Abstract
Miniaturisation in microelectromechanical systems (MEMS) and continuing advances in fabrication of functional and complex thin film structures approaching the nanoscale has seen adhesion and mechanical stability as key issues. The reliability of thin film-substrate systems when subjected to externally applied stresses is strongly influenced by the intrinsic film properties and the associated interfacial adhesion characteristics. Accordingly, understanding the fracture damage and adhesion performance of thin films to applied stresses is crucial. Using micro-mechanical in-situ tensile experiments it is possible to detect and analyse the critical conditions for cracking and decohesion of the thin film. In this work it will be shown that these types of experiments offer new insights into evaluating mechanical response and interfacial adhesion using a titanium oxide thin film on polycarbonate as the model system. © 2005 Engineers Australia
