 If you happen to be looking for Sapphire wafer substrate manufacturers for LED power semiconductor, watch glass and sapphire wafers for other sapphire substrates, it is a right decision for you to contact us, because we are constantly researching and exploring the manufacture of sapphire wafers, and I believe we can help you.

What are Some Sapphire Applications?

In fact, the application range of sapphire wafer is extremely wide. It can not only be applied to the electronic field, but also the planar sapphire substrate has been used in the photoelectric field for decades, such as microscopes, flat panel displays, etc.

That is to say, any surface application of sapphire wafer can be involved. By placing an electrode in the substrate, a thin metal oxide layer can be created, Absorb all ultraviolet rays that shine on the display or microscope. As a result, the human eye cannot see them at all.

Now science is promoting these planes, which are basically used in the photovoltaic field, such as creating solar cells and solar concentrators.

So at present, sapphire is not only used in some scientific fields, but also used in some engagement rings as a common application.

In terms of scientific application, it mainly depends on planar sapphire, which can be used in photoelectric effect measurement, fluorescence and chemical analysis. It is mainly because sapphire has a very obvious feature that it allows most colors to pass through, Why is that?

Sapphire can be an engagement ring. The reason why it can be used is that it can be transparent or opaque.

Although it is impossible to make various colors on sapphires for engagement rings at present, we can see from the color perspective that sapphires from yellow green to blue white are also commonly used as rubies and emeralds. Of course, it is the most common application designed for watches and cuffs.

Sapphire Window Orientations

 At present, there are two main ways to develop sapphires for optical applications. One is called m axis, and the other is called 2 Axis. Android is relatively complex.

It involves relatively accurate crystal arrangement, which is composed of ordinary elements. There is a flat chisel in the center to align with a specific rotation axis. It is usually called square angle alignment, also called wave plate, which is the principle of generating a high quality diagram line from a plane circle.

The two sapphires are basically based on the same optical measurement.That is, birefringence.

This refraction method is used to measure the crystal imbalance when light waves hit the light source. The best measurement of birefringence is when the crystal is completely spherical.

Because crystals close to the spherical shape have higher birefringence than those slightly irregular crystals, high birefringence can improve the clarity of the image generated by sapphire, and improving its brightness is conducive to better color performance.

 The key reason for the influence of sapphire crystal orientation is the stimulation of sapphire crystal and whether the top surface is flat?When a photographer chooses a fast lens, the faster the lens is, the clearer the image will be. This is why they must consider sapphire and its direction.

 The S angle is an important attribute of sapphire. It indicates the direction of the crystal on a plane with observation windows overlapping.

In short, when the observation window coincides with the symmetry plane of the sapphire, the birefringence is balanced. When the window and the gemini are not coincident, the sapphire will show positive birefringence.

Epitaxial wafers are a special layer of semiconductor wafers once on a wafer substrate. They have better performance than non epitaxial wafers in some fields. For example, in a more complex environment, they can prevent non hardening and reduce noise, and can provide better device bias matching.

However, in terms of price, EPI wafer sources are more expensive. Epitaxial wafers involve a kind of vegetable. The necessary crystals are grown on another or the same epitaxial material on the wafer.

Sapphire Windows (Al2O3) epi-polished all specs in stock

 In general, when specific light is added to the detector, the color and brightness of natural sapphire will change, and tend to develop in a strong direction.

It has a single crystal instead of two or more crystals. Another advantage is that detectors equipped with infrared lamps at very low intensity are much more efficient than traditional products in resolving light.

The birefringence of a modern sapphire window is much thinner than in the past, and its thickness depends on the optical resolution required by the detector.

The current design makes it more prone to distinguish light at lower power than in the past. Even if the optical system becomes thinner, the quality of the final results has been improved.

A sapphire window with a single chip, rather than two or more chips, will provide more than it was made. Better optical resolution of the detector.

No matter from which direction, the refractive index of the crystal is completely different.

No matter what angle we look at the crystal from, we will have the same refractive index because of the same optical characteristics. Sapphire crystals will not refract light in an ideal way, because only one edge is 0.

Sapphire Windows (Al2O3) 

What is Natural Sapphire?

Sapphire has the highest temperature grade among all optical materials. It can withstand a temperature of 1700 ℃ while still being flat. Sapphire windows can also resist chemical substances.

