Huawei released its latest flagship mobile phone Huawei Mate 60 Pro earlier, according to TechInsights on Huawei Mate 60 Proanalyze，Huawei Mate 60 Pro Equipped with the 5G mobile processor “Kirin 9000s” designed by Huawei’s Hisilicon Semiconductor and manufactured using an N+2 process close to TSMC’s 7nm process, it made the world reflect on the US ban on Huawei. Being in trouble, it also made its research and development technology more breakthrough.

Kirin 9000s is manufactured by SMIC’s N+2 process, and its energy efficiency is close to 7 nanometers
It is rumored that the processor of the Huawei Mate 60 Pro is a 7-nanometer (N+2) process manufactured by China’s SMIC, which can be said to be a breakthrough in China’s chip manufacturing technology. Because it was generally believed that SMIC currently only has the ability to produce 14-nanometer process chips at most (although the mining machine was dug out before and is also a 7-nanometer process), but this time SMIC still produced chips under the blockade of US sanctions. The Mate 60 Pro’s N+2 process chip has surprised people from all over the world.
According to the research of the TechInsights team, the chip area of the Kirin 9000s produced by SIMC is 107 square millimeters, which is 2% larger than that of the Kirin 9000.

The chip of Kirin 9000s is more advanced than SMIC’s 14nm industry, but in terms of CDs (critical dimensions), it is larger than the currently observed 5nm process. And other key dimensions include logic gate pitch (logic gate pitch), fin pitch (measurement of fin transistor density pitch), lower back-end-of-line (BEOL) metallization pitches (back-end metallization pitch), TechInsights The analysis team believes that the chip of the Kirin 9000s has 7nm features.
Huawei specially launched the Mate 60 Pro with the 7nm (N+2) process Kirin 9000s processor produced by SMIC when the hawkish US Secretary of Commerce Raymondo visited China, which is quite swearing (ㄉㄚˇ) ㄌㄧ ㄢˇ) means that even if China cannot use more advanced lithography machines due to the ban, it can still make chips with advanced processes. To be honest, under such heavy blockade and sanctions by the United States, it is indeed surprising that Huawei and SMIC can deliver such results. However, if the US ban is not lifted, no matter how powerful Huawei and SMIC are; the energy efficiency ratio will also be difficult to improve. After all, the physical limit of DUV is like this. What needs to be observed is whether the United States will increase the scope of sanctions against Huawei because of its big actions. It is worth follow-up observation.
Huawei’s latest flagship Mate 60 Pro is suddenly on sale, and it is indeed a 5G mobile phone in China
