Product Description

Product Description:

  Sapphire wafers are highly valued in the semiconductor industry for their excellent compatibility with various epitaxial processes, including those involving III-V nitrides, superconductors, and magnetic films. Their low lattice mismatch with these materials and robust physical and chemical properties make them ideal for complex applications such as non-polar and semi-polar GaN, ZnO, and AlN epitaxial growth, as well as for the production of various semiconductor thin films. Additionally, their usage extends to applications like Silicon On Sapphire (SOS) and as optical windows. Made from high-purity (99.999%) single-crystal aluminum oxide (Al₂O₃), these wafers exhibit superior surface roughness, flatness, and cleanliness, qualities that are essential for ensuring optimal performance in both semiconductor fabrication and optical applications. If you need a dependable supplier of top-quality sapphire wafers, reaching out to a specialized provider would be beneficial.

Continuing from this, it's important to highlight that the use of sapphire wafers underpins many advanced technological applications. Their inherent properties reduce defects in epitaxial films, which is crucial for enhancing the efficiency and performance of electronic and optical devices. As technology evolves, the role of sapphire wafers continues to expand, reinforcing their position as a critical component in the cutting-edge fields of materials science and engineering.

C-plane sapphire substrates are extensively utilized for the deposition of wide-bandgap nitrides and oxide semiconductor materials, such as Gallium Nitride (GaN), Aluminum Nitride (AlN), Indium Nitride (InN), Zinc Oxide (ZnO for ultraviolet light emission), and Tin Oxide (SnO2 for ultraviolet luminescent materials). These substrates are particularly favored due to their excellent compatibility with III-V and II-VI compound semiconductors.

Additionally, standard C-plane (0001) sapphire substrates are widely employed in the fabrication of white and blue LEDs, as well as ultraviolet and deep-ultraviolet LED epitaxial layers using techniques such as Metal Organic Chemical Vapor Deposition (MOCVD) and Molecular Beam Epitaxy (MBE). They are also used in Plasma Enhanced Chemical Vapor Deposition (PECVD) for epitaxial growth.

Moreover, standard sapphire substrates serve various high-tech applications including as substrates for Heterojunction Bipolar Transistors (HBTs), Laser Diodes (LDs), and ultraviolet detectors. They are also used as substrates for nanotubes and as heat dissipation materials in high-temperature, high-power, high-frequency electronic devices. This versatility makes sapphire substrates a critical component in advancing modern technological solutions across various industries, from renewable energy to advanced electronics and photonics, reflecting their pivotal role in enabling innovative, high-performance applications.



The sapphire wafers provided by Zhiming Technology are crafted from 99.999% high-purity, single-crystal Al2O3 optical grade materials, ensuring exceptional quality. Utilizing specialized Chemical Mechanical Polishing (CMP) techniques, we achieve a cost-effective and superior performance with surface roughness of less than 0.2 nm on the C-plane and less than 0.5 nm on other planes including A, M, R, N, V, and 10-14 planes. Each wafer undergoes a rigorous cleaning process using ultra-pure water with a resistivity greater than 18 MΩ*cm in a Class 100 cleanroom, guaranteeing the highest levels of cleanliness.

To maximize research flexibility for our clients, the wafers are available packaged either as 25 pieces per box or individually. Each wafer is uniquely serialized for traceability, ensuring accountability and quality assurance throughout the supply chain. The wafers are packaged in compact and sturdy cardboard boxes to ensure safe transport and cost savings. With standard sizes typically in stock, we are committed to rapid delivery.

As a leading supplier of sapphire wafers, Zhiming Technology is dedicated to providing the best products and services, utilizing our technology to benefit the global community. Our focus is on continuous innovation and customer satisfaction, striving to meet the specific needs of researchers and industry professionals worldwide.


Packing and Shipping:

Individual packaging is a crucial aspect of product delivery, particularly for delicate items like sapphire substrates. Each substrate is meticulously enclosed in a custom-fitted protective casing to prevent any physical damage during transit. This casing usually involves anti-static materials and cushioning to shield the substrate from scratches, impacts, and electrostatic discharges. The substrate is then placed in a single, securely sealed package, often with a desiccant to control humidity. This packaging approach not only ensures the substrate reaches the client in pristine condition but also simplifies handling and storage upon arrival. Individual packaging is particularly beneficial for high-value components, ensuring that each piece retains its integrity and quality from manufacturing to end-use application
