With the rapid development of the electronics industry, infrared receiver diode has become an indispensable component in various applications. As a key part of the infrared communication system, the infrared receiver diode plays a crucial role in converting infrared signals into electrical signals, ensuring the smooth transmission of information. In this article, we will introduce the industry of infrared receiver diode manufacturers, including their production process, market trends, and future development prospects.

Introduction to Infrared Receiver Diode

An infrared receiver diode, also known as an IR receiver diode, is a semiconductor device that converts infrared radiation into electrical signals. It is widely used in consumer electronics, home appliances, and industrial automation fields. The main functions of the infrared receiver diode include signal detection, signal conversion, and signal amplification. The working principle of the infrared receiver diode is based on the photoelectric effect. When the infrared radiation is incident on the diode, the photons with energy greater than the bandgap of the semiconductor material will be absorbed by the material, generating electron-hole pairs. These electron-hole pairs will be separated by the internal electric field of the diode, resulting in a current flow, which is the electrical signal output by the diode.

Production Process of Infrared Receiver Diode

The production process of an infrared receiver diode mainly includes the following steps: 1. Crystal growth: The crystal growth process is the first step in the production of an infrared receiver diode. The main methods of crystal growth include Czochralski method, Bridgman method, and so on. The quality of the crystal directly affects the performance of the diode. 2. Crystal cutting: After the crystal is grown, it needs to be cut into a suitable shape, such as a wafer. The cutting process can be divided into two types: slicing and grinding. The slicing process is used to obtain a flat surface, while the grinding process is used to remove the excess material. 3. Doping: The doping process is to introduce impurities into the semiconductor material to adjust its electrical properties. The doping elements commonly used in the production of infrared receiver diodes include boron, phosphorus, and arsenic. 4. Etching: The etching process is to remove the unnecessary material on the wafer, such as the protective layer and the diffusion layer. The etching method can be divided into wet etching and dry etching. 5. Diffusion: The diffusion process is to introduce the active material into the semiconductor material, so as to form the PN junction. The diffusion process can be divided into ion implantation, diffusion in the melt, and so on. 6. Iridizing: The iridizing process is to deposit a layer of metal film on the surface of the wafer, which can improve the adhesion of the subsequent film and enhance the anti-reflection performance. 7. Photoetching: The photoetching process is to use photoresist to protect the necessary parts of the wafer and then etch the unnecessary parts. 8. Wire bonding: The wire bonding process is to connect the PN junction with the lead wire, so as to form the electrical connection of the diode. 9. Packaging: The packaging process is to encapsulate the diode into a shell, which can protect the diode and facilitate the application.
