Stylus and Optical Profilometry Webinars

Stylus Profiling Metrology for Soft Matter: Film Thickness and Depth for Flexible Electronic and Microfluidic Devices

Learn more about advanced stylus profiler techniques as Samuel Lesko, Director of Technology and Application Development, Bruker, demonstrates how to collect accurate and repeatable thickness and depth measurements of fragile thin film surfaces

Explore the most innovative capabilities of advanced stylus profilers.

This webinar focuses on how advanced stylus profiler techniques provide effective thickness metrology for fragile thin film surfaces, allowing researchers to both quantify progress and optimize materials and products.

Viewers can expect to gain new insight into:

  • Why advanced stylus profiler techniques provide an optimal thickness metrology solution for thin films;
  • The benefits and advantages of using advanced surface profilometry for thin film analysis; and
  • The range of nanometer- to millimeter-scale thickness metrology applications made possible by advanced surface profiler techniques and instrumentation.

Controlling the Thickness Profile of Thin Films with Advanced Stylus Profilometry

Driven by automation for production, inter-connectivity demands and energy harvesting, Internet of Things (IoT) and green energy solutions are booming. Researchers from both academia and industries actively seek new processes as well as novel materials to develop light and low-cost flexible electronics, or self-power driven and recyclable sensors. Recent innovative devices notably contain stacks of multi-layer thin films with new alloy organic and/or intermetallic materials that are extremely fragile.

By its principle, stylus profiling already ensures unbiased topography even with transparent layers or a different refractive index.

The presentation showcases how advanced stylus profiling further extends to fragile surfaces such as PEDOT:PSS photovoltaic materials, PDMS microfluidic channels or amorphous-indium-gallium-zinc-oxide (IGZO) transistors. A successful solution relies on precise and low controlled force keeping topography unchanged while retaining sub-nanometer repeatability. Through these attributes, the DektakXT stylus profiler opens a wider range of applications for thickness metrology, from nanometers to millimeters.
