From consumer electronics to industrial automation, infrared LED chips play a vital role in enhancing the functionality and efficiency of devices. This article aims to provide an in-depth introduction to the infrared LED chip industry, covering its history, technology, applications, and future prospects.

History of Infrared LED Chips

The development of infrared LED chips dates back to the early 20th century when scientists began exploring the properties of semiconductors. In the 1960s, the first practical infrared LED was developed, marking the beginning of a new era in optoelectronics. Over the years, advancements in semiconductor technology have led to the miniaturization and improvement of infrared LED chips, making them more efficient and cost-effective.

Technology of Infrared LED Chips

Infrared LED chips are made of semiconductor materials, typically gallium arsenide (GaAs) or gallium nitride (GaN). These materials have a direct bandgap, which allows them to emit infrared light when an electric current is applied. The manufacturing process involves several steps, including epitaxy, lithography, and packaging.

Epitaxy

Epitaxy is the process of growing a thin layer of semiconductor material on a substrate. In the case of infrared LED chips, the epitaxial layer is grown on a gallium arsenide or gallium nitride substrate. This layer contains a p-n junction, which is responsible for generating and emitting infrared light.

Lithography

Lithography is the process of creating a pattern on the epitaxial layer. This pattern determines the shape and size of the LED chip. The pattern is transferred onto the epitaxial layer using a photomask and a photolithography process.

Packaging

After the lithography process, the LED chip is packaged to protect it from external factors and to facilitate its integration into electronic devices. Packaging involves encapsulating the chip in a housing and connecting it to external circuitry using leads or bonds.
