Nanomechanical Testing

In Situ SEM Nanomechanics with Bruker’s PicoIndenter

Discover how researchers are using the latest in-situ nanomechanics technology at cryogenic temperatures and for semiconductor devices

See what experts are doing with in-situ SEM nanomechanical testing 

Bruker’s in-situ SEM PicoIndenters enable unique insight into material deformation behavior. The latest addition to the PicoIndenter product portfolio is PI 89, which introduces ease-of-use upgrades and a streamlined design.

This webinar contains four main segments:

  1. Material Properties at Cryogenic Temperatures, a guest presentation by Dr. Peter Hosemann (UC Berkeley)
  2. Introduction to the PI 89 SEM PicoIndenter, presented by Dr. Sanjit Bhowmick (Bruker)
  3. Demonstration of PI 89, presented by Dr. Eric Hintsala (Bruker)
  4. Mechanical Stability of Advanced Nano-Interconnects, a guest presentation by Dr. Kris Vanstreels (imec)

Webinar Summary

In-situ nanomechanical testing inside a scanning electron microscope (SEM) provides unique insight into material dynamics at small length scales. This webinar is a wide-ranging overview of SEM PicoIndenter topics, from introducing the newest Bruker tool to cryogenic testing being conducted in academia and semiconductor device testing at an industry lab.

After a brief introduction to the webinar, Dr. Peter Hosemann presents on his work investigating material properties at cryogenic temperatures. His interests lie in addressing, fundamentally, why and how materials change their properties at different temperatures. Dr. Hosemann discusses the relevant literature on nanomechanical testing at cryogenic temperatures and shows results correlating electron backscatter diffraction and mechanical testing data for solder joints and ultrafine-grained (UFG) copper.

Bruker nanomechanics expert Dr. Sanjit Bhowmick then discusses the design and capabilities of Bruker’s Hysitron PI 89 SEM PicoIndenter, and Dr. Eric Hintsala follows with a detailed demonstration of the instrument. This demonstration includes pictures and videos of hardware elements and plots and descriptions of experimental data from high-temperature testing.

Dr. Kris Vanstreels closes with an in-depth discussion of back end of line (BEOL) strength testing and benchmarking chip-package interaction (CPI) integrity of nano-interconnects. A PI 88 SEM PicoIndenter was used in several modes for the BEOL strength testing work: indentation, compression, and bending. For the CPI investigation, a wedge indenter was used to induce and analyze thin film delamination.
