Ultra-Thin Silicon Wafers

Thin silicon substrates are used in flexible device research, sensors and photovoltaic experiments. Thickness, handling and processing requirements depend on the application.

Thick Silicon Wafers

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

Intrinsic and Undoped Silicon Wafers

Intrinsic and undoped silicon wafers can be selected for high-resistivity research applications. For devices that require an insulating layer beneath the active silicon, compare silicon-on-insulator (SOI) wafers.

Low-Resistivity Silicon Wafers

Low-resistivity, doped silicon wafers are available for applications that require a conductive substrate. For epitaxial research, compare silicon epitaxy substrates and specify the required resistivity range.

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!

What Are Silicon Wafers?

A silicon wafer is a thin, circular slice of crystalline silicon used as a substrate in semiconductor fabrication, microelectronics and materials research. Wafer specifications such as crystal orientation, dopant, resistivity, thickness and surface finish affect which processes it supports. Learn more about silicon wafer materials and applications.


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

How Much Do Silicon Wafers Cost?

Silicon wafer pricing depends on diameter, grade, thickness, resistivity, polishing, quantity and any special processing. Compare silicon wafer options in the online store or request a quote for custom wafer specifications.

Silicon Wafer Properties and Applications

  • 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.
