Circuits Assembly Online Magazine - Thermo Fisher Scientific Rolls Out Helios G4 SEM

Helios G4 plasma-focused dual ion beam (FIB) system is designed to de-process and provide ultra-high-resolution scanning electron microscope (SEM) analysis on semiconductor devices.

Can perform failure analysis applications from high-speed delayering to SEM cross-section imaging of devices and TEM sample preparation. Used to expose metallization layers, permitting electrical fault isolation and analysis with nanoprobing tools. Can support de-processing down to 7nm node and offers automated end pointing that stops milling automatically when the metal or via layer of interest is exposed. Reportedly provides up to 10 to 20 times faster milling rates than conventional (Ga+) FIB solutions, permitting larger samples for nanoprobing and TEM imaging, as well as large-area SEM cross-sections, on a range of advanced (2.5D) packaging, LED, display and MEMS.
