|Abstract:||The etching properties of HfO based high-K dielectrics were investigated. The study was carried out by using inductively coupled plasma of Cl 2/HBr/CHF3/CF4/O2. It was The result show that the etching of HfON, HfSiO and HfAlO was strongly dependent on etching properties of each phase in the makeup of the films such as HfO 2 and HfN. It was also found that the fluorine containing plasmas were undesirable for etching of HfO based high-K devices.|
