SILICON WAFERS

Silicon wafers are used as a substrate material in a wide range of applications. They are the building block of modern electronics. WaferPro offers Prime, Test, Monitor, SEMI standard, and customized silicon wafers in all diameters from 2″ to 300mm. Our silicon wafers are made by the most commonly used process called Czochralski (CZ) process.

The Czochralski-technique allows us to make big crystal diameters and lower production cost per wafer. Our manufacturer always makes sure that the silicon wafers are high grade and factory sealed. Our customers come from many industries such as semiconductor, optical, MEMS, sensors, university, equipment, disk drive, aerospace and more.

Customizability

Customizability is our top priority so not only do we offer variable diameter but also fabricate Silicon Wafers with customized specs including SEMI Standard.

 

All you’ll have to do is tell us your desired diameter, thickness, orientation & secondary flat length, and we’ll do the rest for you. Rest assured, as the final product you’ll receive will be of the greatest possible purity and have the final touches of a truly professional machine.

 

WaferPro also provides silicon thermal oxide wafers SIO2 with many thermal oxide options, including wet, dry, and hybrid growth; and thicknesses from 150Å up to 150,000Å.
