I think its a JV half owned by Beijing government. Beijing government is more sensitive politically and No American tech in whatever they do.Yes thats right. This SMIC plant in Beijing is for the localised 28nm Production Line.
It will use the SMEE 28nm DUVL and have all localy made Semiconductor Equipment.
It is an important project which will give China greater independence in Semiconductor production.
Whereas SMIC, with alot of taiwanese engineer influence prefer to work with more established western or US equipments .
