Unfortunately this article sounds like a Load of Bull, especially the part where it will take SMIC 3 yrs to produce 28nm Chips on a localised production line.Apparently, the US semiconductor bans on Chinese companies have started to rally the Chinese industry behind the drive to be self-sufficiency and indigenous.
(A Japanese owned newspaper quoting a Taiwanese "Expert" is the biggest Joke)
As far as i know SMIC is already building a 28nm Localised production line in Beijing. China's Semiconductor Equipment manufacturers have already developed 28nm Equipment. They are currently working on 14nm Equipment and will start soon on 7nm equipment. Huawei will build their own 28nm FAB early next year.
I made a mistake recently with describing the new SMEE Equipment. SMEE is currently mass producing 2 types of new equipment.
First is a 65nm node Dry Lithograph.
Second is a 45nm node Immersion Lithograph. The 45nm Immersion Litho can produce 14nm, 22nm and 28nm Chips with Multi Patterning.
So SMEE can actually provide a Lithograph now, to local FABs with the ability to make 14nm Chips. The only thing holding the FABs back is the Localised 14nm Equipment which is still under development.
SMIC has been producing 28nm Chips for at least 5yrs years before moving on to 14nm. They have a lot of experience. SMIC can also use reconditioned Manufacturing equipment for 28nm if it is really necessary, where parts are provided locally.
So the whole idea that it will take 3 years to make 28nm Chips sounds extremely unlikely and false.
Also circumstances have changed, with the Government giving more funding and support for Chip making, you can expect many things to happen much quicker.
