Old fab lines are being shut down because they can't do the latest small feature processes.
This makes me wonder how the old parts are made. The main one that comes to mind is the 4000
line of CMOS. Others are the really old bipolar processes such as the uA741 and the like.
So, how and where are these dusty old parts made. Did the semi companies retool to make the parts economical using more recent technologies?
