Description

The Nova 600 is a "dual beam" system that combines a scanning electron microscope (SEM) with a gallium focused ion beam (Ga-FIB). It can be used to capture high quality images (with sub-10 nm resolution) and perform site-specific etching and material deposition (with sub-50 nm resolution). It is also equipped with an Omniprobe lift-out system for TEM lamella sample preparation. See a full list of training and educational resources for this instrument below.

SEM Applications

• Ultra-High-Resolution Imaging (Immersion Mode)
• High-Resolution Imaging (Field-Free Mode)
• Secondary Electron (SE) & Backscattered Electron (BSE) Imaging
• Everhart-Thornley Detector (ETD) & Through-the-Lens Detector (TLD)
• Platinum deposition via Gas Injection System (GIS)

Ga-FIB Applications

• Directly etch patterns into material
• Cutting & Imaging Cross-Sections
• TEM Lamella Sample Preparation using an Omniprobe for Liftout
