The gist of what you have been saying over the last few pages with regards to SMEE's 90 nm lithography machines is that they do not produce sufficient commercially viable chips in terms of the number of wafers they process per hour, huh?
If the only "issue" of the SMEE's 90 nm SSX600 series machines would have been slow productivity, I guess, all considered, that they would had sell them
anyhow, at least is small numbers. My take is that there are other problems, impossible to say which. The most immediate and natural assumption is a combination of reliability issues
AND that SMEE seems to have abandoned the project.
If, as it seems, there is still no machines production
after many years from their market launch, then is fair to say it is probably a dead project now, because SMEE is today totally involved in the development of the new SSX800 dual stage series. Who would buy an unsupported and not actively developed machine of which exist only very few and old prototypes?
Unfortunately SMEE is a very secretive company, even for Chinese standards. There are no official statements, no public roadmap, no financial statements, no official revenue and sales information. Even SMEE's size and number of employee is not known officially. There is just their website with many stale pages, and a wild sea of rumors and half-infos.
We can safely assume that they have progressed a lot since years ago, when their website refers, but where are they now? Nobody from SMEE likes to talk.
