There are several types of infrared LED chips available in the market, each with its own set of characteristics and applications. The most common types include:

1. AlInGaP Infrared LED Chips: These chips are known for their high brightness and long lifespan. They are commonly used in applications requiring a wide viewing angle and long-range transmission.

2. AlGaAs Infrared LED Chips: These chips are suitable for short-range applications and are known for their high efficiency and stability.

3. AlGaInAs Infrared LED Chips: These chips offer a wide range of emission wavelengths, making them versatile for different applications. They are often used in medical imaging and fiber-optic communication systems.

4. SiC Infrared LED Chips: Silicon carbide (SiC) infrared LED chips are known for their high temperature resistance and excellent performance in harsh environments. They are commonly used in industrial and military applications.

Manufacturing Process

The manufacturing process of an infrared LED chip involves several steps, including wafer fabrication, epitaxial growth, chip cutting, and packaging. Here is a brief overview of the process:

1. Wafer Fabrication: The process begins with the production of a silicon wafer, which serves as the base material for the LED chip. The wafer is typically made of high-purity silicon and is polished to a smooth surface.

2. Epitaxial Growth: Epitaxial growth is a crucial step in the manufacturing process. It involves depositing a thin layer of semiconductor material on the wafer surface using techniques like molecular beam epitaxy (MBE) or metalorganic chemical vapor deposition (MOCVD). This layer forms the active region of the LED chip.

3. Chip Cutting: After the epitaxial growth, the wafer is cut into individual chips using a laser or a diamond saw. The size and shape of the chips depend on the specific application requirements.

4. Package: The final step is packaging the LED chip. This involves attaching the chip to a lead frame, which provides electrical connections and thermal management. The package is then sealed to protect the chip from external elements.
