1, the smaller the length unit, the better the reason is higher performance, lower power consumption. Higher performance: As the nanometer size shrinks, the number of transistors continues to increase, making the chip faster and more powerful. Lower power consumption: As the nanometer size decreases, the resistance value of the transistor changesSmaller, less heat is generated as the current passes through, reducing the chip's power consumption.
2, the smaller the chip nm, the higher the integration, the stronger the performance. The chip is essentially an integrated circuit, the smaller the process, the more complex the integrated circuit in the same area, the stronger the performance of the circuit. This benefit is more obvious on mobile phones, because mobile phones in the pursuit of thin and light at the same time to achieve maximum energy efficiency, so the processing chip process is of course the smaller the better.
3, the smaller the gate length, the higher the frequency of the chip or the lower the power consumption. The grid length (or channel length) decreasesWith the distance between the source and the drain, the electrons only need to flow a short distance to run, thereby increasing the switching frequency of the transistor and increasing the operating frequency of the chip; On the other hand, the reduction of gate length and electron flow distance can reduce the internal resistance of the chip, the required opening voltage and the operating voltage. 4, like the current chip manufacturers are in the pursuit of smaller processes, such as TSMC entered the 7nm era last year, and next year may enter the 5nm era, the current Samsung is 8nm, SMIC is 28nm. Seemingly small gap, then like 7nm chip and 10nn chip compared to the gap in the endElectronics, NAURA. Zhayi Innovation ranks among the top three in the global Nor flash market, and its market share continues to increase with the withdrawal of Japanese and American companies; Storage prices are soaring, and the company's profitability is booming. The company builds IDM storage industry chain.
3, the current domestic chip industry leaders are: Huiting Technology 603160 (global fingerprint recognition chip field leader); Zhaoyi Innovation 603986 (China's leading flash memory chip design enterprise); Ziguang Guowei 002049 (the latest financial IC card chip has reached the world's leading level).
4, China's chip industry is rising rapidly, there are some potential domestic chip companies. Semiconductor Manufacturing International Corporation (SMIC), a semiconductor manufacturing company founded in 2000, focuses on providing advanced chip manufacturing processes on 12-inch wafers and is the only chip manufacturer in China with commercial 14nm FinFET technology.
5, the top ten semiconductor chip leading stocks in China are: NAURA; Smic; Zhaoyi innovation; Zhuo Sheng micro; Purple light country micro; Weil Shares; Beijing Junzheng; China Resources Micro; Yang Jie Technology; Changdian Technology. Naura.
1, 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. Neutral lightEngraving 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. At present, the manufacturing process level of China's chip has reached 14 nm, which can meet the needs of most application scenarios. In the future, the manufacturing process of Chinese chips will be further improved, and it is expected that by 2025, the manufacturing process of Chinese chips will reach 7 nanometers.
3, according to recent news, China lithography machine has made a major breakthrough in the chip manufacturing processA higher level of accuracy is achieved. At present, Chinese lithography machines have achieved a level that can produce 7 nanometers of wire width, and have made significant progress in resolution and manufacturability.
4, 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.
5, the Chinese lithography machine now reaches 22 nanometers. Before the breakthrough in microelectronics technology in Shanghai andMegastare, China's domestic lithography machine has been stuck in the production of 90nm process chips. This time, China has directly broken through from 90nm to 22nm, which means that China has achieved localization in some key core areas of lithography.
