2inch 4iinch 6Inch Sapphire based AlN templates AlN film on sapphire substrate sapphire window sapphire wafer
Applications of AlN template
Silicon-based semiconductor technology has reached its limits and could not satisfy the requirements of future
electronic devices. As a typical kind of 3rd/4th-generation semiconductor material, aluminum nitride (AlN) has
superior physical and chemical properties such as wide bandgap, high thermal conductivity, high breakdown filed,
high electronic mobility and corrosion/radiation resistance, and is a perfect substrate for optoelectronic devices,
radio frequency (RF) devices, high-power/high-frequency electronic devices, etc.. Particularly, AlN substrate is the
best candidate for UV-LED, UV detectors, UV lasers, 5G high-power/high-frequency RF devices and 5G SAW/BAW
devices, which could widely be used in environmental protection, electronics, wireless communications, printing,
biology, healthcare, military and other fields, such as UV purification/sterilization, UV curing, photocatalysis, coun
terfeit detection, high-density storage, medical phototherapy, drug discovery, wireless and secure communication,
aerospace/deep-space detection and other fields.
we have developed a serials of proprietary processes and technologies to fabricate
high-quality AlN templates. At present, Our OEM is the only company worldwide who can produce 2-6 inch AlN
templates in large-scale industrial production capability with capacity of 300,000 pieces in 2020 to meet explosive
market demand from UVC-LED, 5G wireless communication, UV detectors and sensors etc
Our OEM has developed a serials of proprietary technologies and the-state-of-the art PVT growth reactors and facilities to
fabricate different sizes of high-quality single crystalline AlN wafers, AlN temlpates. We are one of the few world-leading
high-tech companies who own full AlN fabrication capabilities to produce high-quality AlN boules and wafers, and provide
professional services and turn-key solutions to our customers,arranged from the growth reactor and hotzone design,
modeling and simulation, process design and optimization, crystal growth,
wafering and material characterization. Up to April 2019, they have applied more than 27 patents (including PCT).
