BA, what part of "doesn't contain any software" didn't you understand?
Also, your statement that "the companies that specialise in semiconductor manufacturing equipment and a lot of the process control software used in the fabs are American".is actually not correct either. Taiwan Semi Conductor might take issue with your statement.
As to "worldwide companies", the US administration can make noise all day long, but the rest of the world carries on
But more to the point, the OI presently uses NOTHING in it's epitaxial stack that is American.
