Quartz Wafer Surface Analyzer

Thickness from frequency, map and 3D

A process analysis instrument for surface-profile mapping through development and small-volume production. CCD locates the wafer frame, thickness is derived from the frequency measured at each point, and the result comes out as an Excel report, a colour map and a 3D surface.

QB-WT-200

2 / 3 / 4 inch wafers

Square wafers up to 100 mm diagonal as well.

Frequency to thickness

Point-by-point measurement mapped to thickness.

0.003 μm flip-side agreement

Re-measured with the wafer flipped: 0.003 μm on average and RMS, 0.01 μm PV.

Map, 3D and Excel

PV, RMS, AVG, SizeX/Y reported directly.