Although sapphire is not as resistant as quartz or fused quartz, it is the best choice for sensitive electronic components. Therefore, it is the best choice for filters in laboratories, medical instruments and industrial instruments.

Although the sapphire window is very durable, the cost of this process is relatively low. It usually cuts the sapphire into windows while retaining the natural source.

This process mimics the natural formation process of sapphire. The sapphire seed crystal is placed under high temperature and pressure, and it can withstand a lot of heat without cracking or disintegration.

Despite these advantages, the synthetic sapphire window is more expensive than the natural one.  At present, sapphire is the main raw material in glasses, cameras, lenses, microscope lenses, even military equipment and testing instruments, because it has the ability to resist abrasion and scratches. For example, sapphirere g .

 Sapphire is sturdy, durable and thermal efficient. It is elastic to wear chemicals and scratches. Its hardness is very high. Sapphire windows are usually much thinner than glass or metal beds, and their service life is also very long. So if you need a more durable window material, you can choose or consider sapphire.

What is Synthetic Sapphire?

Synthetic sapphires are grown under experimental conditions, not in natural environments. In fact, they have the same chemical composition as natural sapphires in terms of raw materials.

Sapphires grown in the laboratory are artificial gemstones grown under controlled conditions in the laboratory.

Their chemical properties, physical properties and optical properties are similar to those of natural counterparts, which makes the sapphires created in the laboratory become real gemstones.

The process of artificial creation means that they can have little or no inclusions, that is, no other impurities, and usually appear completely clean under falling sound, They can also be different in color and saturation.

Natural gems are found and mined on the earth. They form different impurities through natural processes, which will lead to different color clarity and shapes.

Gems cultivated in the laboratory are ecologically friendly and humanized, because they are not mined.

What is natural sapphire?

Natural sapphire is a sapphire crystal formed underground. Its color and clarity are produced through heating.

It is not uncommon for processed sapphires to never appear naturally in the displayed sapphires. It is our goal to find an unlimited number of sapphires in the world.

Of course, natural sapphire is a raw material that has not been treated, which is different from the sapphire developed in the laboratory.

In addition to its physical properties, a-plane sapphire wafers also possess excellent electrical insulation properties.

This property makes a-plane sapphire wafer well-suited for applications where electrical isolation is crucial, such as in electronic devices or power systems, where it is essential to prevent unwanted electrical leakage.

A-plane sapphire wafers exhibit low dielectric loss. It has minimal energy dissipation when subjected to an alternating electric field.

This is advantageous in applications that require high-frequency operation or efficient transmission of electrical signals. It helps to minimize signal loss and maintain signal integrity.

C-Plane Sapphire Wafer

C-plane sapphire wafer refers to a sapphire crystal that has been cut and polished in a c-plane orientation. By slicing the sapphire crystal perpendicular to the c-axis, a flat and smooth surface is created.

The c-plane sapphire wafer has a high degree of crystallographic symmetry, which can be advantageous in certain device fabrication processes.

The consistent and well-defined crystal structure enables precise alignment and deposition of materials. It ensures accurate and controlled manufacturing of electronic and optoelectronic devices.

Wafer-scale single-crystal monolayer graphene grown on a sapphire substrate makes a big impact in graphene synthesis.

The single crystal sapphire substrate in c-plane wafers provides an excellent template for the epitaxial growth of graphene. This makes the formation of a uniform and continuous monolayer across the entire wafer.

R-Plane Sapphire Wafer

R-plane sapphire wafers denotes a crystallographic orientation in which the sapphire wafer is cut along a specific plane.

R-plane wafer sapphire are oriented perpendicular to the R-axis, which is one of the crystallographic axes in the hexagonal lattice structure of sapphire.

R-plane sapphire wafers lies in their compatibility with hetero-epitaxial deposition of silicon. Hetero-epitaxy involves the deposition of a thin layer of one material onto the surface of another material with a different crystal structure. Silicon can be epitaxially grown on the wafer surface.

This creates a highly controlled and precise interface between the sapphire and silicon layers.

Sapphire Wafer Properties

Sapphire wafers possess a combination of desirable properties. These properties make sapphire glass wafers highly versatile and suitable for numerous applications in industries such as optics, electronics, semiconductor manufacturing, and high-power systems.

