"I use the wafers as test objects to verify my eddy-current measurement setup. As they have a well-defined thickness and homogeneous conductivity, they are ideal for my application."
When were 150mm Silicon Wafers Introduced?
Introduced in 1983, 150mm (5.9 inch, usually referred to as "6 inch") wafers can use the CZ or FZ method for ingot growth.

How are Silicon Substrates Used for Eddy-Current Measurements?
Eddy current testing is a nondestructive testing method widely used to examine materials for defects, measure thickness of materials, and inspect conductivity. It's based on the principles of electromagnetic induction.
- Thickness Measurement: One of the primary uses of eddy current measurements on silicon substrates is to measure their thickness.
- Material Defect Analysis: Eddy current testing can also be used to identify defects within the silicon substrate.
- Doping Level and Type Determination: The conductivity of a silicon substrate can be affected by its doping level and type.
What Wafers are Used in Millimeter-Wave Photoconductive Switches?
A university scientist needed help sourcing the correct wafer for their research:
"Our application is millimeter-wave photoconductive switches. We need really low loss silicon for one state, and long carrier lifetime for the other."
UniversityWafer, Inc. Quoted: 150mm Undoped high resistivity silicon >1000 ohm*cm wafers DSP around 500um thick.
Microreactor Array Device
Researchers from University of Arizona used the following 150mm Silicon Wafers for their Microreactor Array Device research: UniversityWafer, Inc. 150mm 675um+/-25um.
