Improvement of adhesion and interfacial diffusion behavior in Cu/glass structures using OsOx layers for microelectromechanical systems
Thin OsO2 layer functioned as an effective adhesion layer between Cu and glass. Annealing Ni/OsO2/glass stack improved the adhesion in Cu/Ni/OsO2/glass structures. Intermixing layer formed at the metal/glass interface results in excellent adhesion. Intermixing layer consisted of Cu, Ni, Os, O, and Si.
