1, that in addition to the lithography machine Do not use lithography machine to make chips , Do not use lithography machine to make chips Do we need anything else Do not use lithography machine to make chips ? Must still be needed. No lithographyCan you make chips, such as photoresist, mainly in China's domestic basic chemical scientific research, mainly talent team, that is, basic research, basic science, all of these can be established.
2. At present, our difficulties are as follows. The lithography machine and the related equipment that need to manufacture chips, the process and the process problem, the EDA, the market prospect is the acceptance of the people, whether they are willing to use. Let's talk about lithography machine light, engraving machine is the core equipment for manufacturing chips, he decided to do not use lithography machine to manufacture chips No lithography machine can make chips , which can transfer integrated circuit patterns to silicon wafers.
The five-nanometer chip does not require lithographyThe machine is real. Canon has announced that by using NIL nanoimprint technology to manufacture chips without lithography , it will be able to manufacture 5nm chips without the use of EUV lithography machines by 2025. The NIL nanoimprint technology is similar to printing technology in that the chip is manufactured by burning the circuit pattern onto a dedicated chapter, which is then imprinted onto a silicon wafer.
No EUV lithography machine is required, and nanoimprint technology can achieve 5nm chips. Recent news reports claim that Chinese chipmakers have successfully developed a new technology, known as NIL Nanoimprint technology. This technology is believed to be able to bear the work of EUV lithography machines and has lower production costs. NIL (Nanoimprint Lithography) is a nanoreplication technology that copies the pattern of a chip onto the surface of a silicon wafer.
3, different raw materials, different manufacturing methods. The materials are different. The raw material of the carbon-based chip is the new material graphene, and the raw material of the lithographic machine chip is nonlinear optical crystal material. systemConstruction methods. Lithography chips are chips that need to be processed by lithography machines, and the processing of carbon-based chips can bypass the lithography machine, making it easier to manufacture.
4, the application of lithography technology chip manufacturing: modern lithography machine is an essential tool for manufacturing semiconductor chips, its high resolution, high precision and other characteristics make the chip manufacturing process more refined. LED manufacturing: lithography machine can be used to manufacture high-brightness LED, modern LED lithography machine are using ultraviolet light, making LED manufacturing more accurate, high efficiency.
5. The point is, this carbon-based chip canWithout EUV lithography machine, domestic lithography machine can be used. During the development of this project, gratifying results have been achieved in the preparation of 90 nanomaterials, key processes and device properties, and application exploration, and are all in the world's leading level. This acceptance is a big step closer to commercial use of carbon-based chips. 6, since entering the information age, our domestic level of science and technology has been rapidly improved, in various fields have mastered a certain core technology, and the gap with some developed countries is getting smaller and smaller.
Lithography machine is a very important equipment in the manufacture of integrated circuits, especially now most of the chips on the market are electronic chips, when the process of electronic chips is less than a certain size, you must rely on the lithography machine in the production of chips, that is to say, if there is no lithography machine, there is no way to manufacture the top chip. For example, it is impossible to make 7nm chips and 5nm chips on the market.
Lithography machine and chip close connection Lithography machineAnd the relationship between the chip is extremely close. The development of chips cannot be separated from the high-precision processing of lithography machines, and the relationship between the two is like fish and water, which complement each other. Without lithography, even the most advanced chip design techniques are difficult to achieve. Lithography and chip manufacturing are both extremely difficult, but the technical challenges of lithography are even greater.
Lithography machine is the core equipment for manufacturing chips, and the integration level of chips depends on the accuracy of the lithography machine. This article will delve into the relationship between lithography and chips, as well as the difficulty of lithography and chips. There is a close relationship between the lithography machine and the chipInseparable relationship. The relationship between the chip and the lithography machine is like fish and water. Without the lithography machine, the high-end chip technology can only stay at the ideal level. In fact, I have always believed that chip technology is a comprehensive technology, lithography machine technology is like a "sharp knife", stuck in our hearts, so the chip is life, lithography machine is the guarantee of life. However, on the one hand, because of the constraints of domestic lithography machine technology, for us, no lithography machine is like being alert to the crisis of this chip.
The relationship between the chip and the lithography machine is like fish and water. No lithography, no high-end coreFilm technology can only stay at the ideal level. At present, the world's highest end lithography machine from the Netherlands, I believe that soon China can also have independent lithography machine technology. The lithography or the chip is harder.
