Sapphire Wafer Monocrystal Al2O3 DSP SSP 2inch 4inch 6inch 8inch 12inch A plane C plane
Sapphire substrates are widely used in the production of III-V nitrides, superconductors, and magnetic epitaxial films due to their low lattice mismatch and excellent physical and chemical stability. They are extensively employed in non-polar and semi-polar epitaxial growth of materials such as GaN, ZnO, AlN, various semiconductor thin film epitaxial growth processes, Silicon On Sapphire technology, optical windows, and more.
We use only optical-grade single crystal materials, and all raw materials are sourced from 99.999% high-purity single crystal Al2O3. Our sapphire substrates have superior surface roughness, flatness, and cleanliness, making them suitable for semiconductor thin film epitaxial growth, optical windows, and other high-tech applications.
