Comments like this are why I love HN, I didn’t know anyone was considering sub-nm in anything beyond a random though, that is quite astounding.
Engineering in the billionths of a mm, alien technology to anyone born when I was born in 1980.
- thechao 6y agoThe smallest half-adder is just a double fistful of atoms — about a million times smaller than the proposed 2nm GAA logic. The doubling rate is going to slow down, so we’re talking ~20 generations of at least 3+ years, or more. Who the hell knows what things will look like in the year 2100.

- imtringued 6y agoTransistors have been manufactured as a 3D structure for more than a decade and they have multiple dimensions. The idea behind process node naming was primarily about how big a planar transistor would have to be to provide the same transistor density. However, since vendors can slap whatever label they want on their process that's what they end up doing. If you want to compare manufacturing processes then simply compare transistor densities. That way you will avoid the paradox of thinking that the physical limitations of an old transistor design apply to a chip that is using a completely different design. Here is a list of different possible designs [0]. [0] https://www.extremetech.com/wp-content/uploads/2019/05/FET-Types-Samsung.png https://www.extremetech.com/wp-content/uploads/2019/05/FET-T...
