Sweet, man! It's really cool to see other DIY hackers getting into thin film tech. Your aluminum mirrors will create their own oxide layer and become quite a bit more durable after a few days exposed to atmosphere. For really good durability, you'd probably need to add another coat of something. Even though the experts will say that pipe threads are unacceptable in high vacuum, if you plan to operate at 10^-5 or higher, they'll probably be fine. Use high density PTFE tape on the threads, and wrap the tape onto the tip of the thread. I've tested this many times, and found it to work fine. I'm really curious to see what you make with your new setup. Congrats!
I'd be curious how close to this setup, in terms of usefulness, one would be able to use a plug-in residential wall vacuum or shop vac to create a similar vacuum/deposition chamber. I wonder about at home waterproofing electronics that are taken apart during DIY repair (regardless of whether the item/device had an ingress rating prior to the repair). It'd be a simple set of steps to add what could be a lot of extra peace of mind for DIYers and local-level electronics repair businesses.
This is incredible, I'm looking to build a high vacuum setup for coating telescope mirrors and potentially other optics, this is incredible inspiration!!!!
I have comment after watching this because your pace throughout the video was perfect! Very well done! Most RUclips videos require lots of skipping forward while nothing is going on so this was refreshing.
I built one like this to deposit gold onto 6u Mylar to make microphones. Very similar, though my diffusion pump had a electropneumatic gate valve and I used an Omron ZEN PLC to sequence the deposition once I got the times all figured out. Nice work on having low leakage! That’s always a challenge.
You're an amazing young man. You need an adhesion layer for your copper to stick, not a protective layer. Before depositing the copper, deposit 50 to 100nm of NiCr. I use an e-gun with nitrogen IAD and get good results for adhesion of other metals. I don't know if you can evaporate NiCr from a resistive source, but your sputtering gun should work.
fantastic and cool project. Here are some suggestions: Titanium vapor on quartz, quartz already looks fascinating, and titanium gives it a petroleum rainbow color. there are other suggestionson wiki for "metal coated crystals" At least it would be something you can sell, if quartz can bind the titanium durably, you can put in big old stones from quarries, where the quartz runs in brick sized pieces and get lots of different quartz metal home made precious stones :)
On the note of ideas: Diamong Like Carbon (DLC) is a bit easier than "Proper" Diamond, if i understand correctly. That and/or Proper Diamond (Not even optical quality per-se, just like diy tool coating even would be huge!) Would be my Vote "Plasma Assited Chemical Vapor Deposition" seems to be the standard, perhaps borrow from The Thought Emporium's Design for that Magnetron?
Hey dude this is super awesome, there isn't enough online about how to go about creating DIY evaporation chambers so thanks for uploading! One thing that is probably stopping you from reaching low 10-6's is the poor seals, O-ring copper gaskets would be a good value upgrade if you want to get your pump down time and absolute pressure reduced.
Interesting... Thankyou for showing this setup. I am looking at developing a prototype system for an open source Electron Beam Melt system in the relatively near future, and have a tendency to over-estimate challenges. The main difference is that I am looking at developing an ion pump to go from crude vacuum to high vacuum - possibly even integrating this into the electron gun, itself. There is also some additional experimenting I would like to do involving ion sublimation and nanoscale additive manufacturing. Current facilities are too limited to undertake, but I am building a knowledge base ahead of time.
I'm blown away by the stuff you're doing - It wouldn't surprise me to see you build a breeder reactor in the back yard., Seriously cool stuff. Technical note - I had trouble making out what you were saying, partly because you talk so fast, but largely because the background music was drowning you out. But hey, this is such a cool project. Keep rocking!
I don't know if it would work, but a copper deposition or some other material on a set of dragonfly wings might be pretty cool. I'm thinking something the right thickness that it starts to mess with the way light reflects and refracts, but hopefully without losing the appearance of them being natural wings.
Looks like the stuff I do everyday. I need to get back into R&D. try using RF to sputter oxides if you get around to doing those types of deposits. a 40khz plasma generator combined with an acetylene gas bleed has been known to create forms of DLC.
Nice Setup. it's amazing. I am doing the same thing for my thermal evaporator. can you please send me your specifications of MOT(current source) with its connections. I already become a fan of you.
Just drill out the high side of the MOT and wrap it 2 times with a piece of 2 gauge welder cable. It's that simple. you get around 1-2 volts out at around 800 to 1000 amps. Run it through a Variac to fine control your heat source. MOTs are all slightly different, but pretty much the same
Great work Ben, "But using Aluminium for the base plate" won't it contaminate the vacuum.I mean Aluminium Oxide is a great problem. Usually, Stainless Steel is used for the base plate material. Did you encounter any problem while depositing reflective coatings?
