What is Surface Metrology?

The surface metrology techniques we utilize extract topographical information from a surface. Utilizing our expertise with state-of-the-art optical profilers, we have the capability of analyzing complex surfaces and geometries. Our optical techniques provide both 2-D and 3-D surface characterization. Unlike stylus profilometers, our surface profilers are non-contact so samples remain undamaged and intact.

Optical Profilometry is ideal for imaging and measuring step-heights, surface roughness, and feature volume with a high degree of accuracy.

This technology is ideal for analyzing complex surfaces such as:

  • LED patterned/etched substrates
  • Photoresist and stacked multilayer structures
  • Transparent surfaces including glass
  • Patterned sapphire substrates (PSS) bump diameter, height and pitch analysis
  • Microfluidics devices
  • High aspect ratio samples such as microneedles

Method Attributes:

  • Non-destructive
  • 3D surface topography & surface roughness
  • Surface wear, scratch, and corrosion
  • True color measurements

3-D Measurements

Optical profilometry is ideal for many applications and sample types because it accommodates many sample geometries. Our services use either a confocal-like pattern projection technique or white light interferometry depending on the sample and investigation.

  • Step height and dimensional measurement
  • Characterizing wear and friction of mechanical parts
  • Determining consistency of solder bump heights, e.g. on flip chips and other advanced packaging
  • Correlating roughness measurements with materials properties, e.g. adhesion, corrosion, appearance
  • Measuring the radius of curvature of microfluidic channels, optics, etc.
  • Assessing bow on coated/processed wafers, e.g. MEMS fabrication
  • Quantifying thickness of continuous, transparent films e.g. microfluidics
  • High-throughput screening of multiple features on a die or wafer
