@@mecha207 That is a cool idea. Could also do a series on the different machines used. Everyone only talks about the lithography machines but there are so many deposition, ething, plating, cleaning, melting, cutting processes you could make a whole channel. The story of how modern chip lead frames are produced is pretty cool as well. They used to be etched and really expensive until this Chinese guy from a progressive stamping factory took a tour of the semiconductor museum in Japan or California, and saw them there. He knew he could make them much faster and cheaper. He pretty much cut the price of production 100 fold over night. The story of the wafer dicing saw blades is also really interesting. They are really fast spinning "foil" discs. Or how Japan came to be such a transistor powerhouse and the calculator wars.

I'm not a scientist or a part of the tech industry, I'm just a humble truck driver with a curious mind. Hell, I barely understand how a transistor works. But watching this series on EUV is absolutely blowing my mind, even though I only understand like half of it. Mirror so perfect that it would look absolutely flat even if blown up to the size of the United States... generating this impossible ultra-ultraviolet light by shooting drops of molten tin with a laser twice, 50,000 times a second... and then the transistors on the chip are so tiny that we can't even see it, even with a electron microscope! And yet it works, and I can buy it at Best Buy for a few hundred bucks. Amazing what humans can come up with

Yes, this is not intuitive. My guess ... take it with caution!... is as follows: Bragg's reflection of a single beam ray from multiple layers of materials of different refractive indexes results in the lateral shift of the ray's shadows, which represent "reflections" from deeper layers. The multiple mirrors arrangement may result in the compensation or attenuation of these "Bragg's shadows", and/or possibly? averaging nano-geometrical distortions in the system. In general, “diving” into the science behind ellipsometry of thin optical layers could help better understand the intricacy of the whole design, ...which is a challenge in itself 😉!

@@joshuahuang5798 That makes sense.It looks like they progressively reduce the angle and as Michael mentioned the layers can cast shadows, which I have read before as well. My guess is they need to compensate for the shadows while maintaining other limits or setup the angle for a clear top down projection. I don't know if the error averaging is correct because a lot of errors multiply through reflections. Would love to learn more about this.

An important additional point is that the plasma produces multiple wavelength of light, but the distributed bragg reflectors are very selective which wavelength they reflect - to the point that the angle changes the best reflected frequency.

The reason ELLIPSOIDS vs PARABOLIC shapes (or paraboloid) are used is because parabolic reflectors reflect light from the FOCI parallel to an imaginary line defined by that foci and the parabola's asymptote / apogee. That's to say, rays reflected will be parallel that line (along with diverging rays. An ELLIPSOID however, allows focusing reflections at the other focus. Single-reflection rays (photons) emanating from one of an ellipse's two foci will be focused (converged) at the other foci ... which I'd presume to be the wafer / mask, etc., in this case.

Great exposition as always. Just want to add some physics-related corrections. Bragg reflection needs many layers not because one layer reflects not enough light. Indeed, one layer reflects pretty much nothing. Many layers are needed to produce coherent superposition of scattered waves in such a way that much is reflected and little is transmitted. It's pretty much the opposite to the photographic lens coating which is also multilayer these days. Second, the flare "much loved by J J Abrams" is in fact due to the use of anamorphic (cylindrical rather than spherical) lenses for wide-screen film photography. On the other hand, rms of mirror/lens surface leads to imperfect focusing which pretty much looks like your 5nm machine has resolution close to say a 10nm one. Having said that, I truly admire your dedication: I would never in my life want to sift through dozens of conference papers on the topic. Thanks again!

This process could also be considered a new branch of chemistry when atoms replace neutrons (e.g. Si|Ge). I think crude, not so deterministic neutron variation is utilised as a tool to speed up the genetic modification of plants. What is only required is adequate "optics" for high energy neutron beams. It shouldn't be difficult, should it?!
