Instrument Capabilities

The KLA P-7 is a high-precision contact surface profilometer used to quantitatively characterize surface topography and thin-film features. The system measures film thickness, step height, etch depth, and surface roughness by moving a stylus across the sample surface and recording changes in surface height.
The system is currently equipped with a 2.5 µm-radius stylus with a 60° cone angle, providing a balance between measurement sensitivity and the ability to characterize patterned and microfabricated structures.

Key features:

  • Profiles are independent of sample type, allowing characterization of a wide range of materials and substrates
  • Z-axis resolution: 5.7 Å
  • Vertical measurement range: 0–327 µm with three selectable ranges:
    • 0–13 µm
    • 0–65 µm
    • 0–327 µm
  • Variable stylus force: 0.5–50 mg
  • Maximum substrate thickness: 1 inch
  • 6-inch diameter stage for wafer and sample handling
  • Vacuum hold-down for secure positioning of substrates during measurement
  • Motorized leveling for controlled sample alignment
  • Manual sample rotation for measurement orientation and profile positioning
  • 2.5 µm stylus tip radius
  • 60° stylus cone angle
