3, China's top ten chip enterprises are: Unigroup Group, Huawei hisilicon, Changdian Technology, SMIC, Taiji Industrial, Zhonghuan Stock, Zhenhua Technology, Nasstar, ZTE Micro Electronics, Huatian Technology. Among them, the more advanced are Unigroup Group and Huawei hisilicon. At present, Unigroup and Huawei Hisilicon are already the world's leading companies in many fields, but a huge problem is the core of their architecture authorization
Chinese memory chip three Intel founded in 1968 Headquarters: Santa Clara, California, United States Intel is a personal computer parts and CPU manufacturer founded in 1968, with a 50-year history of market leadership, introduced the first microprocessor in 1971, brought the computer and Internet revolution to the world.
At present, China is at a disadvantage in the three major fields of chips: logic chips, memory chips and analog chips. In all three areas, US companies are unquestionably dominant. China wants to achieve self-sufficiency in chipsHere, it is inevitable to break through the technological blockade and patent wall of the United States, and a dragon fight is inevitable. However, in the short term, China's chip industry chain is under great pressure.The three chip manufacturing giants are: Intel Founded: 1968 Headquarters: Intel is a personal computer parts and CPU manufacturer founded in 1968 with a 50-year history of market leadership that revolutionized the world of computing and the Internet with the introduction of the first microprocessor in 1971.
These are the Tier 1 giants of the fuel car era, facing electrificationWave collective dumb fire, the reasons given for layoffs are not the same, but there is always a problem that can not be avoided - electric transformation. With software, chips, and three-power systems as the core of the new three major components, so that the advantages of traditional supply chain giants are no longer, in order to continue to maintain a leading position, it is necessary to take the initiative to change, layoffs may be the first knife.

GOODIX is a brand owned by Shenzhen Huiting Technology Co., LTD. Founded in 2002, Goodix is the world leader in human-computer interaction and biometrics technology, mainly used in mobile phones, tablets and wearable devicesProducts and other fields have a strong strength to launch the press fingerprint identification chip, the fingerprint identification chip of the glass cover plate and other fingerprint identification technology.
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, at the high endIn the field of KrF and ArF photoresist, the self-sufficiency rate of domestic products is almost zero, and it is heavily dependent on imports.
According to the current data show that China's chips can only reach 14 nanometers, but the United States can reach five nanometers in chip manufacturing, this quantitative advantage means that their development is more robust, but even so the United States does not want to let go of China, and even in some application and development has been restricting China. It can be seen that the gap between Chinese chips and foreign chips is far.
Domestic chip level can only achieve 90 nm. From the point of view of chip manufacturing, the lithography machineEquipment and materials such as etching machines, wafers, photoresist account for a large proportion. Among the lithographic machine 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. Therefore, China wants to produce highly localized chips, and at present 90 nm is a demarcation point.
