Thermo Fisher Announces Machine Learning S/TEM


Generates repeatable, high-quality semiconductor analysis to accelerate device development and maximise yields

At the International Symposium for Testing and Failure Analysis (ISTFA) 2019, Thermo Fisher Scientific has announced the world's first commercially released scanning transmission electron microscope (S/TEM) to use machine learning to automate high-quality data collection.

Designed for the semiconductor industry, the Thermo Scientific Metrios AX, allows lab operators to quickly generate accurate and precise data, while minimising the need for operator training.

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 minimise the time needed to develop automated recipes, allowing more productive utilISation of the microscope, according to the company.

Built on Thermo Fisher's ultra-high resolution Spectra platform, the Metrios AX is said to be incorporate 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.

“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 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.
