Dynamic characterization of the wetting and drying states of DTI (Deep Trench Isolation) structures using high frequency ultrasonic waves, Caractérisation dynamique de l'état de mouillage et de séchage de structures DTI(Deep Trench Isolation) par ondes ultrasonores haute fréquence

Abbas Salhab

In the semiconductor industry, effective wet cleaning of contamination is a critical factor in ensuring good quality of electronic products. The cycle between the wetting and drying processes can create several problems in the high aspect ratio micro / nanoscale structures. In this thesis work, we..., Dans l'industrie des semi-conducteurs, un nettoyage efficace des contaminations par voie humide est un facteur déterminant pour garantir la bonne qualité des produits électroniques. Le cycle entre les processus de mouillage et de séchage peut alors créer plusieurs problèmes dans les structures...
