Taiwan Semiconductor Manufacturing Co. has set a roadmap for its N2 (2 nm-class) fabrication process, which will enter high-volume manufacturing (HVM) in 2025, it is time for the company to begin cons... TSMC Will Begin Process Technology Research at 1.4nm
That is just insanity how small that is. A DNA strand is 2nm. I wonder what is the smallest they can go. then once they hit that, whats next?
There was a time when the number of a process node related to the gate length of a transistor. For a decade now, that the number in these process nodes have no correlation to real physical dimensions.
No. Like I said, these numbers are marketing. But producing smaller chips is getting exponentially harder and more expensive. A silicon atom is 0.2nm. 0.45 if we consider the atom's lattice. For example, on TSMC N7, Contacted Gate Pitch is 57nm and Minimum Metal Pitch is 40nm.
