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 photolithography 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. Fill out the form and receive an immediate quote.

Recent Silicon Wafer FAQs

What is surface flatness of silicon wafer?

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) silicon wafer?

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.

Do you sell platinised 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? If so, how?

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 wafers 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.

  • Super Thin Silicon used for Solar Application with >45% effiencies
  • Thick Silicon wafers used as substrates for depositing various films on them, like polymer membranes.
  • Intrinsic Silicon wafers that let circuits built on it act very fast. This is also why one uses SOI wafers.
  • Low resisivity Silicon wafers used by laboratories that use Epi growth reactors.
  • Standard substrates used for npn transistor circuits npn transistorand optical applications.
  • Inexpensive Silicon wafers used to make ultra-pure and ultra-clean carrier that do not react  with the organic  sample to be analyzed.
