About PSL Calibration Wafer

About PSL Calibration Wafer
PSL particle-coated wafers are used to calibrate and evaluate wafer surface particle inspection equipment, and play an important role in ensuring the detection sensitivity and accuracy of the inspection equipment.
*PSL particles: polystyrene latex particles
We provide wafers coated with the particle size (*1) desired by the customer. These are ideal for semiconductor inspection and measurement applications.
*1: Select from particle sizes provided by our company
Applications
- Inspection equipment calibration
- Defect Detection Test
- Pseudo foreign matter defects
Can be used in combination with our Non-Patterned Wafer Inspection System (WM Series).
