Elevate Your Technology with Our Sapphire Wafers The Perfect Combination of Durability and Performance
Elevate your technology with our premium Sapphire Wafers, engineered for excellence in LED, RF, and power electronics applications. Renowned for their exceptional thermal conductivity, optical transparency (95%+ transmittance from UV to IR), and chemical inertness, these wafers provide an unbeatable platform for device reliability and efficiency.
Crafted from ultra-pure, single-crystal sapphire (Al₂O₃), our wafers feature ultra-smooth surfaces (Ra < 0.3 nm) and precise thickness tolerances, minimizing defects and enhancing yield in epitaxial growth processes. Ideal for GaN-based LEDs, MEMS sensors, and high-frequency RF devices, they withstand extreme temperatures and corrosive environments, ensuring long-term performance.
Available in customizable diameters (2"–6"), orientations (C-plane, R-plane, M-plane), and polished grades, our Sapphire Wafers adapt seamlessly to your R&D and production needs. Backed by rigorous quality control and ISO-certified manufacturing, they deliver consistency and cost-efficiency at scale.
Step into a brighter future with Sapphire Wafers. Contact us today to unlock unmatched durability, clarity, and innovation for your next-generation devices.
