In the past, China's lithography machine can only reach 50 nm production accuracy, however, in recent years, seize the opportunity, vigorously develop technology, China's lithography machine successfully achieved 25 nm and 18 nm production accuracy, successfully pushed the industrial chain to a higher level.
The Chinese lithography machine now reaches 22 nanometers. Before the breakthrough in microelectronics technology in Shanghai, China's domestic lithography machines have been stuck in the manufacture of chips with a 90nm process. This time, China has directly broken through from 90nm to 22nm, which means that China has achieved domestic production in some key core areas of lithography machineryMelt.
nano. According to the Chinese People's Daily Online, China has successfully developed the first domestic 28-nanometer (nm) lithography machine in 2023, which is expected to be delivered by the end of the year.
smee lithography machine 22 nm. lithography, also known as mask alignment and exposure machine, exposure system, lithography system, etc., is the core equipment for manufacturing chips. It uses a technique similar to photo printing to print fine graphics on a mask plate onto a silicon chip through light exposure.
1, 14 nm. According to the latest data, as of 2023, China has been able to produce 14-nanometer chips in the field of chip manufacturing, and the mass production rate has reached a high level. Chips are key components in electronic devices, which use microelectronics technology to integrate complex circuits and systems on tiny silicon wafers.
2, China's domestic chips can now reach the process level of 90 nm. In the key links of chip manufacturing, equipment and materials such as lithography machine, etching machine, wafer, photoresist occupy an important proportion. Especially the lithography machineAt present, Shanghai microelectronics enterprises have been able to provide 90 nanometer products.
3. Huawei is currently capable of producing 3-nanometer chips. Huawei's chip manufacturing technology has reached the level of several nanometers, and is developing chips with 2 nanometers. Huawei has strong competitiveness in areas such as mobile devices, cloud computing and artificial intelligence, thanks to its advanced technology and manufacturing capabilities in chip manufacturing.
4, domestic chip level can only achieve 90 nm. From the perspective of chip manufacturing, equipment and materials such as lithography machines, etchers, wafers, and photoresist account for a large proportion. Medium lithographyMachine equipment, the current Shanghai microelectronics is 90 nm. High-end KrF and ArF photoresist are almost dependent on imports, of which ArF photoresist is almost zero domestic.
5, nanometer. According to Baidu Encyclopedia information shows that China can produce 14-nanometer chips by September 25, 2023, with a mass production rate of 95 percent. A chip is an electronic component, manufactured by microelectronics technology, that integrates circuits and systems on a tiny piece of silicon.
6, China's chip manufacturing process level At present, China's chip manufacturing process level has reached 14 nm, which90 nanometers, wavelength 193 nanometers. The most advanced model of domestic lithography machine is SSA60020 from Shanghai Microelectronics.
3, nano. According to the Chinese People's Daily Online, China has successfully developed the first domestic 28-nanometer (nm) lithography machine in 2023, which is expected to be delivered by the end of the year.
4, the domestic lithography machine broke through the blockade and successfully developed 22nm lithography machine, and China core is gradually rising.
5, in the past, China's lithography machine can only reach 50 nanometers of production accuracy, but in recent years, seize the opportunity, vigorously developTechnology, China lithography machine successfully achieved 25 nm and 18 nm production accuracy, successfully pushed the industry chain to a higher level.
6, package lithography machine has occupied a large share in the domestic market, which is the progress of domestic lithography machine.
