Sapphire Substrate

A sapphire substrate is a piece of solid, transparent material made from synthetic sapphire, which is a very durable form of aluminum oxide. In electronics, it serves as a foundation or “base plate” for building high-tech devices like LEDs and semiconductors. Its excellent thermal stability, durability, and optical properties make it ideal for supporting and insulating delicate electronic components. Essentially, it provides a stable, high-quality surface to ensure the efficient and reliable performance of advanced electronic and optical devices.
