从China供应商批发进口2 Inch Patterned Sapphire Substrates — FOB条款

These 2-inch patterned sapphire substrates from Jiaozuo City Crystal Photoelectric Material Co., Ltd. are monocrystalline wafers made from high-purity aluminium oxide (Al2O3) with a purity of 99.996%. They have a standard diameter of 50.8mm with a tolerance of ±0.1mm and a thickness of 430µm ±25µm. The crystal is oriented on the C-plane, and the wafer includes a primary flat of 16.0mm ±1.0mm in length.

The patterned surface is defined by features with a diameter of 2.4µm ±0.2µm, a spacing of 0.6µm ±0.2µm, and a depth of 1.5µm ±0.2µm. The wafer quality is specified with no block marks, twins, colour variations, micro-bubbles, or dispersal centres. Key flatness metrics include a Total Thickness Variation (TTV), Bow, and Warp all within 10µm. The front surface has a roughness of Ra < 0.2nm as measured by AFM, while the back surface is fine-ground with Ra between 0.5 and 1.2µm.

These substrates are used in the production of light-emitting diodes (LEDs), particularly for gallium nitride (GaN) epitaxy, where the patterned surface enhances light extraction efficiency. They are sourced by LED chip manufacturers and semiconductor research facilities. The wafers are cleaned in a Class 100 clean room and packaged under vacuum, with 25 pieces per cassette or available as single units.

Jiaozuo City Crystal Photoelectric Material Co., Ltd. is based in Jiaozuo, Henan, China, at the North of Dong Yuan Road, Shan Yang. The company operates in the photoelectric materials sector, producing crystal substrates. Its supplier profile is classified under the 'harbor' trust tier.

The listing provides technical specifications for its sapphire substrates but does not include details on the company's founding year, employee count, or revenue. The current response rate is listed as 0.00%. The product description focuses on material purity, crystallographic quality, and precise dimensional tolerances.
