At present, SMIC's advanced process chips have developed to 7 nm, and there are relevant rumors that 7 nm is currently in risk trial production, but whether it is really in trial production is still uncertain, because SMIC has not yet expressed its position on 7 nm.

However, there is a good news at present, that Huawei Hisilicon 28 nanometer process has achieved mass production, and this chip is manufactured by SMIC, but you should know that it has entered the era of advanced process chips, 5 nm and 7 nm are not the most advanced.
But now it is still only able to produce 28 nanometer chip industry, it is indeed a little embarrassing, but to know that 28 nanometer is just needed in the country, in the field of autonomous driving communication and new energy vehicles, the demand for 28 nanometer is very high. Although in technology, we are still behind, but in the 28 nm, we have already completed the autonomy.

Earlier, Hu Weiwu of Longson Zhongke once said that we do not need to catch up with the advanced pace of the United States, only need to expand production on the mature process.
Smic has twice expanded in the 28 nanometer process, in addition to SMIC, including TSMC and so on, many companies have been in the 28 nanometer node capacity on a large scale expansion, and the reason why these contract manufacturers will expand 28 nanometer, is because the 28 nanometer application range is relatively wide, and the cost performance is relatively high

According to the relevant data, after 2017, the application of 28 nm in many fields such as smart home appliances, the Internet of things, and automobiles has begun to increase rapidly. TSMC's 28 nm node accounted for about 25% of sales in 2015, and it still remains above 10%.

At present, the most shortage of display driver chips in China, automotive electronic chips, etc., are also 28-nanometer process, and from the cost point of view, the 28-nanometer process is relatively mature, and the cost performance is relatively high for the OEM, so it is not difficult to see that the 28-nanometer node will become the main process node of the major OEM expansion. So stop saying Hisilicon's 28nm line isn't working
