1. Electron beam lithography. Chips smaller than 5nm can be made using electron beam lithography.With a quantum chip. Quantum chips can be made smaller than 5nm and do not use a lithography machine.
2, no euv lithography machine, also can not make 3nm, domestic chips can use advanced packaging technology to improve chip performance and reduce costs. The absence of EUV lithography machines does not mean that Chinese chip companies cannot achieve 3nm processes.
3, Yes, the production of chip lithography machine is the most important, needless to say, the West is also blocked for our country, the lithography machine can not be bought. Do we need anything else besides a lithography machine? It must be neededFor example, photoresist, mainly in China's domestic basic chemical scientific research, mainly in the talent team, that is, basic research, basic science, all these can be established.
4, Top-Down: top-down method silicon-based chip manufacturing is the use of top-down micro and nano finishing technology, the use of equipment is ASML lithography machine. The lithography machine is like a carving knife, and the components of the chip design paper are carved into the silicon wafer with light. The manufacturing of carbon-based chips takes advantage of this Bottom-up micronagarIt's like building a house.
5, the steps of chip manufacturing, it is easier to understand the difficulty of chip manufacturing. The wafer is extracted, the extracted monocrystalline silicon is made into silicon ingots, and then cut into several wafers, which is what becomes a wafer; The application of photoresist on the wafer is a constraint to our development.
1, people are constantly looking for new materials to break through the bottleneck encountered by carbon-based chips, the most advancedCarbon nanotubes make ideal transistor materials, and carbon-based chips based on carbon nanotubes do not require a lithography machine.
2, Yes. Photoresist is an important material for the research and development of lithography machines, and is the key material for the fine graphics processing in microelectronics technology. The lithography machine uses special light to map integrated circuits to the surface of silicon wafers. If you want to leave traces on the surface of silicon wafers, you need to apply photoresist on its surface. Photoresist corrosion resistance, surface tension have very high requirements, photoresist tape is not only used in chips and high-end panels, LED and so on.
3, from the technical level, the current Chinese nativeThere is a significant gap between the overall technical level of photoresist and the international advanced level, and it is mainly concentrated in the field of PCB photoresist with low technical content, and the self-sufficiency rate is low in semiconductor photoresist and LCD photoresist.
4, in addition to Nanda Optoelectronics, Jingrui shares also came to the news that its KrF optical communication has entered the customer test stage. It should be known that Jingrui shares once spent a huge amount of money to acquire Asbuy's lithography equipment from sk Hynix for $11.05 million. This optical technology can develop photoresist up to 28 nanometers. ARF photoresist and ARfi for Jinrui sharesPhotoresist has a certain pushing effect.
5, and the lithography machine is the core equipment for manufacturing chips. Through a series of light source energy and shape control means, the light beam is transmitted through the mask drawing the circuit diagram, and various optical errors are compensated by the objective lens, and the circuit diagram is scaled down and mapped to the silicon chip. Manufacturing process: The manufacturing process of photoresist is mainly a method of chemical synthesis, which requires a series of chemical reactions to get the required materials.
6, lithography machine is one of the core equipment for manufacturing chips. The role is to project light through the optical system onto the wafer surface to form a specific pattern. Have manufacturedThe process of...
2, the methods of producing 5nm chips without lithography mechanism include the use of nanoimprint equipment, the use of SMIC's N1st generation process, the use of carbon nanotubes instead of silicon nanotubes, the use of electron beam lithography technology, and the use of quantum chips. Nano imprinting equipment is used. Using nanoimprint equipment to transfer the microstructure of integrated circuits onto silicon wafers, 5nm chips are manufactured. Smic's N1 process is used.
3, in the semiconductor device production workshop, due to the adsorption of dust on the chip, the yield of ics, especially very large scale integrated circuits (VLSI), will be greatly reduced. IC production workshop operators wear clean work clothes, if the human body with static electricity, it is easy to absorb dust, dirt, etc. If these dust, dirt is taken to the operation site, it will affect product quality, deteriorate product performance, and greatly reduce the Ic yield.
The five-nanometer chip does not need a lithography machine is true. Canon has announced that through NIL nanoimprint technology, it will be able to manufacture 5nm chips without the use of EUV lithography machines by 2025. NIL nanoImprinting 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.
The statement that the five-nanometer chip does not need a lithography machine is not entirely accurate. Although lithography machines play a vital role in the manufacture of microelectronic devices, the manufacturing process of five-nanometer chips still requires the use of lithography machines or other similar devices. Lithography is one of the key tools for manufacturing microelectronic devices, which can transfer integrated circuit patterns to silicon wafers.
The EUV lithography machine is not required, and the nanoimprint technology can achieve 5nmThe chip. Recent news reports claim that a Chinese chipmaker has successfully developed a new technology called 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.
nm chip without lithography machine! Chinese technology companies have applied for manufacturing patents. On September 15, a patent for "direct etching method for 5-nanometer chip manufacturing" applied by a Chinese technology company was officially published. The invention relates to chip design and manufacture. The highlight of this invention is that without EUV lithography or DUV lithography, 5-nanometer chips can be fabricated by direct etching without the lithography process. Once the patent was published, it attracted the attention of a large number of netizens.

2, NIL lithography machine compared to EUV lithography machine, the cost of light source is lower, there is no need to use expensive EUV laser source. At the same time, the NIL lithography machine uses some DUV or more mature light source combined with nanocoating methods, which can achieve one to two nanometersThe mass production of the process has high process accuracy and production efficiency.
3, although the breakthrough in the N 1 process, power consumption is close to 7nm, but the performance is not yet able to reach the 7nm level, let alone 5nm. TSMC and SMIC are restricted by American technology, high-end lithography machines can only be provided by ASML, so when the 7nm process is opened, it may also be the beginning of the commercial use of 3nm process, and Huawei's Kirin chip may have to delay the release. While domestic chip manufacturing is catching up with the international pace, it is also exploring new breakthroughs.
