I have a question about e-beam evaporation. Metal is definitely heavier than the air, then by how they can goes up? I think they will behave more like dry-ice. So I think it is good to place the wafer(substrate) on the floor of the chamber, not on the top. And if they(gaseous metal) can move freely in the vacuum chamber, do they also stick on the wall/surface of the chamber?
During the process we set the deposition requirement, ex: 20nm, and a pre set value of deposition rate "X"nm/s time is determined. Post deposition the thickness may be measured using Ellipsometer.
There is a measurement system near the sample, which is made of silicon cystals. The weight of deposited film is atomic compared with the crystal. The crystal has an oscillation. When the material becomes heavier, the oscillation changes.
You guys are awesome 🤍🤍...loved this video
one of the best explainations i have ever gotten. Thank you so much
the explanation is out of this word. Thank you so much, you helped me a lot understanding the 3 different techniques
Great to hear!
Yep, I worked with one of these, for InSn deposition.
Loved the explanation! Thank you so much!
Beautifully explained.
Thank-you for posting this video. The information is very clean and easy to follow.
Really nice explanation
Thank you
Thank you so much. It was so nicely explained.
this guy cracks me up 😂
The best explanation everrrrrrr
just wow!
thank you, excellent explanation ability
it really helps! I'm doing a homework about PVD(E-Beam deposition, sputtering, thermal deposition)
Great explanation
U r doing great
Very good explanation 😍🌹 thanks you
thank you very much
Is there any pos doc vacant??
very good
Excellent
Indeed!
Thanks. that was helpful!
thank you for your explain
You are welcome!
Thanks

Is that have any subtitle or text of explain ? I cant understand ,
Thank you very much!
well done
Really great video
Glad you enjoyed it!
How can you check the thickness of the thin film during the process?
During the process we set the deposition requirement, ex: 20nm, and a pre set value of deposition rate "X"nm/s time is determined. Post deposition the thickness may be measured using Ellipsometer.

Why didn't this student get an introduction? Lots of missing B-roll too
Nice!
Dr. Ozdemir video recomendations are good right! Super easy and fun to watch
Agreed Luis. I recognized the student in the video too - was surprised to see him haha
who can help to translate it? I can't get the meaning very well
👍
