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
We currently provide customers with standardized 10x10mm/Φ10mm/Φ15mm/Φ20mm/Φ25.4mm/Φ30mm/Φ50.8mm high quality nitrogen
Aluminum single crystal substrate products, and can also provide customers with 10-20mm non-polar
M-plane aluminum nitride single crystal substrate, or customize non-standard 5mm-50.8mm to customers
Polished aluminum nitride single crystal substrate. This product is widely used as a high-end substrate material
Used in UVC-LED chips, UV detectors, UV lasers, and various high power
/High temperature/high frequency electronic device field.
