Wondering how they're flattening the droplets if they're not using a laser pre-pulse...

？？I don't remember I ever post the "same shit" before
This thread is full of translated article from ijiwei website，am I right？It's just an indication that people trust news from this website
Looks like they are using some kind of device to flatten the droplet in order to use only one pulse.
Ijiwei’s article is just a translation of the bloomberg article.
“集微网消息，据彭博社报道”
Did you even read the article?
Here is sleepy’s post

Starting by making parts for EUV is quite ambitious to say the least.
Well, the tin droplets are being created by a droplet generator. That seems to be the only droplet related device in the patent. Based on their diagram it seems the droplets are naturally flattening on their own as they're being dispensed. The only possible way I can figure this happening without further mechanical manipulation is if the droplets are being dispensed orthogonal to gravity, are flattening as they fall, and then are being excited from below. But that makes me wonder how everything in the instrument is arranged to avoid intersecting with the emissions path and to collect the debris. For example, where would the droplet catcher go for the dispenser, and how would you avoid the dispenser being in the way of the emissions (I suppose they could eject the droplets with some force, but then I wonder about variance error)?

I have my doubts the YMTC will get off the list that easy, the China hawks had been keeping an eye in this company and has been advocating to export control them in their delirious boring talks since few years ago, as well CXMT.
The US Commerce department is suppose to move those "uncooperative" companies from UVL to blacklist by 2022/12/06，but we haven't see any new announcement yet. I guess we have to wait until the US update the blacklist to confirm which companies are exempted
Yes. He’s like a bad case of fungal infection that just wouldn’t go away
