Manufacturing Process

The manufacturing process of 5mm square LEDs involves several steps, starting with the creation of the semiconductor material. Here’s an overview of the process:

1. Growth of the Crystal: The first step is the growth of a single crystal of gallium nitride (GaN) or other semiconductor materials using the chemical vapor deposition (CVD) process. This crystal serves as the base for the LED.

2. Doping: The crystal is then doped with impurities to create a p-n junction, which allows for the flow of electricity and the emission of light.

3. Lithography: The crystal is coated with a photoresist, and a mask is used to expose the desired pattern. This process is known as lithography.

4. Etching: The exposed areas of the photoresist are etched away, leaving behind the desired pattern on the crystal.

5. Milling: The crystal is milled to the desired thickness and shape, in this case, a 5mm square.

6. Bonding: The milled crystal is then bonded to a metal substrate, which serves as the electrical connection and helps to dissipate heat.

7. Encapsulation: The LED is encapsulated in a protective material to prevent damage and enhance its lifespan.

8. Testing: Finally, the LED is tested for its electrical and optical properties to ensure it meets the required specifications.
