Introduction to Infrared LED Chip Industry

1. Definition and Overview of Infrared LED Chip

The infrared LED chip, also known as the infrared emitting diode, is a semiconductor device that emits infrared light when an electric current passes through it. It is widely used in various fields such as consumer electronics, automotive, medical, and industrial applications. In recent years, with the rapid development of the Internet of Things (IoT) and smart home industries, the demand for infrared LED chips has been increasing. The infrared LED chip is typically made of gallium arsenide (GaAs) or gallium nitride (GaN) as the main material. The core of the chip is the PN junction, which emits infrared light when the electric current passes through it. The infrared light emitted by the chip has a wavelength range of 700nm to 1400nm, which is invisible to the human eye.

2. Types of Infrared LED Chips

There are mainly two types of infrared LED chips: near-infrared (NIR) and far-infrared (FIR). NIR chips have a shorter wavelength, typically ranging from 700nm to 1000nm, and are commonly used in consumer electronics, such as remote controls, motion sensors, and night vision devices. FIR chips have a longer wavelength, typically ranging from 1000nm to 1400nm, and are widely used in industrial applications, such as thermal imaging, security monitoring, and medical diagnostics.

3. Key Technologies in Infrared LED Chip Manufacturing

The manufacturing process of infrared LED chips involves several key technologies, including epitaxy, lithography, etching, and packaging. The following are the main technologies involved: 1. Epitaxy: Epitaxy is the process of growing a thin layer of semiconductor material on a substrate. In the case of infrared LED chips, gallium arsenide or gallium nitride is used as the epitaxial material. The epitaxy process includes molecular beam epitaxy (MBE) and metalorganic chemical vapor deposition (MOCVD). 2. Lithography: Lithography is the process of creating patterns on the semiconductor wafer. In the case of infrared LED chips, the lithography process is used to pattern the PN junction and other key structures on the wafer. 3. Etching: Etching is the process of removing material from the wafer to form the desired structures. In the case of infrared LED chips, etching is used to remove the epitaxial layer and form the PN junction. 4. Packaging: Packaging is the process of mounting the infrared LED chip on a substrate and connecting it to external circuits. The packaging process includes wire bonding, flip-chip, and other techniques.
