As semiconductor device feature sizes shrink and new nanoscale materials are developed, traditional characterization tools used to study local changes within semiconductors and electronic circuits start becoming obsolete. With in situ TEM, you can image systems at atomic resolution to conduct understand working conditions or test the performance of new devices and materials in your lab.

Fusion is an advanced system used to heat and electrically bias samples within an electron microscope.The system is optimized to produce heating up to 1200 °C or electrical biasing without degrading the resolution of the instrument. With Fusion, atomic resolution of heated samples is now possible. This video outlines the Fusion technology as we well as several scientific applications.

Using the Protochips Fusion System in the SEM, we show Schott glass melting at ~620 °C. Its known melting point is 622 °C. This demonstrates the accuracy of the Fusion heating system. For more information on Fusion, visit www.protochips.com/fusion.
This video shows gold nanoparticles at 600 C. The video shows the stability of the Protochips Fusion™ at high temperatures and the ability to resolve dynamic events with sub-Angstrom resolution. The initial video was taken at 1 frame per second, and then sped up to 5 frames per second using video editing software later. The video was taken in the TEAM 0.5 microscope (FEI Titan, 300 kV, Cs aberration correction, monochromator) at Berkeley National Laboratory, Berkeley, California.
This workflow explains the procedure for preparing FIB samples onto a MEMS-based E-chip for in situ TEM. FIB sample preparation can be used to prepare a wide variety of materials for TEM or in situ TEM analysis and is a relatively simple technique to learn.
