Well gunpowder is China's idea, so yeah you all must stop using all iteration of ideas that comes from gunpowder. No gun, rocket, car, missile. Oh yeah paper also China's idea, as well as saw. So yeah you all should go back to stone age. What an odd way of thinking isn't it?

despite hiring many ASML engineer, this machine is not reverse engineered. they use a completely different light source which was abandoned by ASML as a development path. so basically they dug an abandoned solution from the grave and make it work. all these information was out there for close to a year now with scientific paper documenting it. US need more people who are STEM that can read Chinese who ain't Chinese so they can understand what Chinese are doing. China is actually a very open book if you know how to navigate it academic infrastructure to find all the documentation, being the inventor of papers and so paperwork, China love to document things.

Is worst than that. Reuters lie, China is not reverse engineering anything. China is developing EUV LDP which is a tech that they have been developing since 2016 with their own patents. While ASML use EUV LPP that has a lot of patents and is not possible just "copy" it because require a lot of components all patented by ASML and USA. That also means that Ex-Engineers (or even current one) from ASML CANNOT help China at all to develop LDP EUV because they have not experience AT ALL with that technology. The Reuters want to implant the idea that China is reverse engineering to justify future sanctions and make the people to believe that China cannot make anything by their own. Any time a news media says "anonymous source", that means is made up by themselves.

Naturally when America was the new kid on the block it stole every idea it could. Not satisfied with the ideas it then stole the raw materials. STILL not enough? Lure other nations best and brightest to come here. BINGO things really take off. Until today..

By saying China relies on reverse engineering ASML machines, Reuters is trying to emphasize that the Chinese can only copy ASML and can't design their own EUV machines.

Apparently the so-called "reverse engineering" has been debunked/clarified by this explication in another report: The Chinese EUV is LDP EUV which is completely different from the ASML one which is an LPP ASML machine. LPP cannot be replicated because of its patents in many areas. China have been working on LDP technology since 2016 and has a lot of patents associated to this tech. Hence, Reuters lied when citing "anonymous sources" to implant an idea in the minds of people that "China cannot do it by itself, is doing something illegal and with help with ASML engineers in the shadows" This makes no sense at all, because no ASML engineer can help the Chinese develop LDP EUV because it is completely different from LPP EUV.

China reverse-engineered EUV from nothing, while the U.S. extorts other countries.

Reverse engineering can only be done if you have the material to "dissect," bro, and for that, you have to have a brilliant brain. And to produce a set of SUV lithography machines... ASML has to collaborate with dozens of countries, so imagine how genius China would be if it could do it independently 😂
