Thermo Fisher Scientific, Portland, Oregon, announces the Thermo Scientific Metrios AX, the world’s first commercially released scanning transmission electron microscope (S/TEM) to use machine learning to automate high-quality data collection. Designed exclusively for the semiconductor industry, the Metrios AX allows lab operators to quickly generate accurate and precise data, while minimizing the need for operator training.
“The Metrios AX was specifically designed to improve failure analysis, process qualification and metrology by helping semiconductor labs easily create automated workflows that improve productivity,” said Glyn Davies, vice president and general manager of semiconductor at Thermo Fisher. “This innovative S/TEM removes the barriers to automation, giving semiconductor manufacturers quick access to the trusted data they need so they can make highly informed decisions expeditiously.”
The Metrios AX enables semiconductor labs to automatically acquire and measure critical dimensions on semiconductor devices during development or in support of manufacturing. Incorporating machine learning into the instrument helps minimize the time needed to develop automated recipes, allowing more productive utilization of the microscope. Built on Thermo Fisher’s ultra-high resolution Spectra platform, the Metrios AX incorporates several advancements that make it easier to automate repetitive jobs, obtain sub-angstrom resolution images with higher contrast, and keep the microscope automatically aligned for peak performance, all at a lower cost-per-sample than traditional S/TEMs.
Machine-learning technology simplifies automation by coordinating all the necessary instructions to identify, align, and image regions of interest in a sample. Smart Automation significantly reduces the time required to create and maintain automated workflow scripts, or “recipes,” while efficiently handling process variability. The enhanced automation enables semiconductor labs to acquire data on new sample jobs in less than four hours. The Metrios AX also features “Smart Alignment” software that automatically adjusts the column alignments, ensuring that the data collected meets stringent metrology accuracy specifications.
The Metrios AX inherits all the features of the Spectra product family, including new high sensitivity Panther S/TEM detector infrastructure and enhanced (SCORR) corrector technology, which together provide industry-leading low dose, high contrast, damage free imaging at sub-angstrom resolution.
