3、 Application Cases

step height

P-17 can provide measurements of 2D and 3D step heights ranging from nanoscale to 1000 μ m. This enables quantification in etching, sputtering, SIMS， Materials deposited or removed during deposition, spin coating, CMP, and other processes. P-17 has constant force control function, which can dynamically adjust and apply the same micro force regardless of the step height. This ensures good measurement stability and the ability to accurately measure soft materials such as photoresist.

Texture: roughness and waviness

P-17 provides 2D and 3D texture measurement and quantification of sample roughness and waviness. The software filter function divides the measured values into roughness and waviness parts, and calculates parameters such as root mean square (RMS) roughness.

Appearance: Warping and Shape

P-17 can measure the 2D shape or curvature of the surface. This includes measuring wafer warpage, such as during multi-layer deposition in semiconductor or compound semiconductor device production, where layer to layer mismatch is the cause of this warpage. P-17 can also quantify the structural height and curvature radius, including the lens.

Stress: 2D and 3D thin film stress

P-17 is capable of measuring the stress generated during the production of semiconductor or compound semiconductor devices containing multiple process layers. Use a stress chuck to support the sample in a neutral position and accurately measure the sample warpage. Then, by applying the Stoney equation, stress can be calculated using shape changes such as thin film deposition processes. 2D stress is measured through a single scan on a sample with a diameter of up to 200mm, without the need for image stitching. The measurement of 3D stress adopts multiple 2D scans and combines the rotation of the θ platform between scans to measure the entire sample surface.

Defect re inspection

Defect review is used to measure the morphology of defects such as scratch depth. Defect detection equipment identifies defects and writes their location coordinates into KLARF files. The 'Defect Re inspection' function reads KLARF files, aligns samples, and allows users to select defects for 2D or 3D measurement.
