China promotes the development of new silicon photonic technology, without EUV lithography machine and advanced technology!
The chip war between China and the United States is in full swing, and American think tanks have found a loophole! We lost to China's chips!
The Center for Strategic and International Studies (CSIS), a well-known American think tank, recently wrote that in the next decade, silicon-based photonic technology will be a new battlefield in the Sino-US science and technology battle, or will rewrite the future of the semiconductor and artificial intelligence industry.
UV lithography is not required. Advantages of photonic chips.
With the increasing demand for high-end chips around the world, the traditional chip process is at the end of its rope. It is becoming more and more difficult to manufacture artificial wafers.
In this context, optoelectronic chips have become an emerging technology and are considered to be the key to determining the future information technology revolution.
A photonic chip, as its name suggests, is a photonics-based microchip. It is a photon-based (optical particle) information transmission and processing technology, which has many advantages over traditional electronic devices.
First, photonic chips are delivered much faster. Photonic chips transmit data at the speed of light, nearly 300,000 times faster than electrons. This means that photonic chips can transmit a lot of data at high speeds, making communication and computing more efficient.
Secondly, the power consumption of photonic chips is smaller. Compared to conventional electronic devices, photonic wafers have very little energy loss. This is due to the fact that photonic wafers take advantage of the transmission properties of light waves, so that photons rarely interfere with each other, thus reducing energy loss.
In addition, photonic chips have a higher level of integration and a smaller size. In photonics chips, multiple optical components such as light sources, optical modulators, and light detectors are integrated into a single chip, which greatly reduces the volume and mass of the system. The research results of this project will provide new ideas for the application of photonic chips in communication, computing, and sensing.
China's biggest advantage is that it does not use ultraviolet lithography technology in the production of its optical wafers, which has been banned by the West.
China's optoelectronics core technology has achieved a major breakthrough.
China has a long history in optoelectronic technology. China"14th Five-Year Plan"and"Vision 2035"Photonics technology as a way to circumvent Western technology control.
China Xintong will also build an optoelectronic chip production line, marking China's leading position in optoelectronic technology and will bring revolutionary changes.
China has established the world's first optical and quantum chip production line, which is not only China's efforts in these two aspects, but also a manifestation of China's leading position in these two fields.
Something. 
There are undoubtedly still certain problems in the development of photonics in China.
First, photonic chips are expensive to manufacture, so a cheaper and more efficient process must be developed.
Secondly, this project will also study the stability and reliability of optical chips to provide a reliable guarantee for their practical application. In addition, at present, the standardization and industrialization of optoelectronic technology in China is still in the initial stage, and it is urgent to strengthen exchanges and cooperation with domestic and foreign countries.
