The XAJD diamond technology research team has made significant progress and breakthroughs in the industrialization of single crystal diamond substrate technology.
The single crystal diamond substrate developed by the company is mainly aimed at the fourth generation semiconductor materials, devices, and 5G communication industries, which is of great significance for improving the level of China's semiconductor materials and devices industry and promoting the replacement of new generation semiconductor technologies.
In the principle of semiconductor preparation, the substrate is a wafer made of semiconductor single crystal material, and different substrate materials can produce semiconductor chips including single crystal diamond.
Single crystal diamond is known as the "ultimate semiconductor", which is a single substance semiconductor like silicon. Its performance completely surpasses existing semiconductors and can overcome the bottlenecks of "insufficient breakdown field strength" and "self heating effect". Single crystal diamond has unique advantages in electronic devices that operate at ultra-high voltage, ultra-high current, ultra-high power, high efficiency, radiation resistance, and ultra-high frequency without the need for cooling.
As an expert in the research of single crystal diamond wide bandgap semiconductor materials and devices in China for a long time, Dr Wang led his team to independently develop a series of single crystal diamond microwave plasma chemical vapor deposition equipment with independent intellectual property rights after long-term scientific research and development. He has mastered relevant technologies and has fully completed theoretical innovation, laboratory experimental research, and pilot testing
At present, the company can quantitatively provide 1-2 inch large-area high-quality single crystal diamond substrates, effectively ensuring the demand for high-quality and large-sized electronic grade single crystal diamonds in China and international power electronic devices, thermal conductivity, radar detection and other fields, while also meeting the demand for high-quality crystal seeds in academic research.
