The key features of high power infrared transmitter diodes include high brightness, wide viewing angle, and stable performance.

Technology and Manufacturing Process

The manufacturing process of high power infrared transmitter diodes involves several critical steps, including epitaxial growth, wafer slicing, and device fabrication. Epitaxial growth is the process of depositing a thin layer of semiconductor material on a substrate to create a high-quality crystal structure. This step is crucial for achieving the desired optical and electrical properties of the diode.

After epitaxial growth, the wafer is sliced into individual diode chips using a diamond saw. The chips are then processed through a series of steps, including doping, etching, and metallization, to form the final diode structure. The doping process introduces impurities into the semiconductor material to create p-n junctions, which are responsible for the electrical conduction and light emission.
