sapphire wafer

A sapphire wafer is a thin, flat piece of sapphire crystal used in the manufacturing of electronic components, particularly in advanced devices like smartphones and LED lights. Sapphire is a very hard, durable, and optically transparent material, making it ideal for precision applications. These wafers serve as a foundational substrate onto which other materials, such as semiconductor layers, are grown or assembled during production. Their high performance and stability enable the creation of durable, high-quality electronic and optical components, contributing to the durability and functionality of modern technology.
