Novel semiconductor device fabrication requires highly accurate imaging and failure analysis to produce improved and optimized fabrication workflows. This means advanced (scanning) transmission electron microscopy (TEM and STEM, or (S)TEM) tools have become a critical component in all leading-edge wafer-fabrication processes.

However, TEM imaging and analysis are highly dependent on the quality of the sample. As a result, sample preparation is a crucial task in fabrication facilities and failure analysis labs. The problem is that conventional methods for ultra-thin (S)TEM sample preparation are challenging and time-consuming, requiring hours, if not days of manual operation by experienced users. The wide range of materials now used in device manufacturing, coupled with the need for site-specific information, only further complicates this process.

Thermo Fisher Scientific offers rapid, accurate, and robust sample preparation tools for (S)TEM imaging on advanced semiconductor designs. Our entire suite of sample preparation instruments allows you to reach atomic scale data faster, easier, and with minimal cost-per-sample. Additionally, Thermo Scientific AutoTEM 5 Software supports fully automated in-situ TEM sample preparation using DualBeam systems. This gives users (of any experience level) the ability to obtain fast, reliable, and repeatable results. Click through to the appropriate product pages below for more information.
