    • Step Height Repeatability
      A step height repeatability of 4 Å, one-sigma or better on samples up to 1 µm tall offers the best measurement performance in the industry.
    • Apex Software
      The Apex software contains advanced filtering, levelling, and analysis functions, controlled with a simple and intuitive interface. Over 40 key parameters are available, including depth, step height, roughness, waviness, slope, flatness, radius of curvature, stress, bearing ratio, distance, volume, and peak count distribution.
    • Productivity Package
      The Productivity Package includes pattern recognition, 1000 sequence sites and a sequence queue. Can be combined with integrated Apex software for filly automated data collection and reporting.
    • 3D Imaging
      3D imaging and viewing of surface topography in photo-realistic, colour-coded, and rotatable 3D or top-down contour maps. Perform comprehensive analysis of scanned features as they appear in 3D and in 2D by examining cross-sections.
    • 2D Stress Analysis
      Stress is measured in 2D using Stoney's equation to calculate the stress of a processing step, such as thin film deposition, by measuring the change in curvature of the substrate.
Specification
  • KLA's P-7 stylus profiler provides advanced surface measurement and analysis capabilities. This mid-range platform is ideal for research and development and production environments offering the best features-to-value of any stylus profiler on the market.

    Repeatability

    The P-7 features industry leading step height repeatability due to superior sensor and scanning stage design

    Steps ≤ 1 µm Steps > 1 µm
    Repeatability1 4 Å 0.10%
    Reproducibility1 15 Å 0.25%

    1. Repeatability and reproducibility are defined as standard deviation of 30 trials using best known methods on a well-defined step height.

    UltraLite® Sensor

    The UltraLite® sensor is a linear variable differential capacitive (LVDC) sensor with the lowest mass, lowest noise, and highest resolution of any sensor available. It is the only sensor technology with constant force control over the entire vertical range.
