Sapphire wafers are widely used in LED production, optoelectronic devices, high-frequency circuits, and as substrates for semiconductor epitaxy due to their excellent thermal conductivity and optical transparency.
Sapphire wafers are typically available in diameters from 2” to 12” with thicknesses ranging from 0.2 mm to 1.0 mm or customized per client requirements.
Yes, sapphire wafers can be polished, etched, coated, or patterned for specific optical, electronic, or mechanical applications.
Quality is ensured through strict crystal growth controls, precise slicing, chemical mechanical polishing (CMP), and rigorous inspection for surface defects and crystallographic orientation.
Yes, sapphire wafers have excellent thermal and chemical stability, making them ideal for high-temperature and harsh-environment applications.
SiC wafers are used in high-power electronics, electric vehicles, renewable energy inverters, and RF devices due to their wide bandgap, high thermal conductivity, and high breakdown voltage.
Common types include 4H-SiC and 6H-SiC, each offering specific electronic properties suitable for power devices, MOSFETs, and Schottky diodes.
Yes, SiC wafers can be customized in diameter, thickness, and doping type (n-type or p-type) to meet different device requirements.
SiC wafers require complex crystal growth (physical vapor transport), precision slicing, and polishing, which increases manufacturing cost compared to conventional silicon wafers.
Surface quality is ensured through chemical mechanical polishing (CMP), defect inspection, and rigorous crystal orientation verification to meet semiconductor-grade standards.
GaN wafers are widely used in high-efficiency LEDs, power electronics, RF amplifiers, and next-generation communication devices due to their high electron mobility and wide bandgap.
GaN wafers are available as bulk GaN substrates or GaN epitaxial layers grown on sapphire, SiC, or silicon substrates.
Yes, GaN wafers can be tailored in thickness, diameter, and epitaxial layer specifications to suit LED, power, and RF device manufacturing.
Challenges include lattice mismatch with substrates, managing stress and defects, and ensuring high crystalline quality for high-performance devices.
Quality is verified using X-ray diffraction (XRD), atomic force microscopy (AFM), photoluminescence (PL), and defect density inspections to ensure optimal device performance.
