Do we need 2nm chips?
Samsung expects to have 2nm chips in mass production by 2025 and plans to deliver mass production using a 1.4nm process by 2027, aiming to expand the capacity of such advanced process nodes "by more than 3X." The plans were detailed by the Korean electronics giant at its annual Samsung Foundry Forum event in San Jose, …

What exactly is a 2 nm process ?
If you think about the Van der Waals radius of a silicon atom, it is about 210 pico-metre, so 2 nanometres of distance would be nearly 5 silicon atoms wide. And 1.4 nanometres of distance would be just over 3 silicon atoms wide.
And if you step back and think about dopants used in a semiconductor, it is typically that one dopant atom is added per 100 million atoms to change them from an insulator.
So I'm guessing that a "Samsung 2 nm process" is a 100% made up marketing name to shift more product ?
