Technology of UV Diode LED

UV Diode LED is a semiconductor device that emits UV light when an electric current passes through it. The core material of UV LED chips is typically Gallium Nitride (GaN), which has a wide bandgap and excellent UV emission properties. The UV LED chip is encapsulated in a light-emitting package, which includes a lens, heat sink, and other components to optimize the light output and heat dissipation. The manufacturing process of UV Diode LED involves several steps, including epitaxy, wafer fabrication, chip cutting, and packaging. Epitaxy is the process of growing a thin layer of GaN on a substrate material, such as Silicon or Sapphire. Wafer fabrication involves slicing the epitaxial layer into thin wafers and then cutting the wafers into individual chips. Finally, the chips are packaged into a light-emitting package.
