape stable despite temperature and viscosity fluctuations.
