How UniversityWafer, Inc. Helps Researchers?

We help researchers purchase silicon wafers and other semiconductor substrates and services. We have the highest-quality silicon wafers in stock and ready to ship. We aslo supply other semiconductor substrates and services including thermal oxide, nitride, thin films, dicing and more.

DOE Researcher Testimonial - SO39212

"I really do appreciate working with you all.  I order from a lot of places, and by far, you all are one of the best I order from!  Thank you!"

We answer the toughest questions for small volumes and large and are trusted across the world for our customer service. We strive to provided the lowest price and welcome price comparisons. We work hard to beat any price!

We provide in stock wafers priced to beat out other companies and with fast delivery. You can buy as few as one wafer. Quality guaranteed! Our substrates are in stock.

We also can quote your custom specs of any kind in small quantities and low price.

Student researchers have use our glass, sapphire, silicon, III-V and II-VI wafers to make devices including PN Junctions and Solar Cells and numerous other applications.

NEWS: Crystalline Silicon Wafer for Fabricating Photonic Structures

Researchers at Stanford University have used UniversityWafer, Inc. 100mm Silicon Item #783 to fabricate photonic structures that control solar absorption & thermal emissions potentially saving energy costs solar panels, electric vehicles, business and residential building.

Compare our prices and save! We ship internationally.

We have a large selection of hard to find wafer specs in partial cassettes, so you don't have to purchase 25! Please ask us for the list.

25.4mm Silicon Wafers

University researchers have been using 1 inch silicon wafers for years, but now there's a low-cost alternative available for the same purposes. This new technology makes it possible to design your own silicon wafers, enabling you to get just what you need at a fraction of the cost. You can select any material from a catalog, then design the surface that best suits your research. With a low-cost solution, you can use 1 inch silicon wafers to conduct research on battery energy storage.

GaN Epitaxy Wafers for UVC LEDs

Gallium Nitride wafers is the substrate needed to fabricate UVC LEDs for use in sterilization equipment. UVC is part of the electromagnetic spectrum. Unlike UV-A and UV-B both which hit the earth and can tan or burn your skin, UV-C never makes it past the protection of our atmosphere.

What is a Wafer?

In semiconductor parlance, a wafer is the same as a substrate. A wafer/substrate is a thin slice of either Silicon (Si) or other material including but limited to, Silicon-on-Insulartor (SOI), Gallium Arsenide (GaAs) and other compound semiconductor wafers.

The thickness of the wafer can range from just a few microns thick to a puck size in the tens of millimeters or even centimeters.
