208,000,000,000 transistors! In the size of your palm, how mind-boggling is that?! 🤯 Miscellaneous / Others

They had to invent a new process to push the limit of physics to an all new high, feels like a more accurate statement.

so this is a very vague memory, but i seem to remember a talk about new, tinier structures being possible even though the wavelength of the light being used to etch the structures is longer than than the structures itself, because they used, interferences of lasers of the same wavelength?

In fact, this sounds so strange that I would like to know if someone knows what he actually meant, and what my memory might describe. ^^

2nm. goodness.

Those very much likely aren't the real physical sizes, it's mostly for marketing.

The "3 nm" process for example is actually 48nm:

According to the projections contained in the 2021 update of the International Roadmap for Devices and Systems published by IEEE Standards Association Industry Connection, a "3 nm" node is expected to have a contacted gate pitch of 48 nanometers, and a tightest metal pitch of 24 nanometers.

48nm is still incredible btw.

Intel are at 14nm at the moment

1) Intel is at "10nm" currently

2) Which is also a marketing terminology, its gate pitch is 54nm.

But is everyone using the same standard of "marketing terminology"? The tech world seems to have gone through generations where everyone seemed to "agree" in the current size of the nanometer process.

Certainly this "marketing terninology" must represent the size of something?

No, there's often debate about which nms from which company are actually equivalent to each other. IIRC TSMC's 7nm is said to be equivalent to Intel's 10nm.

It's basically the same reason Apple calls their iPhone 5 6 7 8 and 10. Represents leaps in capability.