OK, it seems there are plenty of experts here and I have a question about something that has been bugging me for a long time. I grow crystals, I actually started with almost no practical chemistry knowledge which actually imbued with a very unique (naive?)way of attacking the problem of producing beautiful crystals. You can see some albums and single pictures of some pretty amazing stuff on IMUGR by just searching for "growing crystals at home". Anyway, I had noticed some entity in Arizona offering MAP crystals on a matrix with Cupric Sulfate Pentahydrate overlaid over the whole thing and it looks amazing. I wondered if they were using vapor deposition, or is there an easier way of doing it?
Hello Can you help me. When steaming copper sulfide in the thermal evaporation system, the steam does not rise to the top note that the dimension is 10 cm
Could you cover the substrate with something like a stencil, or would ALL the material come off when you peeled it off? It would be great if you could make circuit boards without having to etch them!
You totally can, I made a couple circuits! The traces are generally very thin and its difficult to solder to the traces, but you can deposit circuits on a wide variety of materials
Riyaz Ahamad If there's a thin film of oil coating the surface (often a diffusion pump will do this) just wetting it with acetone and wiping it off can remove all the deposited material. Some oils won't out gas much even under high vacuum conditions, but depending on your pumping methods it may be an issue. Hope this helps
nice video man! I am working on a similar project, rebuilding a old machine. having great times. I am not a specialist, so I trying to collect useful information, may you kindly help me: During evaporation metal, should the valves stay fully open and the Difusion pump working on? would this deposit metal film over the difusion pump spoiling it?
+fercarcas I left my pumps running during depositions and didn't notice any metal deposits on the pumps. It stays pretty well isolated across my big bell jar. with shields up. You may want to check with a professional if your using a turbo molecular pump, but metal deposits on oily surfaces just wipe right off anyway. Diffusion pumps are pretty resilient
Diffusion pumps often have a water cooled baffle separating them from your process volume to protect process from oil. Same will protect pump from bulk of deposition substances.
It's a really cool build. It kind of looks like a large Edwards Diffstak...those are more like $500-1500 used depending on size. How did you find one for $160? And the Edwards #5...looks like $300 is a better-than-average used price. How did you get such good deals? Even with lurking and searching those prices you list seem too low.
Im thinking of doing this too . a sputtering system from most companies will cost 100-300K easily. so man, if u can DIY me a 3 sputter head, 2 evaporation boat system and a rotating substrate holder that can do 800C. I have so many experiments i need to run. I would totally buy it for all of my life savings worth. i dono if that buying kinda stuff is even on the table when ppl do DIY projects on youtube. but either way... man. u and Ben krasanov are cool folks.
+adamklam1 Yea, that wouldn't be that difficult, it would just take a little more time to add the extra feedthroughs and sputter guns. Unfortunately I don't have the time for much of anything right now, but I urge you to give it a try yourself. If you can find a shop it wouldn't be very difficult. In my random building vid you can see me make a simple sputter gun, but I'd recommend a flourinert cooled sputter gun
A quality system with brand new parts and a custom chamber will likely cost in that range new. These parts are used and it's a hacky(which is amazing, not bad!) build.
how would one go about making >500 layers of 2 different patterns of conducting surfaces and 1 plane dielectric surface just 2 motorized plates that flip around systematically and change the patterns?
That would work, maybe tricky to position but you could do something with a the plates breaking a focused laser beam or a change in capacitance between two plates.
Dude, from where did you get this diffusion pump for 160$? P.S. I'm almost sure that casted/machined aluminium plate will be cheaper. It's just a guess... Sick project!
+magdanoz88 Ebay! I was kinda bummed getting the plate on Mcmaster at full price; I just didn't have the time to wait around to find one at a junkyard or something. I've seen some HUGE, beautiful pieces picked, like an 800lb, 6in thick 6ft wide Hexagin, machined mill-spec flat, marine grade aluminum masterpiece this guy I know got at scrap value price!
I'm going to buy a drill press and hole saw specifically for this project. Any general recommendations about what to buy? I see that you're using a floor mounted press here. Would a bench mounted press cut it? Do you find that a floor mounted press is handy in other situations? Hole saws are all pretty similar right? Thanks for the help.
