@olalavn again sorry for being a nuisance, Do you mean verify in SMIC Chengdu FAB?
The official Great Wall of China announced that the company's Zhengzhou Railway Transport Information Technology Research Institute, based on the experience and development base of semiconductor laser invisible wafer cutting equipment, introduced a new technology that fully supports cutting ultra-thin wafers. Fully automatic 12 inch laser grooving equipment .
in addition to conventional laser grooving, it also supports 5nm DBG process, ultra-thin wafer full cutting function below 120 microns, IGBT fab-related processes and TAIKO ultra-thin ring cutting and other Other high-precision processes finish the process.
The Great Wall of China official claims that the device's modular design can support lasers of different pulse widths (nanosecond, picosecond, femtosecond). The self-developed optical system can continuously adjust the width and length of the spot. With high-precision motion control platform and other technologies, it is combined with laser stealth cutting equipment to solve the problems of laser stealth cutting equipment on surface materials, thickness , crystal orientation and resistivity. Limit, which helps control product breakage rate and improves chip yield.

there are rumors...it's Huawei's factory
SMIC did make this announcement of N+1/N+2 was in 2020. Many not familiar with the industry do not fully understand what N+1 & N+2 means so have many different interpretations. And there's lot of speculations on SMIC's actual progress.
Those close to the Chinese semi industry are not too surprised about this TechInsight report. At least those I talked to this morning, no one was surprised. It's no secret in the circle that SMIC had shipped bitcoin chips to their customer last year. So, what I mean is many people are aware of this so is no secret.
There's a lot of speculations and doubts by the westerners on the validity of SMIC's claim from 2020. The most significant one, I think, is most think SMIC could not ship actual N+1/N+2 wafers to customers. So having an actual SMIC chip will rule out those western naysayer.
Having read the little excerpt from TechInsight, they are also in agreement with what I said that the "7nm" chip they analyzed are N+1 chips. And that these chips is a precursor or a learning step to get to true 7nm or N+2. But since other articles that are hyping TechInsight's analsyis are all calling this chip 7nm or N+2, I'm sure the hawks will jump on this twisted "truth" to push their agenda along. The part about 'smoking gun' and the 'hawks' is my guess. Maybe the hawks had been aware of this or maybe they are learning about this for the first time....I'm assuming they know about it but have no solid proof in making my speculation.
Hope this clarifies what I was trying to convey.

Thanks for sharing. I'll have to use Google translator after work to study what this says.
it's just a network component factory
@hvpc Yes bro, I'm so happy right now and thanks to you both for making it happen.
And thanks to @Oldschool also, there are doubts as @gelgoog had pointed out that SMIC doesn't operate a FAB in Chengdu, so this info from @olalavn clarify it, maybe a JV between SMIC and Huawei?
