Abstract
Interfacial fatigue crack characterization is challenging for as-deposited thin films due to issues with fixturing and precision application of cyclic loading. A fixtureless and microfabricated test technique is presented to characterize delamination propagation rate as a function of constant amplitude fatigue loading using a novel peel test configuration and magnetic actuation. The test was demonstrated for 1.6 μm thick Cu films on a Si substrate, where interfacial fatigue crack propagation was observed to follow Paris Law behavior.
