High-Resistivity Silicon Wafers

  1. 4" Intrinsic > 10,000 Ohm-cm
  2. 2" Intrinsic > 10,000 Ohm-cm
  3. 8" Intrinsic > 5,000 Ohm-cm
  4. 6" Intrinsic > 20,000 Ohm-cm

We have a large selection of 1" - 12" Silicon Wafers.

We have plenty of partial cassettes so you can buy less than 25 wafers and as few as one wafer.

We carry a large selection of thermal oxide wet and drysilicon 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.

Super Thin Silicon Wafers 

Used for Solar Application with >45% effiencies

Thick Silicon wafers

Used as substrates for depositing various films on them, like polymer membranes.

Intrinsic/Undoped Silicon Wafers 

Let's 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.


"WE have plenty of partial silicon wafers cassetttes available. Below is a short list of requested materials that you can buy as few as one. Also, see below for 0.1-0.5 ohm-cm wafers. Let us know if you can use or if you need us to quote something else."

Client Silicon Wafers Question

Client Question:

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.

Thin Silicon For Solar

We have 100um thick Silicon Wafers that research has shown can be three times more efficient then current solar wafers. Ask for more details by filling out the form today!
