I’m interested in purchasing some Sapphire Wafers that are similar to the c-plane sapphire wafers ID 1251 listed in your web site.
The question I have is, are these Double Side Polished wafers optically clear and how much reflectivity is
there? I need to use them to cover LED’s during testing and cannot afford to have an extremely reflective surface that can skew the data.
The info below is from your web page and are the wafers I’m looking at. If you can send me more info
on this product, I can have the engineering team look at it and determine if they are the correct ones for
this project.

What is a C-Plane Sapphire Wafer and what is its application?
A C-plane sapphire wafer is a thin, flat disc made from sapphire crystal with a c-plane 
orientation. The c-plane is a specific crystallographic orientation of sapphire that has a hexagonal structure, and the wafer is called c-plane because it is cut perpendicular to the c-axis.
Sapphire wafers are used in a wide range of applications, particularly in the semiconductor industry. C-plane sapphire wafers are particularly useful in the production of light-emitting diodes (LEDs), as they offer a number of desirable properties, including high transparency in the visible and near-infrared regions, excellent thermal conductivity, and high chemical and mechanical durability.
In addition to LEDs, c-plane sapphire wafers are also used in the manufacture of power electronic devices, such as diodes and transistors, as well as in the production of high-temperature and high-pressure sensors, watch faces, and other precision optics.
Sapphire is a popular choice for high-precision optical instruments. The atomic-scale properties of sapphire allow for highly accurate measurements.

What is A-Plane Sapphire?
A-plane sapphire is a high-quality material with high purity. The material is incredibly durable, making it an ideal choice for semiconductor applications. In addition, sapphire is more affordable than asymmetrical sapphire, making it an excellent material for thin-film technology. Compared to other types of materials, c-plane sapphire is also more brittle, which means that it is more prone to breakage.
In a previous experiment, researchers studied the electrical evaluation of c-plane sapphire wafers. These studies demonstrated that the majority carrier lifetime is a factor of four, which is lower than the corresponding value in silicon. In contrast, the minority carrier lifetime is about one ns3, making c-plane sapphire an excellent material for SOI devices.
Several advantages of c-plane sapphire over Si include its higher resistance. In microelectronic devices, sapphire provides better performance, reduced parasitic capacitance, and improved film carrier mobility. The materials are also highly transparent, making them suitable substrates for a wide range of applications. If the high-resistance properties of silicon aren't enough for your application, sapphire is an excellent choice for these technologies.
The material properties of c-plane sapphire are identical to those of other sapphire components. They are Mohs 9 in hardness and can be fabricated in as little as 0.4 mm. They have a transmitted wave front error of less than l/10 nm at 632.8 nm. Unlike quartz, the optical properties of c-plane sapphirite are very stable.
The study was conducted using a C-plane patterned sapphire substrate. Its full-width at half-max of c-plane sapphire was 732 nm. Its radiation hardness was found to be 612.2 nm. This makes it an ideal choice for epitaxial growth of III-V and II-VI compounds. This research demonstrates the versatility of a sapphire chip.
The c-plane sapphire is a common material used in semiconductors. The structure of c-plane sapphire is determined by its band-gap distribution. HF, SC1, and SC1 are used to treat the sapphire. The phosphate buffer layer makes it a useful material for various applications. These treatments can be used to smooth the surface of a sapphire crystal.
C-plane sapphire is also known as zero-degree sapphire or c-plane sapphire. It is the cheapest of the three types and is commonly used for high-precision optical applications. Its chemical resistance is exemplary, and its surface hardness is second only to diamond. In addition to its optical properties, a C-plane sapphire is known for its low-transmittedtransmitted wavefront distortion.
A variety of different types of sapphire are available in nature. The deep blue sapphire is a deep blue stone that contains iron and titanium. The crystalline structure of a sapphire depends on many physical properties, including temperature. A C-plane sapphire is best for applications that require optical quality. These materials are abrasive, but they are also tough and resistant to wear.
The c-plane sapphire has a high degree of anisotropy. This means that it is more resistant to scratches. The c-plane sapphire is a superior choice for laser-cutting applications. Moreover, it is highly stable, as it can withstand heat and pressure. So, if you are looking for a new type of cut to your specifications, it is well worth considering the c-plane sapphire.
A C-plane sapphire is a transparent, monocrystalline sapphire glass. It has a low density, and its high-density patterned counterparts are transparent. The c-plane is also a superior choice for microelectronics. A n-plane n-planer is an example of a n-plane n-planing.
We have a large selection of c-plane sapphire with both thick and thin wafers single and double side polished.
What are C-plane Sapphire Wafer Applications?
One of the most important characteristics of c-plane sapphire is its high optical transmittance. Its optical properties make it a perfect material for ultraviolet and near-infrared applications. C-plane sapphier are also stronger than standard glass substrates. C-plane sapphire is also resistant to high-temperature, thermal shock on the surface and scratch resistant.
C-plane sapphire wafers are transparent or opaque depending on if it's single or double side polished. It's amorphous, which means that it is transparent to light. C-plane Al2O3 is an optimal choice for microelectronics and hybrid modules. Its TDs are a key feature in high-precision photonics.
C-plane sapphire wafers are great for Infrared (IR) applications and sapphire are often used as a base wafer for growing III-V and II-VI compounds including Gallium Arsenide, and Gallium Nitride to fabricate blue LED and laser diodes.
Which Sapphire Plane is Easiest to Cleave?
A researcher requested the following:
Question:
We are planning to buy sapphire wafers and I have a few questions: - we need to cleave the wafer in squared chips. Which crystallographic orientation is better suited for this? I saw you have different possibilities. - would it be possible to buy only one or two, or the order includes a fixed number of wafers?
Answer:
Crystallographic orientation C-plane is best for cleave, to buy only one or two is ok.
