Very much enjoyed, thank you for doing this! 24 years ago, I worked at an optical storage array vendor back from 1995 through 1998,, and our latest primary logic chip was considered groundbreaking at 450nm, which we developed collaboratively with Symbios Logic (I was just a lowly QA engineer in my Sr year of high school).. After I left, the company eventually closed their doors in 2001 with their half of the rights to the chip technology sold to Symbios Logic, who at this point had been acquired by LSI Logic, which was eventually merged with Syntax and renamed to Engenio Information Technologies, who later spun off it and sold Engenio to NetApp back in 2011 for about $500M, who still makes and sells storage systems based on Symbios Logic technology as NetApp E-series nearly a quarter of a century later. It's crazy to realize that the storage logic controller technology we developed back in 1995 is still the foundation for Enterprise storage systems being produced today, and has probably been part of at least 1 trillion USD worth of storage systems sold over the past 25 years, and any of us that have ever used an LSI logic storage controller has run at least some of the storage IO logic that we developed so long ago. Also amazing is that I still find this stuff so interesting and exciting.

7nm is about 20 silicon ATOMS. Crazy to think there are billions of transistors in a modern chip

Really cool analysis. One quick comment. Few years ago, TSMC naming scheme for its process started to reflect the smallest feature it can print on a wafer, which is a "fin" of a finfet transistor. Therefore if you measure width of a fin (3D structure orthogonal to the gate), it should come out closer to a "7nm" give or take 1 or 2 nm. - at least for the first generation 7nm. But of course this makes measurement under the electron microscope that much more challenging. Intel 14nm still adheres to a older naming scheme, but it is roughly equivalent to TSMC 10nm half node process. Thought the ++++ may have shrunk it down to closer to 9nm. Most importantly the characteristic of the transistor is quite different. Ex. TSMC 7nm transistor can operate at a lower voltage and requires a lower voltage to turn it "on" or "off" at the gate. Therefore its dynamic power dissipation tends to be lower than that of Intel's 14nm per unit area.

@NizarElZarif

I think the Intel +++ is more about improvement in 3D fin structure for more frequency range, lower voltages, and higher yields rather than density improvement. I think they all know that now this is more of a marketing term that a physics. They know consumer cares about having smaller number so they give this.

Self-aligned multipatterning and immersion lithography. TSMC used to use DUV for 7 nm but now use 13.5 nm EUV wavelength of light and features are approximately the same size as their old DUV 7 nm process. The wavelength of light is less relevant than you expect and improvements in lithography happens much faster than the improvement in light source.

Samsung is probably the worst in this regard, where 14nm is basically a FinFet of a version of their 20nm with no improvement to density (but huge improvement to power efficiency and frequency because of FinFets). their new 8nm used by Nvidia is an Nvidia optimized version of their 10nm.

So intel or amd or any foundry for that matter could "move" to a smaller node just by making optimizations to the existing one and changing the name
