Production Process

Key Steps in Infrared LED Manufacturing

The production of infrared LEDs involves several key steps, from raw material acquisition to the final product assembly. Below is an overview of the typical production process in an infrared LED factory:

1. Material Preparation: The first step is to acquire high-purity raw materials, such as gallium arsenide (GaAs) and gallium nitride (GaN), which are essential for the fabrication of infrared LEDs.

2. Epitaxy: In this step, a thin layer of GaAs or GaN is grown on a substrate using a process called molecular beam epitaxy (MBE) or metalorganic chemical vapor deposition (MOCVD). This layer serves as the active region of the LED.

3. Doping: The epitaxial layer is doped with impurities to create p-n junctions, which are essential for the generation and confinement of electrical charge carriers.

4. Photolithography: A mask is used to pattern the epitaxial layer, creating the desired structure of the LED.

5. Etching and Cleaning: The patterned layer is etched to form the LED’s p-n junction and then cleaned to remove any impurities.

6. Metalization: A thin layer of metal is deposited on the etched surface to provide electrical contact.

7. Bonding: The metalized layer is bonded to a metal substrate using a high-temperature process.

8. Encapsulation: The LED is encapsulated in a transparent or semi-transparent material to protect it from environmental factors and enhance its optical properties.

9. Testing and Sorting: The final step involves testing the LED for electrical and optical characteristics and sorting them based on their performance.
