New semiconductor materials are expected to have an all-round impact on the existing semiconductor industry?

Jiwei.com News: The 15th China Electronic Information Technology Annual Conference was held in Chongqing Liangjiang New District from April 17 to 18. Wide bandgap semiconductors and carbon-based technologies were highlighted at the conference.

Wide Bandgap Semiconductors

Hao Yue, academician of the Chinese Academy of Sciences, vice president of the China Electronics Society, and professor at Xidian University, said that wide bandgap semiconductors have been widely used in the fields of automobiles, health, etc.

Hao Yue also predicted that 6G communications may enter industrialization in 2030, and wide bandgap semiconductors will release huge market potential and strong development momentum in the future.

In addition, Hao Yue said that China has proposed the "3060 carbon emission target", which also gives wide bandgap semiconductors a broader prospect. Of course, we still need to continue to work hard to reduce the consumption in the transmission process while the total amount of electricity increases, and promote the early realization of the carbon peak and carbon neutrality goals.

my country established the National Engineering Research Center for Wide Bandgap Semiconductor Devices and Integrated Circuits in 2020, and has made technological breakthroughs in many fields including gallium nitride semiconductor equipment and gallium nitride millimeter-wave power devices.

Carbon-based technology

Peng Lianmao, academician of the Chinese Academy of Sciences and professor at Peking University, said that as the chip manufacturing process approaches 2 nanometers, the potential of silicon-based chip materials has been basically exhausted and cannot meet the needs of further development of the industry in the future. The use of new materials is recognized as a way to fundamentally solve chip performance problems.

Peng Lianmao pointed out that carbon nanotubes have perfect structures, ultra-thin conductive channels, extremely high carrier mobility and stability, and are expected to replace traditional silicon-based integrated circuit technology in the future. Facing the post-Moore era, China has basically solved the challenges faced by carbon nanotubes and realized a complete set of carbon nanotube integrated circuit and optoelectronic device preparation technologies. At the same time, it has also made major breakthroughs in the research of carbon nanotube doping technology, making my country a global leader in basic research on carbon-based chips.

Peng Lianmao believes that carbon-based technology is expected to have an all-round impact on the existing semiconductor industry landscape
