Abstract

Metallic coatings on glass substrates are widely used in various microelectronic components. However, sometimes high residual stress generated in the deposition process or after leads to the loss of adhesion between the coating and the substrate, posing a threat to the reliability of the whole device. In this paper we showed results of our study of Cr and Cu metallizations on glass, which are of technological interest as conductors in the flat panel displays. Stress measurement and nanoindentation techniques are used to find out the stress state and probe the interfacial adhesion properties of the thin metallizations. Ways to increase the practical adhesion of the metallization to ceramic substrates will be discussed.
