High-Resistivity Silicon Wafers

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 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.

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!

Silicon Wafer Slices in Eletronic Components in Layman's Terms

What are Silicon Wafers?

When pure silicon is sliced into thin circles it becomes a silicon wafer. These sliced wafers come from one pure silicon crystal. When it comes to the manufacturing microelectronic devices silicon wafers are considered to be the go to material.

What are the Applications for Silicon Wafers?

Silicon is widely considered the best material for most electronic devices. The electronics that silicon is commonly found in are, phones, microwaves, sensors, credit card security chips, mp3 players and many other devices. It is possible to apply silicon to all of these different devices through printing circuitry patterns on the wafers.

How are Silicon Wafers Made?

Elemental silicon is refined from sand
Sand is melted and then cools to re-crystallize silicon. This creates a large silicon crystal in a cylinder shape
Thin slices are cut to form silicon wafers
The surface is polished
Circuit patterns are cut and polished into the wafers
When printing is complete the wafers are inspected for issues or flaws
Wafers are cut into chips which is considered dicing. These are a rectangle shape

What is the Cost of a Silicon Wafer?

The cost of a silicon wafer can range from <$1.00 to $50,000. There are many variables that must be considered like, polish, cut, size, purity, orientation and the printing. Visit our store for some price ranges.

Silicon Wafer Fun Facts

Silicon wafers that are being manufactured are made from the purest material on Earth. Silicon has very few flaws and has near perfect purity.
Silicon is transparent when exposed to infrared light.
Polished wafers are used as protection for thermal cameras
Silicon dioxide occurs when silicon is exposed to oxygen. This is the basic material in glass.
