The Shared Materials Instrumentation Facility (SMIF) is the Pratt School of Engineering’s core facility that enables materials, devices, and integrated systems research at Duke University in a variety of fields that include nanotechnology, biomaterials and biomedical engineering, information sciences, optoelectronics, sensor technology, and renewable energy. SMIF is housed in the Fitzpatrick Center for Interdisciplinary Engineering, Medicine and Applied Sciences (FCIEMAS). The facility consists of 7,000 square feet of clean room fabrication space, and nearly 3,000 square feet of specialized laboratory space for characterization and imaging equipment. SMIF is part of the Research Triangle Nanotechnology Network (RTNN) in partnership with similar facilities at North Carolina State University and the University of North Carolina at Chapel Hill. The RTNN is one of 16 organizations nationwide that comprise the National Science Foundation sponsored National Nanotechnology Coordinated Infrastructure (NNCI) program.
SMIF is open to all trained students, staff, faculty, and researchers and is used for both research and educational purposes. SMIF has nearly 700 users, of which 2/3 come from Duke University and 1/3 come from external academic institutions or industry. SMIF staff trains students and researchers to use the lab equipment and instruments themselves, and provides guidance and support in developing processes and methodologies that utilize these capabilities. Alternatively, SMIF staff can run samples for researchers as a service. SMIF also coordinates various educational and outreach activities.

It's always interesting to see how much textile technology has guided computer technology. This is essentially the same process that is used in screen printing and even older wax resit methods(such as batik). And of course, jacquard looms are proto-computers.
this is exactly what i've been looking for and very thoroughly explained. thanks a lot!
Wonderfully done, informative and well produced! Thanks for taking the time to create these and sharing them!
This was an INCREDIBLE video!!! I have been helping a semiconductor fab do the CAD drawings for the new tool install so i spend a lot of time around all of these machines. I had no idea how they or what the process was but this totally explained it! Thank you!
A really wonderful explication of the complete photolithography process. Thank youuuuu.

Very helpful, thanks for putting this on KZread!
Nice! This series is a great introduction to semiconductor manufacturing. Lithography is an important part of the process, repeated many times to build a circuit.

Glad you enjoyed it!
your explanation is awesome I had a problem to understand this part but I understand this from you despite I am not good in english so thank you
Nan makes me feel like a Neanderthal. Beautifully delivered talks / lectures, thank you.
these are great short learning templates. Thanks for producing them
perfectly explained! nice pace! beginner friendly
thanks for the detailed information!
this is excellent for beginners, it explains thing simply from the ground up, well done !!!
I used this video to get a job I'm woefully under qualified for.
Great videos to learn about semi conductor processes
Great video, thank you!
Awesome content on Photolithography with the real equipment and quite nice explanation.. thank you so much guys! Keep it up!😍

thank you for such clear explaination
Thank you very much for the video. Could you tell me what are the possible causes of stitching lines? why some lith machine macke stitching line during the lith process an other machines dont have this problem? thank you very much!!!!!
Great video. Really helpful!!!

So useful thanks alot
Hi ! In the example used with Gold , isn't Gold a photoresist? Because you had the silicone, and then on top you need to have a photoresist directly, but there was Gold .. so is gold = photoresist ? Thanks for the video !
Very good explanation
Awesome
Very descriptive. Thank u❤️

Thanks alot
why do we need to inscribe patterns on the substrate??
great
does diffraction soften the pattern when transferring the pattern?

You need to watch Huygens Optics latest video. Both the light source and the mask is needed to be designed/adjusted by counting the effect of the diffraction. So much in fact that both the light source pattern and the mask look like a diffraction pattern themself (-for layman at least).
Great presentation, shame about not showing the gold layer process though. I still learnt a lot though, thanks.

where im gone get a cooking pan to make this dice ,taste the best ?
Very good video. I'm still wondering though, if they use this process to get parts 7um thick, how do they get things down to 2nm? I read 1nm is 1000 times smaller than 1um so how do they get any accuracy at the nm scale? How do they manage to line everything up when when it's only tens of atoms wide... Also the wavelength of ultraviolet light is wider than these dimentions anyway so how is it even possible? My head hurts!
