Manufacturing Processes in Infrared LED Factories

The manufacturing process of infrared LEDs involves several steps, including wafer fabrication, epitaxy, lithography, etching, and packaging. Here's a brief overview of these processes: 1. Wafer Fabrication: The process begins with the production of silicon wafers, which serve as the base material for LED production. These wafers are typically 200 to 300 mm in diameter and have a thickness of about 0.7 mm. 2. Epitaxy: In this step, a thin layer of gallium arsenide (GaAs) is deposited on the silicon wafer using a process called molecular beam epitaxy (MBE). This layer serves as the active region of the LED. 3. Lithography: The wafer is then subjected to lithography, a process that involves depositing a photoresist layer on the surface and exposing it to ultraviolet light. This step helps create the required patterns for the LED. 4. Etching: The exposed areas of the photoresist are etched away, leaving behind the desired patterns. This process helps shape the LED's structure. 5. Packaging: Finally, the LED is packaged using a leadless plastic or ceramic encapsulant. This step involves mounting the LED die on a substrate and attaching the necessary electrical connections.
