News American lab is developing a BAT laser that could enable 'beyond EUV' lithography, provide 10X power efficiency boost

Petawatt-class thulium lasers could replace CO2 lasers in lithography machines down the road.

So still EUV but with a more efficient laser source.

" 54,000 gigawatts (GW) of power per year " is gibberish.

It can't be 54,000 GW, because total world production is only around 3,000 GW. So presumably it is 54,000 GW hours per year.

Another excellent article from Anton.
It should be noted that the current EUV technology deployed by ASML originated at this lab (see Wiki "Extreme UV Lithography")

It's fairly common for journalists to confuse watt hours (energy = power X time) with watts (power). I wonder if that is the case here?

6GW (6000MW) run 24 hours a day for a year would use roughly 54,000 GW hours. That'd be over 5000 of the current CO2 laser based EUV machines. (That'd make ASML a lot of money.)

Wikipedia lists the world total electrical capacity (not usage) at 8,890 GW.

Nice article, but some of the arithmetic seems dubious.

The power consumption of modern EUV tools and fabs has led industry analyst firm TechInsights to raise the alarm over the power consumption of semiconductor fabs.

I wonder how many Joules of energy are needed to make each CPU or GPU. Another relevant figure would be the typical (and max) Joules it's likely to use over its lifetime. Then, compare the two figures.

I'd say we really have a problem on our hands, once the production energy is within the same order of magnitude (e.g. above 10%) of the usage energy. Until then, the energy usage by fabs is probably more of a problem for the locality where they're situated than a problem of global energy consumption. Either way, sounds like a problem worth trying to tackle.

Thule available for color comments, requested rename to match regional current name of Qaanaaq (This a BAQ laser?) Open Access in Optic Sex Press so only a matter of a couple years until health uses are fielded for this 413 eV - photon (coherent though, so feels like 170 kV photons) light source. Who knows the antioxidant excitons with that energy?

ETA: Maybe a nice adiabatic laser chiller for Zen 5 to not cook power users at their laptops? Just run those nVidia chips where they draw 1/12 the power and send 1000 IR photons plus Raman gain out a clear bit of sky. (SERS BAQa chillers?)

If you read the source article it cites the machines by themselves only make up ~6000 GWh of the 54000 GWh figure (it also cites up to 10.2 GWh annually per machine).

How can we have an article about a BAT Laser without a picture of Adam West? 🙃

 

[bobkn]

If you read the source article it cites the machines by themselves only make up ~6000 GWh of the 54000 GWh figure (it also cites up to 10.2 GWh annually per machine).

Should I have to read the source article to rationalize the stuff here?

If you're trying to be accurate perhaps you should click the link in the paragraph you're attempting to rationalize which led to a Tom's article that had this in the text of the article (and provided a link to the source which I used):

6,100 GW/year — power consumption comparable to Luxemburg's — is not a lot. However, each advanced chip takes over 4,000 steps to make, and there are hundreds of tools in a fab. EUV equipment accounts for approximately 11% of the total electricity use in a fab, with other tools, HVAC, facility systems, and cooling equipment making up the rest. As a result, the power consumption of all fabs equipped with low-NA and high-NA EUV tools is estimated to increase to 54,000 GW/year.
