28nm mobile phone chip technology has been relatively backward.
The reason is that the mainstream smartphone chips on the market now have adopted the process of 10 nm or lower nanometer level, these chips are more excellent in power consumption, performance and battery life, and 28 nm chips have been difficult to meet people's demand for high performance and low power consumption of smartphones. It is worth noting that although 28nm chips have lagged behind, there is still some room for development compared to some low-end mobile phone markets.
Content extension: With the rapid development of 5G technology, the requirements for mobile phone chips are becoming higher and higher.
At present, 7nm chips have become the mainstream in the field of mobile phone chips, and lower nm chip technology is also being continuously developed.
In the future, the performance of mobile phone chips will be stronger, lower power consumption, and longer battery life.
The 28-nanometer chip is not only the United States, but also the mid-end process level everywhere. At present, the only high-end euv lithography machine can only be produced by the Netherlands Asmer, and the largest users of euv lithography machines are TSMC, Samsung, and a small number of Intel. That is to say, only these three can make high-end chips, and Intel is a computer chip, and the technology is not as demanding as TSMC and Samsung. In addition, the chip is basically more than 22 nm, 22-55 nm belongs to the mid-end chip, so 28 nm belongs to the mid-end chip
The 28nm chip technology is the leading level of a decade ago, he said, \"A7 chip is the 28nm process, carried on the iPhone5s,\" now using 28nm is equivalent to using the mobile phone before 2013.

This month, as the mainland's major chipmaker, SMIC opened in Shanghai's science and Technology board jumped 246%, the market value of more than 600 billion yuan. But the latest development of 28nm chip production news has surprised the industry.

At present, the major international chip contract manufacturers can achieve the production level of large-scale mass production of 5nm and 7nm processes, and 3nm products are expected to be put into production next year.
