FSM 127

• A visible light imaging Michelson Low Coherence Interferometer
• Measures Flatness and Nano-Topography on Die-level
• Measurement area
• 40mm x 30 mm
• Uses interference patterns to determine the surface profile.

Localized Stress Measurement

Inputs to stress measurement w/ FSM 127 system

• Local surface topography
• Local wafer thickness (FSM 413 Echoprobe)
• Local film thickness for most of conductive and insulating films (FSM Thin Film Probe or 4 point probe)

Output

• Local stress tensor components
• No third party input required
