Description
Summary:In this paper, results of mechanical strength investigations for glass frit bonded components using tensile and micro chevron testing are presented. Specific attention is given to the formation of lead precipitates close to the glass-silicon interface which affects the strength properties and form reliability risks. Results of the accompanying SEM and TEM investigations suggest that the lead precipitation can be understood in terms of a redox reaction involving the oxidation of the Si wafer and can be reduced by appropriate intermediate layers forming a barrier between glass and silicon.
