Dimension Vx 210 Atomic Force Profiler

An atomic force profiler is a metrology and inspection tool that measures surface topography by scanning a sharp probe across a sample. Atomic force profilers are used to characterize surface features, roughness, step heights, and other nanoscale morphology on wafers and related substrates. Atomic force profilers belong to the inspection and metrology part of semiconductor manufacturing rather than to a patterning or material deposition step.

Atomic force profilers operate by bringing a fine probe very close to the sample surface and tracking probe motion as the surface height changes under the scan path. Atomic force profilers derive a topographic map from the measured interaction between the probe and the surface. Atomic force profilers generally rely on precision motion control, probe positioning, and signal detection to convert local surface variation into a measurement result.

Atomic force profilers are used after process steps that create or modify surface structure, because the tool evaluates the resulting topography rather than forming the structure itself. Atomic force profilers commonly fit around deposition, etch, planarization, clean, and pattern transfer modules where surface texture, profile shape, and local height differences matter to process control. Atomic force profilers are typically used offline or at dedicated metrology points to verify outcomes before later process integration continues.

Atomic force profilers are applied to surface characterization tasks on semiconductor wafers and similar substrates. Atomic force profilers are used for step height measurement, surface roughness evaluation, defect-related topography review, and profile analysis of patterned or blanket films. Atomic force profilers are also used where contact-scale surface detail is important for development work, failure analysis, and process monitoring.
