Polycrystalline Material Growth TRIZ Cases
- Vitreous Silica Crucible Reference Point for Silicon Crystal Yield
A vitreous silica crucible with a fixed reference point detects defect locations to prevent bubble exposure and improve single crystal silicon ingot yield.
- Epitaxial Substrate Lattice Misfit Relief
Amorphous interface layer absorbs lattice misfit between silicon base and group-III nitride layers, reducing dislocation density.
- Quasi-single-crystal metal film via mechanical stretching
Mechanical stretching aligns crystal grains in a metal film to achieve three-axis preferred orientations, resolving slow conventional production speeds.
- III-V Compound Crystal Substrate Separation via Laser Peeling
Laser irradiation creates a peeling layer in the buffer zone, allowing III-V compound crystals to separate from substrates without external force.
- Ultra-hard Carbon Film via Graphene Compression
High-pressure treatment converts sp2 graphene to sp3 diamond-like structure, achieving 100 GPa hardness while maintaining structural stability.
- Slidable Carbon Electrode for Polysilicon Rod Thermal Stress
A slidable carbon electrode accommodates all-directional expansion of a growing polysilicon rod.
- Multi-heater diamond growth temperature gradient control
Independent heater zones maintain stable thermal gradients to prevent inclusion defects and boost diamond growth rates.
- Beta-Ga2O3 Substrate Orientation for Epitaxial Quality
Using a beta-Ga2O3 substrate with a (010) plane improves crystalline quality and interface steepness for Schottky-barrier diodes.
- Hexagonal Grain Selector Filter for Single Crystal Casting
Hexagonal pore filters block stray grains while allowing primary dendrites to pass, resolving alignment and cracking issues in turbine blade production.
- Laser-Assisted Crystal Growth for Large-Diameter Rods
Xenon lamps and lasers heat feed rods to resolve uneven melting in large-diameter crystals.
- Semi-insulating Compound Semiconductor Substrate Uniformity
A semi-insulating compound semiconductor substrate with controlled specific resistance distribution across crystal orientations.
- Bismuth-Substituted RIG Film for Low-Loss Optical Isolators
A bismuth-substituted rare-earth iron garnet film reduces insertion loss below 0.6 dB through precise composition control.
- Local Carbon-Supply Device for Wafer-Level Graphene Single Crystal Growth
A local carbon-supply device directs carbon flow through a substrate hole to nucleate graphene single crystals on nickel-copper alloy.
