Epitaxial Growth: The first step in manufacturing 10mm UV LED diodes is epitaxial growth, where a thin layer of GaN is deposited on a substrate material, such as sapphire or silicon carbide. This process is carried out in a vacuum chamber using metalorganic chemical vapor deposition (MOCVD) or molecular beam epitaxy (MBE) techniques. 2. Wafer Fabrication: After epitaxial growth, the GaN wafer is subjected to various processes, including doping, etching, and polishing. Doping involves introducing impurities into the GaN layer to alter its electrical properties. Etching is used to create the desired structure, such as the p-n junction, while polishing ensures a smooth surface for the subsequent packaging process. 3. Packaging: The final step in manufacturing 10mm UV LED diodes is packaging, which involves encapsulating the diode in a protective material and connecting it to external circuitry. Common packaging materials include epoxy, silicone, and phosphor-based materials. The packaging process also involves thermal management to ensure the diode operates within its specified temperature range.
