What it is

The KLA P-7 is a stylus profilometer used for surface metrology and measurement.[5][1]

How it works

The KLA P-7 uses a stylus with a 2 micrometer tip radius and a 60 degree bevel. The P-7 supports step-height measurement from a few nanometers to one millimeter, and it supports scans up to 150 millimeters without stitching.[4][5]

The KLA P-7 supports two-dimensional and three-dimensional measurements, and its measurement set includes step heights, roughness, bow, and stress. The system also uses software for measurement parameters and data processing.[5]

Where it fits in the process flow

The KLA P-7 is used for production and research and development environments. The instrument is suitable for checking thin-film step heights and etched trench depth after fabrication steps that create vertical relief.[5][4]

Applications

The KLA P-7 is used for thin-film step heights, surface roughness, and etched trench depth.[4][5]

The KLA P-7 is used in semiconductors, MEMS, data storage, opto-electronics, and solar technology. The instrument also supports measurements of depth, waviness, flatness, distance, bearing ratio, and radius of curvature.[5]

Why won't it start?

Documented failure modes, common issues, and field considerations.

  • Not ideal for exceptionally soft substrates (as the stylus may damage the sample)
  • Not ideal for step heights over 440 µm (as this will damage the stylus)
  • Not ideal for step heights where the feature width is smaller than 2 µm (as the stylus will not fit into the feature)
