Manufacturing Process of IR LED 950nm

The manufacturing process of IR LED 950nm involves several key steps:

1. Crystal Growth: The first step is to grow a high-quality gallium arsenide (GaAs) crystal, which serves as the substrate for the LED. This is typically done using the MBE (Molecular Beam Epitaxy) or MOCVD (Metal Organic Chemical Vapor Deposition) techniques.
2. Epitaxial Growth: After the crystal is grown, an epitaxial layer is deposited on the substrate. This layer consists of several quantum wells, which are responsible for the emission of infrared light. The thickness and composition of these quantum wells are carefully controlled to achieve the desired emission wavelength.
3. Device Fabrication: The epitaxial layer is then patterned and etched to create the LED structure. This involves the formation of the p-n junction, which generates the electrical current that excites the quantum wells and produces infrared light.
4. Mounting and Packaging: Finally, the LED is mounted on a substrate and packaged to protect it from external factors such as moisture and heat. The packaging process also involves the connection of the LED to the external circuitry.
