Carl Zeiss, Explained: Germany’s Semiconductor Optics Master

Germany-based Carl Zeiss AG is a fascinating company. Fascinating, even if you do not take into account that they make lenses and optics for some of the coolest systems in the world.
When you are etching patterns as wide as a small virus, you have graduated beyond simple lens. Now we refer to them as "optics systems". These massive multi-component systems are at the very heart of the multi-million dollar photolithography machines that ASML makes. Without them, ASML has no machine to deliver to TSMC, Samsung or Intel.
In this video, we are going to continue with our deep dive into the semiconductor industry’s critical suppliers with a look at one of ASML’s closest partners. The makers of the optics systems that let high-energy UV light etch wafers. And a company with an utterly fascinating history. Carl Zeiss.
Error: The video shows that Zeiss died in 1866. He died in 1888.

Zeiss had fantastic story. Outside of the semiconductor work I like the story of the camera optics in the USSR and the Helios 44 lenses which are descended from the Zess Jena Biotar lens. Also in the interwar period Nikon lured some engineers to Japan to help with optics and kickstart the Japan optics industry. A huge part of the modern world is built directly and indirectly on the early work of Zeiss.

That the mirror system in the EUV system are some of the most extremely complicated and finely tuned things you've ever run in to, I'm quite willing to believe. I've heard and read some things about other parts of the EUV machine myself, like the light source, and those create the exact kind of feeling in me as well. As some of the most insanely sophisticated pieces of engineering you've ever heard of. Probably quite a few things in the EUV machine are like that I guess and it really explains why the costs of developing it were so high, or why unit prices so high. And yeah, it really makes you wonder if anyone else can any time soon afford to develop a competitor device. Frankly, especially with hindsight on the costs and extreme engineering involved, it wouldn't have been that surprising if the semiconductor industry had failed to make this jump and just stalled out at around 10 nm or so for a good long while. They almost didn't make it as it is, what a different semiconductor world that would have been.

If 20 years ago you had proposed building an EUV litho system with current-generation engineering and performance spec's, people would have thought you were completely out of your mind. If you showed them such a system they would have probably thought it must be space-alien technology.

[@cogoid]

These are incredible machines, for sure! But 20 years ago everybody thought that conventional lithography was on its last legs, and a switch to the EUV machines was just around the corner. Intel, other large manufacturers and government laboratories have created the EUV consortium just around that time, and the pieces of the EUV machines were already working in the labs. Intel hoped to have 13 nm EUV in production by 2007 and beta versions sooner than that. But it turned out that with various tricks one could print some features that were much smaller than the wavelength of light, using relatively ordinary lithography, so it just kept going and going. *That* would probably be more surprising to the people from 20 years ago!
