Mechanical Grade Silicon Wafers
We stock mechanical grade silicon ranging from 25.4mm to 450mm. Also known as "Dummy Grade" or "Test Grade," these wafers are cost-effective alternatives for non-critical applications.
Common Applications include:
- Spin Coating: Testing photoresist application uniformity.
- Equipment Testing: Calibrating robotic handling in semiconductor tools.
- Process Setup: Thermal cycling and dummy loads for furnace operations.
Why pay for Prime Grade?
If you do not need tight flatness (TTV) or specific electrical properties, Mechanical Grade wafers can save you up to 60%. Great for university research and training.

Advanced Substrates: SOI (Silicon on Insulator)
We utilize Smart Cut technology to provide substrates for micro-electronics, photonics, and MEMS. An SOI wafer consists of three layers: the handle substrate, the buried oxide layer (BOX), and the device layer.
