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.
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?

the explanation is out of this word. Thank you so much, you helped me a lot understanding the 3 different techniques
Great to hear!
one of the best explainations i have ever gotten. Thank you so much
Me too
You guys are awesome 🤍🤍...loved this video
Loved the explanation! Thank you so much!
Great to come across your videos
Thank-you for posting this video. The information is very clean and easy to follow.
Beautifully explained.
Really nice explanation
Thank you
Thank you so much. It was so nicely explained.
Yep, I worked with one of these, for InSn deposition.
this guy cracks me up 😂
The best explanation everrrrrrr
thank you, excellent explanation ability
How can you check the thickness of the thin film during the process?

just wow!
Is there any pos doc vacant??
Great explanation
Very good explanation 😍🌹 thanks you
U r doing great
Is that have any subtitle or text of explain ? I cant understand ,
it really helps! I'm doing a homework about PVD(E-Beam deposition, sputtering, thermal deposition)
very good
thank you very much
Excellent
Indeed!
thank you for your explain
You are welcome!
Thanks. that was helpful!
who can help to translate it? I can't get the meaning very well
Thanks
well done
Really great video
Glad you enjoyed it!
Thank you very much!
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

👍
Why didn't this student get an introduction? Lots of missing B-roll too
