This article aims to provide an in-depth introduction to the 850nm IR LED industry, covering its technology, applications, market trends, and future prospects.

Technology and Production of 850nm IR LED

The 850nm IR LED is a type of semiconductor device that emits infrared light with a wavelength of 850 nanometers. It is primarily made of gallium arsenide (GaAs) or gallium indium phosphide (GaInP) materials, which are known for their excellent infrared emission properties. The production process of 850nm IR LED involves several steps, including material growth, epitaxial layer fabrication, wafer slicing, and device packaging.

Material growth: The first step in producing 850nm IR LED is the growth of high-quality semiconductor materials. This is typically achieved through the molecular beam epitaxy (MBE) or metalorganic chemical vapor deposition (MOCVD) techniques. These methods allow for the precise control of material composition and crystal structure, which is crucial for achieving high-performance IR LEDs.

Epitaxial layer fabrication: After the semiconductor materials are grown, epitaxial layers are deposited on a substrate to form the active region of the LED. This process involves the controlled deposition of multiple layers of different materials, which determines the optical and electrical properties of the LED.

Wafer slicing: The epitaxial layers are then sliced into thin wafers, which serve as the basis for device fabrication. This process requires high precision and cleanliness to ensure the quality of the wafers.

Device packaging: The final step is the packaging of the LED wafer into a functional device. This involves mounting the wafer onto a substrate, bonding the contacts, and encapsulating the device to protect it from environmental factors. The packaging process is crucial for ensuring the reliability and stability of the 850nm IR LED.
