- E-beam lithography is the process of directing an electron beam across a resist layer and thereby creating a pattern that can be etched. Structures of 20nm can be produced. This is the technique that is often used to create nano scale waveguides and microring resonators. One type uses an scanning electron microscope equipped with special beam control software. The other far more expensive method is a dedicated e-beam facility that is able to etch structures directly.
This video is part 1 of a 3-part series.

This is really helpful, thanks.
Each video is amazing and instructive! Thank you so much.
Informative indeed. Thanks!
Excellent tutorial for beginners.
Like your videos so much. Very helpful.
Very informative.
thank you very much for the video. Could you please tell me what are the reasons of the apparance of the stitching lines und why some lithography machine cause this problem and other dont cause this problem?? thank you!
Excellent tutorial
Awesome stuff.
amazing lecture.. grattitutde
the clean process is so inpropriated
do you know if PPC is used as a 'resist'
great stuff! I want to build my own e-beam lithography machine , where can I find sketches on how it works?
You build a scanning electron microscope with an unfocused beam and hook the defelction coils up to a custom analog cnc controller. Like, really, finding diagrams is the easiest part, try looking at research papers paper on the topic, that's always a good place to start. This would be a humongous undertaking to build if you don't already own a working microscope
i want to have some plasmonic nanostructures using e beam lithography. is their any university/institute which can produce them on payment ?? guide please.
Very interesting
good video
There is another E-beam application .@eVtQ
Also, your PMMA is probably dissolve in anisole, which is not good for your body. You should conduct all your spin coating in your fume hood, and safety glasses on!
Why do you specifically use pure nitrogen to blow excess water off the surface? What's special about nitrogen in this case?
+Sercan 't Nitrogen is in 78% in our atmosphere. It is also the seventh most common element in the Universe. It is an inert element when oxidation is undesirable, i.e. it doesn't react much with matter, thus it is very safe to blow the wafer with it. The reason for using "pure" one now is clearer, since if not, you might get some other elements that does react with the wafer.
Thank you both for taking the time to answer.
why they still use uv light? because they are still in solid state transistors, micromechanical relays go to pico sizes
cd-burn, also you can do e-beam mask
Where are your safety glasses?
We never break wafer like this......man......always scratch the back and break from the front, so you won't damage the front surface.
the cutting can cause dust, bad for eB L
