China's domestic chips are currently able to 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. In particular, lithography equipment, at present, Shanghai microelectronics enterprises have been able to provide 90 nm level products. However, in the high-end KrF and ArF photoresist field, the stateThe self-sufficiency rate of domestic products is almost zero, and it is heavily dependent on imports.
Loongson 3 processor adopts 65nm (nanometer) process, the main frequency is 1GHz, the number of transistors is 2.5 billion, the maximum power consumption of a single Loongson 3A is 15W, the theoretical peak is 16Gflops, and the single-watt energy efficiency ratio of each CPU is 06Gflops/W, which is more than 2 times of the current X86 CPU. It has reached the world's advanced level. Loongson 3 multi-core CPU series products target servers and high-performance computer applications.
China's chip manufacturing process has reached the 14nm level. acrossIn the past few years, China's chip industry has actively promoted technological development relying on existing conditions. Chinese companies have successfully achieved the mass production of 14nm chips and are working to advance the mass production of 7nm processes. Chip packaging technology can integrate chips of different processes together to improve performance, close to the 4 nanometer level.
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 integrate complex circuits and systems through microelectronics technologySource framework Tensorflow, Caffe, etc., are widely used in medical, security, intelligent manufacturing and other fields.
The number one chip in China is Hisilicon. First place goes to Hayes. Hisilicon, which evolved from Huawei's Integrated Circuit Design Center, is Huawei's main chip research and development center. At present, many of Huawei's mobile phones and tablet chips are equipped with its Kirin chip, and Huawei's current notebook computers have begun to use their own cpus. Of course, Hisilicon also has Balon chips, Centeng chips, and Kunpeng chips.

WeIL is a chip design company for digital imaging solutions, and the company's core technologies such as PureCel, PureCelPlus, RGB-Ir can provide high quality mobile phonesHow many nanometers Max. '> How many nanometers Max. China
1, nanometer. Nanotechnology is the science and technology of manufacturing substances with single atoms and molecules, and China's technology is 28 nanometers, studying the properties and applications of materials with structural dimensions in the range of 1 to 100 nanometers. Nano science and technology is a science and technology based on many modern advanced science and technology.
2, at present, China's most advanced lithography machine can reach a resolution of 22 nanometers. This means that through this lithography machine, extremely fine circuit patterns can be carved on the silicon chip, so as to create high-performance chips. 22nanoMi's technology nodes are critical for many high-end applications, meeting the demanding requirements for chip performance and power consumption in smart phones, high-performance computing, artificial intelligence, and more.
3. China's chip manufacturing technology is currently capable of reaching the 14nm level. In the face of the challenges of domestic chip development, in addition to the challenges of the external environment and the continued sanctions of the United States, which limit access to key technologies and industries, China's chip industry is also trying to enhance its own capabilities through labor-intensive methods. Although progress has been made, there is still a big gap compared with the international advanced level.
4, nanometer. On the basis ofChina People's Daily Online shows that in 2023, China has successfully developed the first domestic 28 nanometer (nm) lithography machine, which is expected to be delivered by the end of the year.
