2, Therefore,In terms of chip development and design, domestic chips are at the same level as foreign chips. In this regard, we must be fully confident and confident.
3, the difference between STM32 domestic chips and imported chips are mainly the following points: manufacturer: Domestic chips are produced by domestic manufacturers, and imported chips are produced by foreign manufacturers. Technical level: Imported chips are usually more advanced and mature in technology research and development, while domestic chips may be relatively backward in technical level.
4, the first 5G products are not recognized, followed by various limitations in the processor system.The comprehensive performance of Huawei Kirin chip is currently ranked third, and 5G technology is the world's leading, so the purchase of Huawei chips is not worse than other brands. On the other hand, when the car recorder is connected to the Internet, it is a "naked" thing.
5, No. Xiaomi has only one mobile phone using a self-developed chip, on February 28, 2017, the Surging S1 chip was officially released, and the first mobile phone equipped with the Surging S1 chip Xiaomi 5C was also released. The rest of Xiaomi's phones are powered by Qualcomm's Snapdragon series of chips or third-party chips.
There is a big gap between Chinese chips and American chips from chip design, chip equipment, chip manufacturing, sealing and testing. In terms of chip design, the United States has 74 percent of the market share, while China accounts for only 3 percent, and in key technology areas such as EDA software, China relies heavily on design software imported from the United States. From this perspective, the gap between China and the US mobile phone chips is reflected in the restrictions imposed by US sanctions on China's chip industry. Although China's chip manufacturing industry in chip design, manufacturingThere has been great progress in packaging, but its dependence on chip equipment, raw materials, core accessories and other aspects is still very high.
It is easy to be held by others. Although the chip bill signed by Deng has an adverse impact on China's chip industry, from the perspective of interests, the development of China's chip industry will be more independent. One day in the future, a very strong chip will be developed that will not be affected by other countries.
The indirect effect is that the chip Act may initiate a new round of large-scale investment in the entire semiconductor industry in the United States, which will increase global semiconductor supply to some extentThe competition will have an impact on China's existing manufacturers and production capacity.
Recently, US President Joe Biden signed a $280 billion chip bill, at the same time, the US government is also strongly supporting US chip companies, intending to build its own full set of chip industry in the future, reducing demand for overseas markets. The President of the United States signed this bill to compete with our country.
The second is manufacturing, including finished product production and semi-finished product production. Semi-finished products are wafers, and high-purity wafers are basically monopolized by Japan; On the basis of wafers to make chips, TSMC market share is the largest, SMICIt is usually more advanced and mature in terms of technology research and development, while domestic chips may lag relatively behind in terms of technology level.
From the perspective of the process process, the chip process process refers to the manufacturing process of the production of chips, which is one of the important indicators to measure the cost performance and performance of chip manufacturing. At present, the world's most advanced chip manufacturing process is still at 4nm, and China's chip manufacturing industry is at a relative disadvantage in this area.
Don't always stare at the lithography machine, the real gap between domestic core and American core is still in the patent and standard! Many people think that China's chip manufacturing process is not good, and it is trueThe former domestic lithography machine can only reach the accuracy of 90nm, and the process level of SMIC, the best chip foundry in China, is only between 28nm-14nm.
The main gap is that the high-end IC design capability of the chip is not strong The industrial chain of the semiconductor industry is divided into upstream, midstream and downstream three stages, accordingly, the enterprise is roughly divided into design enterprises, IC manufacturing enterprises, packaging and testing enterprises.
In contrast, there is a certain gap in the technical level and performance of domestic chips. Quality and reliability: PRy chip products are more strict in terms of production process and quality control, soThe quality and reliability of its products are high.
