High Precision, High-Resolution Thin Film Failure Analysis

Fracture toughness is an indicator of a material’s ability to resist crack propagation, regardless of its size or shape and the stress applied to the crack itself. Precise fracture toughness measurement is increasingly important in industrial applications because of the trend towards thinner, stronger films; high strength thin film structure materials become more fragile with increasing strength

With the continual decrease of material thickness and increase of structural complexities, accurately measuring thin film fracture toughness has become a major focus of—and challenge to—manufacturers' failure analysis processes.

This webinar addresses and proposes practical solutions for the challenges manufacturers face—including film thickness, interface limitations, and crack length—when measuring thin film cohesion in various applications.
