UA 3 P 4 Ultra High Accurate 3D

A profilometer is a metrology and inspection tool used to measure surface topography and profile features on processed substrates. Profilometers in semiconductor and microfabrication work are used to characterize height, step structure, surface form, and other three dimensional geometric results of prior process steps.

A profilometer measures the shape of a surface by collecting topographic information across an area or along a trace and converting that information into a height profile or a three dimensional surface map. Profilometers in this class are used to inspect formed structures and quantify differences in elevation created by deposition, etch, patterning, planarization, or bonding related processes.

Metrology and inspection tools of this class are used after a fabrication step has created a surface or structural feature that needs dimensional verification. Profilometer measurements commonly feed process control by checking whether a prior operation produced the intended surface geometry before the substrate moves to the next manufacturing stage.

Profilometers are used for surface topography evaluation, step height checking, and inspection of patterned or structured surfaces in semiconductor and related precision manufacturing. Profilometers of this type are applied where engineers need nonvisual dimensional information about surface relief rather than only planar imaging.
