Résumé

Wetting efficiency of microstructures or nanostructures patterned on Si wafers is a real concern in integrated circuits manufacturing. We present here a high-frequency acoustic method which enables the local determination of the wetting state of a liquid on real DTI and TSV structures. Partial wetting states for non-hydrophobic surfaces or low surface tension liquids are detectable with this method. Filling time of TSV structures has also been measured.
