as china has learned,, you just cant poop these custom circuits out as easy as we make it seem ..
The chip fabrication technology just went through an upgrade from 11 nanometer to 7 nanometer feature size. The smaller size means faster speed and lower power. Much of the 5G products are depending on the 7nm as are the new memory devices for servers. Intel does their own fabrication and were behind the curve at 12 nm and they could not get their 7 nm processes to work. Taiwan Semiconductor Manufacturing (TSM) is the largest and probably the most advanced commercial chip manufacturer in the world. Many chip designer companies have their chip fab done by TSM. I would guess Intel will go to TSM as an interim work around. China tried to build a chip fab plant and it was a total failure.
