Exceptional Surface Quality and Mechanical Strength

Our sapphire wafers are meticulously polished to achieve surface roughness below 0.5 nm, ensuring minimal optical scattering for applications demanding high transparency and precise performance. Their high mechanical strength and Mohs hardness of 9 make them exceptionally durable for both laboratory and industrial environments.


Tailored Dimensions and Orientations

We offer a range of sizes from 2 to 6 inches, along with custom shapes (round, square, or bespoke) and orientations like C-plane (0001), A-plane, and R-plane. Our tight thickness tolerance (0.01 mm) and edge finishing options cater to the distinct needs of your application, ensuring optimal fit and performance.


Versatility Across Critical Industries

Sapphire wafers stand out for high thermal conductivity (2546 W/(mK)), superior optical transparency, and resistance to chemical corrosion. These qualities make them a preferred substrate for LEDs, optical devices, semiconductors, and even luxury watch glasses, providing reliability and long-term value.

FAQs of SAPPHIRE WAFERS:


Q: How are sapphire wafers typically used in the semiconductor and optics industries?

A: Sapphire wafers serve as critical substrates for LEDs, optical devices, and semiconductor components, offering exceptional transparency, high thermal conductivity, and impressive mechanical strength. Their chemical inertness and stability under high temperatures make them ideal for such demanding uses.

Q: What are the benefits of choosing sapphire wafers with a C-plane (0001) orientation?

A: Selecting a C-plane (0001) orientation provides optimal lattice matching and flatness, which enhances epitaxial growth for LEDs and other semiconductor devices, leading to improved device performance and greater manufacturing yield.

Q: When should I opt for custom shapes or orientations for sapphire wafers?

A: Custom shapes and orientations are recommended when standard options do not fit the specific technical requirements of your project. Applications with unique mounting needs or precise optical alignment often benefit from bespoke design and fabrication.

Q: Where can sapphire wafers be sourced with cleanroom packaging and high purity in India?

A: Indian manufacturers and suppliers provide sapphire wafers with 99.9% purity, packed in cleanroom-grade single wafer containers to ensure contamination-free delivery suitable for sensitive industrial and laboratory applications.

Q: What is the process followed to ensure the surface roughness is less than 0.5 nm?

A: Advanced polishing techniques, combined with rigorous quality control, are employed to achieve ultra-smooth surfaces on sapphire wafers. Specialized equipment measures and verifies that the surface roughness consistently remains below 0.5 nm.

Q: How does high thermal conductivity benefit the usage of sapphire wafers?

A: The high thermal conductivity of sapphire (2546 W/(mK) at room temperature) allows efficient heat dissipation during device operation, which is crucial for the longevity and performance stability of LEDs, laser devices, and electronic components.
