These wafers are designed for non-product applications, such as chamber conditioning, equipment testing, and safeguarding critical tools during maintenance cycles.
The wafers feature a standard diameter of 100±0.3mm (nominal 4 inches) and a thickness of 525±25um, making them compatible with standard processing tools.
These CZ-grown wafers are doped with Boron (P/N type) with a <100> orientation, offering a resistivity range of 0-100 Ω·CM.
The front side is polished to a high-quality finish, while the backside is etched, providing the optimal balance for dummy and test operations.
Since these are standard stocked sizes, orders are processed rapidly and prepared for shipment within our standard lead time. Sourcing options are available from both Asian and Japanese supply chains depending on your requirements.
