1, nanometer. According to the search Baidu encyclopedia information shows that China's cut-off 202On September 25, 2013, 14-nanometer chips can be produced 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.
2, at present, the most advanced process chip that can be mass-produced in the mainland is 14nm. In the fourth quarter of 2019, SMIC said that 14nm had been put into mass production. In 2021, the news came out that SMIC's 14nm yield reached 95%, which has been tied with TSMC (7nm has also been put into small production).
3, China's chip manufacturing technology can nowZhuhai Action Force, Shanghai Jingchen, Shanghai Infang Micro. At present, China's IC chip design companies are not as well known as Intel, Qualcomm, Apple, and Samsung.
2. As one of the leading mobile phone chip suppliers in China, Spreadtrum Communications (Shanghai) Co., Ltd. has been committed to independent innovation, and has formed 2G/25G/3G/35G mobile communication technology baseband and RF chip product series. Completed TD-SCDMA, TD-LTE core chip research and development and industrialization and other national key research topics.
3. It is currently fully controlled by ZTE.Its main products include multimedia chips, communication base stations and chips for wired products. In the field of wireless products, the 7nm core chip of ZTE Microelectronics 5G has been commercialized, and the high-performance and full range of wireless products based on the 7nm self-developed chip help operators to build a cost-effective and smooth evolution of 5G networks.
4, so people will start to wonder whether China now has its own chip? This is there, but the performance of the international or the gap is relatively large, this is for the cpu of the computer.
5, soul core series, dragon core series, Via series, Shenwei series, Feiteng systemColumn, Shenwei series; Embedded chips are: Starlight series, Beidazhi series, Hunan SMIC series, Wantong series, Ark series, Shenzhou Loongson series. 6, their own research on a mobile phone chip, it is not impossible, because if you just rush to research out, then this is relatively simple, it should be said that now the four major manufacturers of the four mahjong, Southeast and northwest which have this strength.
China's major chip companies are: Huawei hisilicon, Tsinghua Unigroup, ChinaCore International, Haowei Technology, Zhonghuan Semiconductor, ZTE Microelectronics, CLP Huada, Changdian Technology, Nastar, Nanrui intelligent core, etc. Tips: The above content is for reference only, ranked in no particular order.

China's top ten semiconductor companies are: Weil shares, Unigroup Zhanrui, Yangtze River Storage, ZTE Micro, Hisilicon, Zhaoyi Innovation, Mu Linsen, Geke Micro, Shilanwei, Goer shares.
Domestic chip brands are ZTE, Hisilicon, Sunway, Feiteng, SMIC.
2, since Huawei's chip production capacity has been limited, chip localization replacement has become the main theme of China's semiconductor development. Since July 2020, the state officially invested 160 billion yuan in the construction of the Oriental Core Port project in Shanghai, China halfA surname. After converting all the products into 200mm wafers.
The status quo of the chip technology development is as follows: At present, there are still many problems and challenges in the status quo of China's chips. Chip design, process, equipment and other aspects of the technical level is relatively backward, while the lack of some key chip areas of independent intellectual property rights. On June 9, at the World Semiconductor Conference, Wu Hanming, academician of the Chinese Academy of Engineering, pointed out the status quo of China's chips: China wants to complete the localization of chips and replace them, and there is still a shortage of 8 core international.The field of packaging has achieved independent research and development, and has made remarkable progress.
The status quo of China's chip manufacturing level is as follows: China's chip industry started late, and its core technology is subject to others. The integrated circuit industry has a big gap compared with the world advanced level in core technology, design, manufacturing process, industrial scale, leading enterprises and so on. Broadly speaking. In addition, the Chinese government has also introduced a series of policies to encourage domestic enterprises to improve their independent innovation capabilities and increase investment in chip research and development. However, China's chip industry still faces some challenges. On the one hand, China's chip manufacturing technology and level with the countryThere is still a gap between the international leading level, especially in the field of high-end chips.
Domestic chip brands haveZte, Hisilicon, Sunway, Feiteng, SMIC and so on.
SMIC is the largest wafer foundry in China, which basically represents the cutting-edge technology of domestic chips.
