It's still a marketing term that has nothing to do with specific feature sizes, but they do increase density from one node to another. https://en.wikichip.org/

- dwaltrip 7y agoHow are the numbers chosen if they don't correspond to any actual measurement?
- wolf550e 7y agoLike the numbers in product names, only with the understanding that smaller is better.
- ip26 7y agoWell, the old law was that density doubled with each node. Indeed, you can see that e.g. from TSMC7 to TSMC5, density roughly doubled, regardless what happened with minimum feature size.
- blp 7y agoIt is an equivalent scale. Density is fine pitchm2 pitchtrack height. You scal node by an equivalent reduction. It would be better to use logic density, but it is easier to use numbers we are used to.
- wmf 7y agoThe numbers are a factor of the square root of 2 since that reduces area by 2.
- Rexxar 7y agoThey divide by sqrt(2) and round to an integer.
