Technology of IR LED 950nm

The production of IR LED 950nm involves several key steps, including material growth, epitaxial layer fabrication, device fabrication, and packaging. The following is a brief overview of the technology involved in the production of 950nm IR LEDs: 1. Material Growth: The first step in producing 950nm IR LEDs is the growth of the semiconductor material, typically GaAs (Gallium Arsenide) or InGaAsP (Indium Gallium Arsenide Phosphide). The growth process involves depositing a thin layer of semiconductor material on a substrate using techniques such as molecular beam epitaxy (MBE) or metalorganic chemical vapor deposition (MOCVD). 2. Epitaxial Layer Fabrication: After the semiconductor material is grown, epitaxial layers are formed on the substrate. These layers consist of a series of quantum wells, which are responsible for the emission of infrared radiation. The thickness and composition of these layers are carefully controlled to achieve the desired emission wavelength. 3. Device Fabrication: The epitaxial layers are then processed into a diode structure by creating a p-n junction. This involves diffusing impurities into the layers to create the p-type and n-type regions, and then etching away parts of the layers to form the contact areas. 4. Packaging: Finally, the completed diode is packaged into a module, which includes a housing, lens, and electrical connections. The lens is designed to focus the emitted infrared radiation into a narrow beam, improving the device's performance.
