"...to do ini al tests for deep anisotropic etching of diﬀrac on gra ngs. We have to test diﬀerent masking material and etch solu ons with these (silicon) wafers. Expected result will be part of a later PhD thesis. After the planned etching the wafers will be not further used and will be disposed.
Silicon Wafer Items Used
"As a (silicon) substrate for nanoparticle formation in ionic liquids. The nanoparticles are for fuel cell investigations."
Why pay more for SOI wafers when you don't have to?
UniversityWafer, Inc is the leading silicon wafer distributor to universities and research centers internationally.
"The (silicon) wafers have arrived today, and we really pleased with them! Thumbs up to your production crew!"

Free Technical Assiatance on All Substrates!
Super thin Si 100mm P/B (100) 1-10 ohm-cm 25um 2um thin Silicon also available!
We have plenty of silicon wafers at a low price and small quantities of partial cassettes so you can buy less than 25 wafers and as few as one Si wafer.
Sputtered and Evaporated metals
We can custom make wafers in small quantities. We can dice them, thin them to 2um. We have undoped, low doped and highly doped Silicon substrates that are always in stock.
Typical Client Question regarding silicon wafers:
After looking at your online store, I think we might go with your cheapest silicon wafers, product ID 444. I am in a group that is working on a Senior Design Project to create a biobattery. We need a substrate to pattern with photo-lithography and subsequently deposit various precious metals on that will catalyze certain reactions and conduct electricity. If you have any advice on specific types of wafers we will need for such nano electronic devices I would be happy to know. Thanks.
We make nanomaterials in our lab and one approach is using electrical explosion of wires (EEW). We used one of Scott's old Si wafers (doped with B) and broke off a strip of Si that we attached to electrodes in our EEW apparatus. It worked nicely and we are looking to do the same thing with Ge (Germanium Wafer). We need a wafer that is less than 500 microns thick.

We have a large selection of Prime, Test and Mechanical Grade Silicon wafers
1" - 12" Silicon Wafers low doped and highly doped in stock and ready to ship. Examples full and partial silicon wafer cassettes include:
We have Ultra-Flat Silicon with the following spec
Prime Silicon Wafers 100mm P-type /Boron doped <1-0-0> 490-510 micron 0.005-.020 ohm-cm Semi Std Double Side Polished
The majority of our Prime Grade wafers have a roughness value Ra<5Å .
A Si wafer, or substrate, or silicon is grown in a tube from a seed into a long ingot that is then sliced into various thicknesses used in electronics for the fabrication of integrated circuits and in photovoltaics. The wafer serves as the substrate for microelectronic devices built in and over the wafer and undergoes many microfabrication process steps such as doping or ion implantation, etching, deposition of various materials, and photolithographic patterning. Finally the individual microcircuits are separated (dicing) and packaged.
Yes! We sell Platinised and thin films of almost all the metals! Just let us know the specs and quantity for an immediate quote!
Yes! We sell as few as one Silicon wafer. We sell in individual wafer carrier.
The RCA clean is a standard set of wafer cleaning steps which need to be performed before high-temperature processing steps (oxidation, diffusion, CVD) of silicon wafers in semiconductor manufacturing.
Werner Kern developed the basic procedure in 1965 while working for RCA, the Radio Corporation of America. It involves the following chemical processes performed in sequence:
Removal of the organic contaminants (organic clean + particle clean)
Removal of thin oxide layer (oxide strip, optional)
Removal of ionic contamination (ionic clean)
Yes! We can laser down the wafer so you could get two 100mm from one 200mm wafers including flats!
It's when you have a wafer that has thin films or oxide etc on them and we strip and clean them so the wafers can be reused.
Often companies that want to save money or protect their intellectual property will reclaim their wafers.
Si Wafer Quote!
Clients have used the following Si Wafer for the coating research:
We also manufacture thin slice of pure silicon with electronic properties that ranges the full spectrum of specs and diameters from 25.4mm to 300mm with diced substrates available as well.
We can customize boron phosphide for your research of high-power, high-frequency devices as well as laser diodes.
Vicinal silicon crystallography is the plane the position of which varies very little from that of a fundamental plane of the form.
Researcher requested a the following quote:
We are interested in acquiring vicinal Si (100) wafers with a six-degree miscut angle. We would prefer 2" wafers but any larger size is acceptable. We do not have any other doping/thickness requirements. How quickly would we be able to get them if we were to order and what is your pricing for these?
2", 500um, P type, <100> off to <110> 6 degree SSP
Pricing depends on quantity.
Researchers have used the following substrates with great success!
Si Item #809 - 100mm N/P <100> 1-10 ohm-cm 500um SSP Prime
Si Item #783 - 100mm P/B <100> 1-10 ohm-cm 500um SSP Prime Grade
New anode technology that uses a thin film of porous pure silicon could lead to less-expensive lithium-ion batteries for electric vehicles that charge in just a few minutes and provide over 200 mile range. The technology could help increase an EV’s range by 30 percent or more.
Li15Si4 is the new material that combines silicon with lithium. UniversityWafer, Inc. can help researchers source the material for their lab.
