SMIC's N+2 process is supposed to have 113.6 million transistors per sq millimeter. This is basically the same as TSMC's N7+ using EUV in critical layers with 113.9 MTr/mm2. Compare that with when TSMC was still only using DUV. DUV only N7 process had 91.2 MTr/mm2.
SMIC's N+2 is slightly better in terms of density than Samsung's 6LPP process which has 112.79 MTr/mm2. It also compares much favorably in terms of density with Intel 7 which only has 100.76 MTr/mm2.

SMIC's N+2 is basically on the 6 nm intermediate node class in terms of transistor density. You could argue that in terms of transistor density SMIC is right now ahead of Intel until the Intel 4 process enters the market.

HiSilicon used the SMIC N+2 process in the Kirin 9000S. But they also used their own core design with two-way SMT. This means each core has higher multi-threaded performance than competing ARM core designs in the same process. This enables the processor to be competitive against 5 nm designs.

Your had made two mistakes:
TSMC 7nm+ basic cell size is 171x240nm
SMIC N+2 is 180x252nm. so your claim that N+2 share the same transistor density with TSMC 7nm+ is incorrect. If you use Apple-to-Apple calculation of assuming 60% NAND cell and 40% SFF cells, N+2 would have transistor density of about 103MTx/mma^2

(and if you use TechInsight's CPP measurement off the Kirin9000s, which is 63nm, instead of 60nm (which is what I used), then N+2 would have cell size of 189x252nm with corresponding transistor density of 98.1 MTx/mm^2).

Intel 10nm density is 100.76MTx/mm^2. The improved and newly named Intel7 has smaller cell size so has density of around 106MTx/mm^2.

there's a few process node breakpoints where process chemistry changes such as poly-Si gate metal to metal gate conductor, oxide gate dielectric to high-k gate dielectric, going from planar to finFET, etc.

High-k was a huge thing when I started when 45 nm was about to get introduced. Then, if I remember correctly, fabs delayed the introduction which made everyone upset because we were having problems with power use at 45 nm.

EUV light using femtosecond lasers, could be used for mask inspections and other EUV tasks.

A key engineering project in Shanxi Province, Haina Semiconductor's silicon monocrystalline project is about to be put into production​

"Taiyuan Daily" reported on November 7 that the construction of the semiconductor silicon monocrystalline production base project of Haina Semiconductor (Shanxi) Co., Ltd. is nearing completion, and it is currently sprinting to put into production with all its strength.
Haina Semiconductor (Shanxi) Co., Ltd.'s semiconductor silicon monocrystalline production base project has a total investment of 546 million yuan, covering an area of approximately 133.85 acres and a construction area of approximately 89,700 square meters. The project uses Haina's own technology to introduce 120 sets of monocrystalline production equipment, build a 6-inch semiconductor silicon monocrystalline production base with an annual output of 750 tons, and carry out research and development of production technologies related to 8-inch to 12-inch semiconductor-grade silicon monocrystalline.
According to public information, Haina Semiconductor’s silicon monocrystalline production base project has been included in the key engineering projects of Shanxi Province.
Zhejiang Haina Semiconductor Co., Ltd. was established in September 2002. Its predecessor was the Zhejiang University Semiconductor Factory established in 1970. In September 2021, the company invested in Shanxi and established Haina Semiconductor (Shanxi) Co., Ltd. In January of the following year, Shanxi Haina Semiconductor's silicon monocrystalline production base project was settled in Yangqu Park. In May 2022, the project will start; in June 2023, the main factory building of the project will be capped.
