substrate AlN single crystal wafers
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
