What size is sapphire substrate?

Sapphire substrate is a type of substrate made from sapphire crystal, which is commonly used in various industries, including electronics, optics, and semiconductor manufacturing.

Sapphire substrates come in various sizes, and the size of a sapphire substrate typically depends on the application for which it is intended.

 The most common sizes of sapphire substrates used in the semiconductor industry are 2-inch, 4-inch, and 6-inch diameters.

The size of the substrate is important for the fabrication of semiconductor devices, as the larger the substrate, the more chips can be produced at once, resulting in greater efficiency and cost savings.

In addition to the standard sizes, sapphire substrates can also be customized to meet specific application requirements.

For example, sapphire substrates can be cut into various shapes, including square, rectangular, and circular shapes, depending on the specific application.

The thickness of sapphire substrates also varies depending on the application. In the semiconductor industry, the typical thickness of a sapphire substrate is around 350 microns, although thicker substrates are also available for certain applications.

Thinner substrates are used for applications that require flexibility, such as in the production of flexible displays.

In the optics industry, sapphire substrates are used for the production of lenses and other optical components.

In this industry, sapphire substrates are typically larger in size, with diameters of up to 12 inches and thicknesses ranging from a few hundred microns to several millimeters.

 Overall, the size of a sapphire substrate is dependent on the specific application and can vary widely, from a few millimeters to several inches in diameter.

Sapphire substrates can also be customized to meet specific requirements, including shape, thickness, and orientation, making them a versatile material for a wide range of industries.
