In recent days, the US government has continued to ferment the ban on Huawei. It has already blown up the circle of friends, causing widespread concern from major media at home and abroad. It is precisely this kind of ban, which has led to more and more Chinese technology companies in the second line. Behind the scenes, the company mentioned in this article is full of black technology. What can it do for the development of China's chip industry? Let us first review the Huawei incident.
At 9:00 on the 21st, Huawei founder and CEO Ren Zhengfei held a round table of Chinese media at Huawei headquarters. He was interviewed by major domestic media for the first time and responded positively to the current difficulties faced by Huawei.
Ren Zhengfei said in an interview that Huawei's 5G technology will never be affected. The current practice of US politicians underestimates our strength, and Huawei is ready.
On the 20th, Qualcomm, Intel also joined Google's camp, and began to freeze Huawei.
Just this morning (23rd), the BBC reported that ARM, the British chip design company owned by Sun Zhengyi, has told employees that they must suspend all business dealings with Huawei and its chip company Hess.
Due to the continued pressure from the US government, Huawei's situation has become increasingly difficult.
This morning (23rd), the BBC reported that ARM, the British chip design company owned by Sun Zhengyi, has told employees that they must suspend all business dealings with Huawei and its chip company Hess.
There is no doubt that Huawei is an excellent world-class technology company and is the pride of China!
However, it is undeniable that China's technology, especially the mobile phone industry, that we are proud of is extremely dependent on foreign technology.
The reason why the United States can block Chinese companies is that Chinese companies, especially giants like Huawei ZTE, rely heavily on US chip companies.
The so-called chip, which refers to integrated circuits, is referred to as "the food of modern industry" and is the cornerstone of the next-generation information industry such as the Internet of Things, big data, and cloud computing.
According to the data of the General Administration of Customs, the three largest industrial products imported by China in 2017 are: integrated circuits, automobiles, and liquid crystal display panels. Among them, the import value of integrated circuits in 2017 reached 1.76 trillion yuan, and has exceeded crude oil for three consecutive years since 2015, ranking first among all imported products.
These three types of medium and high-grade industrial products are not only the shortcomings of China's current manufacturing, but also the main direction of future industrial upgrading. The integrated circuit is the core of the industrial upgrading roadmap because of its highest technical content.
China is a big manufacturing country, but in high-tech fields such as chips, its technical strength and market share are far from the international rivals. It can only work in the low-end chip market.
In the US "blocking Huawei" incident, Ren Zhengfei was so calm and emboldened that it was because Huawei had a long-term layout in the chip field. The HiSilicon chip is an important part of Huawei's chip layout, because the US blockade can be "one night." Turn positive."
The core technology of chip manufacturing is lithography. In the projection exposure system, the mask pattern is imaged on the photosensitive layer of the silicon wafer through an optical system. In this technical process, there is a vital component, which is a reticle. It is a glass plate with a circuit design inside. The current good reticle on the market is hundreds of thousands of dollars.

The design and manufacture of high-precision photomasks has always been one of the technical difficulties in chip manufacturing, and its role is to convert images in a computer into images on a reticle. Due to the high integration of integrated circuit boards, higher requirements are placed on the accuracy of the reticle, so the reticle is crucial to the development of the integrated circuit industry.

Just recently, the national key R&D project “Micro-nano Structure Additive Manufacturing Process and Equipment” achieved major technological breakthroughs: successfully developed sub-pixel micro-scanning technology, which can improve the accuracy of ordinary 3D printing millimeter level to 1μm. the following. The technology can also be applied to the fabrication of high-precision integrated circuit reticle, and the output speed of the technology can reach dozens of times that of similar foreign equipment.

The national key R&D project “Micro-Nano Structure Additive Manufacturing Process and Equipment” was established by the Ministry of Science and Technology of the State Council, led by Prismlab, Southeast University, Nanjing University, Nanjing University of Aeronautics and Astronautics, East China University of Science and Technology, Huazhong Technology University, University of Science and Technology of China, Changchun University of Science and Technology, Suzhou Saifei Group Co., Ltd. jointly research and development.
Micro-Nano 3D printing technology is an important technology for photomask design and manufacturing. It is also one of the important technologies for chip manufacturing. The breakthrough of this technology will have a positive impact on the development of China's future chip industry, in order to speed up the research and development of China's chip companies. Overtaking the mainstream American chip companies has a promoting effect, so that we are no longer subject to people.
Prismlab is the world's leading provider of stereolithography (SLA) 3D printing solutions. It has been concentrating on the development of 3D printing technology, with excellent products, excellent service and fast R&D responsiveness. Into the segment, provide and create a variety of 3D printing solutions that have a profound impact on future manufacturing, and have been recognized by well-known corporate customers in various industries.
