2 inch monocrystalline sapphire wafer double sides polished Al2O3
99.999% single crystal substrate
Product description
Sapphire wafer is a common substrate for the preparation of III-V
nitrides, superconductors and magnetic epitaxial films due to its
low lattice mismatch and good physical and chemical stability. It
is widely used in GaN/ZnO/AIN non-polar and half-order epitaxial
growth, various semiconductor thin films epitaxial growth, Silicon
On Sapphire, optical window, etc.
We all use optical primary crystal materials, all raw materials are
99.999% high purity single crystal Al₂O₃, the production of
sapphire wafers with excellent surface roughness, flatness and
cleanliness, can be directly applied to semiconductor film
epitaxial growth, optical window and so on.

Packaging and shipping services
Our sapphire wafer products are individually packaged in small
boxes, each containing 25 pieces of sapphire. This packaging is
designed to ensure the safety and protection of each piece of
sapphire, while facilitating storage and transportation. Each small
box is carefully designed to ensure that the sapphire pieces will
not collide with each other or be affected by the outside world.
Such packaging not only ensures the integrity and quality of
sapphire, but also provides customers with convenient use and
management. We are committed to providing our customers with the
highest quality sapphire products and ensure that every sapphire is
properly cared for in the packaging to meet the needs and
expectations of our customers.
Product application
1. Optoelectronics:
Sapphire wafers play a pivotal role in the optoelectronics
industry. Their transparency and durability make them ideal
substrates for light-emitting diodes (LEDs), laser diodes, and
optical windows. The superior optical properties of sapphire
contribute to the efficiency and performance of these devices.
2. Aerospace and Defense:
The hardness and resilience of sapphire wafers find applications in
aerospace and defense technologies. They are used in components
such as sensor windows and protective coverings for electronic
systems, providing robust solutions in demanding environments.
3. Consumer Electronics:
With the growing demand for high-performance and durable electronic
devices, sapphire wafers are increasingly being used in the
production of smartphone camera lenses and touchscreens. Their
scratch-resistant nature enhances the longevity and visual clarity
of these components.
4. Semiconductor Manufacturing:
Sapphire wafers are gaining traction in semiconductor
manufacturing, especially for power electronics. Their thermal
conductivity and electrical insulation properties make them
suitable for applications like gallium nitride (GaN) power devices.
