Description:
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.
Character
1. High optical transparency
Sapphire wafer with its high optical transparency, finds widespread
applications as a dielectric material in microelectronic tubes,
ultrasonic transducers, waveguide laser cavities, and other optical
components. It serves as a window material for infrared military
devices,spacecraft, high-power lasers, and optical communication
systems.
2. High hardness, strength, high operating temperature, wear
resistance, and corrosion resistance
Sapphire wafer is valued for its high hardness, strength, high
operating temperature, wear resistance, and corrosion resistance,
making it suitable for harsh environments. It is commonly used in
applications such as boiler water gauges (high-temperature
resistance), barcode scanners, precision bearings (wear
resistance), coal and natural gas industries, oil well sensing
sensors, and detector windows (corrosion resistance).
3. Electrical insulation, transparency, good thermal conductivity
Sapphire wafer, known for its electrical insulation, transparency,
good thermal conductivity, and high hardness, can serve as a
substrate material for LEDs, microelectronic circuits,
ultra-high-speed integrated circuits, and other integrated
circuits.

Applications:
1. Microelectronic IC applications, especially ultra-high-speed
integrated circuits (SOS), typically involve heteroepitaxial
silicon grown on R-plane (1-102) sapphire wafers.
2. Hybrid microelectronics: Hybrid microelectronic products mainly
include HIC and MCM, which have high wafer requirements.
3. Sapphire wafers, known for stable dielectric constants and low
dielectric losses, are the most commonly used substrates for HIC
and the primary substrates for MCM. Usually, the A-plane (11-20)
sapphire substrates are employed.