Sapphire wafers has exceptional high temperature resistance. They can withstand elevated temperatures without experiencing significant degradation or structural changes. This makes sapphire wafers suitable for applications that involve high heat environments like high-power electronics.

Sapphire wafers also exhibit excellent thermal shock resistance, meaning they can withstand rapid temperature changes without cracking or fracturing. This property is crucial in environments where sudden temperature fluctuations occur.

Sapphire glass wafers are characterized by their high strength and scratch resistance. It is one of the hardest materials ranking just below diamond on the Mohs scale of hardness.

Sapphire Wafer Key Features

Sapphire wafers has high purity exceeding 99.995%. This ensures minimal impurities within the material, allowing for excellent optical performance and efficient transmission of light.

The university wafer sapphire has the ability maintaining the clarity and transparency required for optical applications in a broad wavelength range.

It also has superior strength when compared to standard glass substrates. Sapphire is renowned for its exceptional hardness and durability. It is significantly stronger and more resistant to scratches, impacts, and wear than traditional glass substrates like quartz.

It also has a high melting point of approximately 2030°C. It can withstand elevated temperatures without undergoing significant structural changes or degradation.

What are Sapphire Waveplates?

The primary function of a sapphire waveplate is to convert linearly polarized light into elliptically or circularly polarized light.

This conversion is achieved by exploiting the birefringent properties of sapphire. The sapphire wafer cost a little because it has different refractive indices along different crystallographic axes.

The sapphire waveplate is designed as a thin plate made of sapphire crystal. It exhibits birefringence due to its anisotropic nature. When linearly polarized light passes through the waveplate, the two orthogonal components of the light experience different refractive indices.

This results in a phase difference between them. This phase difference causes the polarization of the light to be altered, leading to a change in its polarization type.

By carefully selecting the thickness of the sapphire waveplate, the wavelength of the incident light, and the desired phase shift, the waveplate can be optimized to achieve specific polarization manipulation effects.

For example, a quarter-wave plate introduces a phase shift of 90 degrees between the orthogonal components of the incident light, converting linear polarization into circular polarization, or vice versa.

A half-wave plate introduces a phase shift of 180 degrees, which can convert linear polarization to its orthogonal direction or transform circular polarization into linear polarization with a specific orientation.

Why Use Sapphire for Wafer Carriers?

The primary reasons for using sapphire as a material for wafer carriers is its higher thermal conductivity.

Sapphire exhibits a thermal conductivity of approximately 42 W/mK at 20°C, which is significantly higher than many other materials commonly used in wafer carriers.

Sapphire boasts a higher melting temperature compared to other materials used for wafer carriers. With a melting point of approximately 2040°C, sapphire can withstand high-temperature processes without undergoing significant deformation or damage.

This makes sapphire wafer carriers suitable for applications that involve elevated temperatures.

Sapphire offers good mechanical strength, thanks to its off-axis crystal growth. The off-axis crystal growth technique allows for customized fabrication of sapphire wafer thickness can be as thin as 0.4572 mm (or 18 mils).

This flexibility in fabrication enables the production of thin and lightweight wafer carriers while maintaining structural integrity and mechanical stability.

Advantages of Sapphire over Quartz Wafer Carriers

The superior hardness of sapphire ensures that it remains robust and resilient to scratches or abrasions, providing a reliable and protective surface for the wafers. This makes sapphire wafer cleaning easier.

Quartz wafer carriers may be more susceptible to scratches or wear, which can compromise the quality and integrity of the wafers.

Transparency is another notable advantage of sapphire wafer carriers. Sapphire exhibits excellent optical transparency across a wide range of wavelengths, including the ultraviolet, visible, and near-infrared regions.

This transparency allows for better visibility and monitoring of the wafer during processing, facilitating precise alignment and inspection.

Sapphire wafer carriers are highly durable and capable of withstanding repeated use and handling which is advantageous for sapphire wafer suppliers.

Sapphire’s inherent mechanical strength and resilience make it resistant to mechanical stresses, impacts, and thermal cycling. This durability ensures that sapphire wafer carriers can endure the rigors of wafer processing environments, including handling, transport, and various mechanical forces, without experiencing degradation or failure.

Though the sapphire wafer price cost a little bit more than glass or quarts wafer carriers.

An Indispensable Component in Mass LED Production
