Turning Silicon Wafers into Computer Chips

What do Researchers Use our Silicon Wafers for?

Some clients use the following Si item #447 76.2mm and Si item #1196 100mm silicon wafers for the fabrication of microfluidic devices.

100mmm and 200mm silicon wafers are used by researchers

"...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.

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.

We carry a large selection of Silicon Wafers with the following specifications:

Thermal oxide wet and dry

Silicon nitride LPCVD and PECVD

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.

What is Silicon Wafer surface flatness?

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

Total Thickness Variation (TTV) <1 um. These are great for making SOI or MEMS!

What is the roughness value (rms) of your Silicon Wafers?

The majority of our Prime Grade wafers have a roughness value Ra<5Å .

What is the definition of silicon wafers?

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.

Can you deposit Platinum (Pt) on silicon wafers?

Yes! We sell Platinised and thin films of almost all the metals! Just let us know the specs and quantity for an immediate quote!

Do you sell one silicon wafer?

Yes! We sell as few as one Silicon wafer. We sell in individual wafer carrier.

How do you clean Si 100 wafer before silicon dioxide is formed for bump production?

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.[1][2][3] 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)

Can you resize Silicon Wafer diameters from 200mm to 100mm?

Yes! We can laser down the wafer so you could get two 100mm from one 200mm wafers including flats!

What is Silicon-Wafer reclaim?

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.

Vicinal  Silicon

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?

Our Quote:

Si Wafer
2", 500um, P type, <100> off to <110> 6 degree SSP

Pricing depends on quantity.

Silicon Anodes to Speed Up Electric Vehicle (EV) Charging

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.
