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.

When sourcing these sapphire substrates, begin by confirming the exact pattern specifications match your epitaxy process requirements. The stated dimensions (2.4µm diameter, 0.6µm spacing, 1.5µm depth) are critical for light extraction efficiency. Request a certificate of analysis for each batch, detailing the measured pattern dimensions, wafer flatness (TTV, Bow, Warp), and surface roughness.
Discuss logistics and packaging with the supplier. The standard is vacuum-packed wafers in cassettes of 25. For sensitive shipments, confirm the packaging can withstand transit conditions and ask about any additional protective measures for international air or sea freight. Clarify the lead time for your order quantity and the shipping terms (e.g., FOB from a Chinese port).
Quality verification is essential for semiconductor materials. Beyond the supplier's Class 100 clean room claim, you may want to specify incoming inspection criteria for your facility. Consider requesting samples for initial evaluation of pattern uniformity, surface defects, and crystallographic quality before committing to a large-volume order.