I just used a bench one, its all I have. The distance from the chuck to the post is important, mine was too short for a couple of the blind holes so I had to use a drill guide. I would have liked to use a line boring/fly cutter type setup in a big mill than cut knife edges around it so I could use a copper gasket like CF flanges(totally unnecessary). The hole saw actually worked out really good, its just a 4" bi-metal one for the diff pump. Its nice because you can get whatever size you want up to like 6" and it doesn't need to be perfectly round as it just flows air. As long as it cuts aluminum your fine, just take it slow as they really bog down the weak drill presses and use some water soluble lubricant
BenNBuilds WD-40 (Water Denatured - Test 40) works great as an aluminum cutting fluid and a regular circular saw with a wood cutting blade will rip right through aluminum sheet. Ben could I pay you to build me one?
Diamonds are typically grown with chemical vapor deposition. I could use the chamber for CVD, but it would require a few modifications. Building a diamond CVD chamber shouldn't be too hard
Great man, and thx for your response first :D. so if you ever try to grow them keep me up to date i would love to be part of your experience. As for me i am willing to the same here but for commercial usage if you think you can help us out it would be more than a pleasure.
I want. Figure out how to grow some carbon nano-tubes and proceed to turn them all into MIM diodes for rectenna use (turn microwaves or even light into DC current!)
This is really cool! Thanks so much for posting. I want to build one in order to deposit a 50 - 200 nm thin film of gold or silver on my perovskite solar cells. See more information here: www.nature.com/nphoton/journal/v8/n7/full/nphoton.2014.134.html It truly cost you under $1500 to build? That seems like it might be worth it to me. Would you be willing to answer questions that I have as I try to follow in your footsteps here? I want to compare the efficiency of cells prepared with PVD and cells prepared with a chemical deposition process.
Sure, It actually went together pretty easily but i'd be willing to answer whatever questions you have and try to help you out. I haven't made solar cells with mine yet, that would be pretty interesting to see the difference between PVD and chemical If you need accurate repeatable thicknesses a quartz thickness setup would be needed. Yes It ended up costing around $1500 with everything but on ebay you never know
BenNBuilds Thanks for the quick reply and the tip about the quartz thickness setup. Most of the papers I've read use a scanning electron microscope on a cross section of the cell, which is probably out of my reach until I get access to a real lab. If you wanted to try making some perovskite solar cells you'd need a spin coater and something to get the ITO glass atomically clean. I was looking at this spin coater, but it's back-ordered: www.ebay.com/itm/SCK-200P-Spin-Coater-Kit-/251290334443?pt=LH_DefaultDomain_0&hash=item3a821234eb I plan on using an ultrasonic bath to clean the cells: www.joyfay.com/3-2l-ultrasonic-cleaner-heater-mechanical-110v-220v-100w-40khz-ce-rohs.html?gclid=CjwKEAjwgMieBRCB3bqB94e9lD4SJABW3sTNS5BrFXY77DfmWiqoweN_gebiDHqCOsY8qsvATzuVcxoCmNDw_wcB but the pros use Ultraviolet/Ozone cleaners like this one: www.uvotech.com/uv_ozone_cleaners/compact-uv-ozone-cleaning-system/
If you build a PVD chamber it's pretty easy to throw some wire around it and ignite a plasma inside with a few watts of RF. Intro to plasma cleaning it works pretty good in my chamber and really cleans stuff better than acetone in a sonic cleaner, which I do first anyway to get the larger dust and oils off. A spin coater would be pretty easy to DIY but to get ITO you need a a sputter gun. The stuff to make one is easy to find on mcmaster and I bought an ITO target on ebay for $100. The sputter gun works well with a rectified MOT
BenNBuilds Oh yeah I have seen that vid in the past thanks for the reminder. I was just gonna buy the ITO glass at first here: www.adafruit.com/products/1310

but the pros use Ultraviolet/Ozone cleaners like this one:

If you build a PVD chamber it's pretty easy to throw some wire around it and ignite a plasma inside with a few watts of RF. Intro to plasma cleaning
it works pretty good in my chamber and really cleans stuff better than acetone in a sonic cleaner, which I do first anyway to get the larger dust and oils off.
A spin coater would be pretty easy to DIY but to get ITO you need a a sputter gun. The stuff to make one is easy to find on mcmaster and I bought an ITO target on ebay for $100. The sputter gun works well with a rectified MOT
BenNBuilds Oh yeah I have seen that vid in the past thanks for the reminder. I was just gonna buy the ITO glass at first here: www.adafruit.com/products/1310
