Manufacturing Process

The manufacturing process of 12v diodes involves several steps, including wafer preparation, epitaxy, doping, diffusion, and metallization. Here's a brief overview of the process:

1. Wafer Preparation: High-purity silicon wafers are prepared by slicing a silicon ingot into thin, round disks.
2. Epitaxy: The wafer is then subjected to epitaxy, a process that involves growing a thin layer of semiconductor material on the wafer surface.
3. Doping: The wafer is doped with impurities to create the desired electrical properties of the diode. The doping process can be diffusion or ion implantation.
4. Diffusion: In the diffusion process, a chemical or gas is used to introduce impurities into the silicon wafer, creating the desired electrical properties.
5. Metallization: The wafer is then metallized, which involves depositing a thin layer of metal on the wafer surface to form the electrical connections.
6. Testing: The final step is testing the diodes to ensure they meet the required specifications.
