The actual discovery is reported in one of the last paragraphs:

>The breakthrough relates to a new set of materials that can create monolayer—or two-dimensional (2D)—transistors in a chip to scale the overall density by a factor matching the number of layers. The teams at TSMC and MIT have demonstrated low resistance ohmic contacts with a variety of existing semiconductor materials, including molybdenum disulfide (MoS2), tungsten disulfide (WS2), and tungsten diselenide (WSe2).

So it is a better way to make a contact to a semiconductor material that noone knows how to manufacture reliably on a large area wafer.

It took 25 years to commercialize EUV. And that is from the point where a decision was made to industrialize it, not from the first scientific report about EUV radiation.

edit, see Zeiss page on EUV: https://www.zeiss.com/semiconductor-manufacturing-technology...

so this is again one of these "material x was slightly better in a lab experiment" -> "we conclude that it certainly can be used as part of a complex technology" press releases.

I am not too fond of this, but obviously thats the easiest way to explain the significance of research results.

Getting a new material into a semiconductor manufacturing process takes years or even decades. Whatever material will be in TSMCs "1nm" process, it is already known.

SiGe is used since the 90nm node as source/Drain material.

Book looks well made. His youtube channel seems to be here:

Control theory is a really fundamental topic that is useful in many disciplines. The field has some very pragmatic approaches.

I know nothing about this, but this passage in the Wiki article that you linked points at some controversy:

>While Malone promotes himself as an inventor of mRNA vaccines,[1][7] credit for the distinction is more often given to the lead authors on the major papers he contributed to (such as Felgner and Wolff), later advances by Katalin Karikó and Drew Weissman,[3][19] or Moderna co-founder Derrick Rossi.[13] Ultimately, mRNA vaccines were the decades-long result of the contributions of hundreds of researchers, including Malone.[3][20] The New York Times, in an article about Malone, reported: "While he was involved in some early research into the technology, his role in its creation was minimal at best, say half a dozen Covid experts and researchers, including three who worked closely with Dr. Malone."[7]

>Russia's actual interest here is to trade gas for money

You are underestimating the complexity of this issue. There are long term delivery contracts that force Gazprom/Russia to deliver. All the things you are seeing are thinly veiled attempts to create a "force majeure" exception as a superficial narrative to shift blame and still cause damage.

Don't be naive.

>The cargo -- 137,000 cubic meters -- will be delivered by Abu Dhabi National Oil Co. to German utility RWE AG by early 2023. ADNOC also signed a memorandum of understanding to make more deliveries next year.

>After the UAE, Scholz traveled to Qatar, where he and the nation’s emir were expected to discuss long-term plans for shipments of gas and hydrogen. Germany and Qatar have been discussing LNG supplies for several months, with Germany being reluctant to commit to long-term contracts at record prices for LNG.

Clickbait title.

>Nord Stream 1 is broken due to sanctions on equipment repair

It's well known that this is not true. You are perpetuating russian propaganda.

Without tax, I assume. For people in other regions tax will be added now.

Yeah, twitter is broken for me too.

He stepped down from a full time role years ago. I believe the 20% is no change.

The interview with Lex Fridman that he was referring to:

The entire video is worth viewing, an impressive 5:15h!

a very persistent person seems to try to convince HN that the big bang did not happen. fifth submission today?

A schottky junction solar cell, as mentioned in the article, can easily be produced with common household articles:

How is Micron a "tier 2" company? They are probably the oldest surviving DRAM company and have always been in the TOP5.

No idea about their payment, but i met some of the engineers who work there and they are extremely dedidcated. I don't think they are shopping around for other opportunities to maximize they pay, like it seems common in the bay area.

He keeps doing it despite frequent complaints. Troll-marketing?

That's an extremely naive thing to say. Do you think the root cause of this does not apply to other European countries? Namely, faltering supply chains in Asia, skyrocketing energy prices?

>The more people, the more scaling.

This is what brought us scientific and engineering progress.

The problem is, of course, that growing inequality stalls these mechanisms.

NewsBlur is pretty good and does exactly what it is intended for.

Wow, very impressed by the free Chapter 1. I like that it does not only look at integrated circuit, which have been covered many times already, but also looks at passives and discretes. The image quality and sample preparation looks to be top notch.

This doesn't even cover all the neat assembly tricks with self-modifying code that you would actually use on a 6502 to speed up memory transfer.

I was hoping for something more insightful. What are real mitigation options other than sitting it out?

The technology used by PragmatIC is not based on organic semiconductors though. The only organic material is the substrate (Kapton, I assume).

The transistors are based on IGZO (Indium Gallium Zink Oxide), which is a relatively new material and is an amorphous high-channel mobility wide band gap material. The transistors are not as fast as LTPS, but have much lower leakage. Since the material does not have to by crystallized, it can be deposited at fairly low temperatures on plastic subtrate.

You may very well regard IGZO as the plastic electronics killer, because it does everything that PTTT/Pentacene etc. was supposed to do. Noble prize? Let's see.

Sadly, IGZO is not a rival to silicon when it comes to power efficiency, speed, and cost per gate. So these MCUs are nice demonstrators, but the use case is doubtful.

IGZO is great for display, large area sensing and possibly memory.

p.s.: Congrats on the research, very interesting paper! I am long out of the field, but still amazed about the progree being made. I wonder, what does the high ionic conductivity mean to device stability, especially if used with a field effect device?

It's one thing to build a few samples, it's another to mass produce with high yield. The GDR produced a 1 Mbit DRAM chip with great fanfare, but was never able to mass product it with commercially viable yield.

Is this a joke?

Edit, yes it apparently is: Initials spell "STUPID"

GF in FDX22, possibly also with eMRAM noadays. Surely not sure fathers 2010 cmos process...

>Much of critical blockers for chemicals, consumables, materials will still be in Taiwan just because the semi industry is that huge there.

You mean like Linde, Air Liquide, Dow, Merck, BASF, Entegris, Shiply, Fujifilm, Wacker and so on?

Those are not Taiwanese.

>Germany used to have a semiconductor industry like Intermetall (acquired by micronas acquired by TDK). The problem is that IMHO German automotive industry is not willing to pay a cent more than necessary.

How about the three fabs that Bosch has in Germany? Or Infineon, X-Fab, Globalfoundries, TI, Prema, Elmos (now Siltech), Vishay, Nexperia?
