Abstract
Stress in thin films deposited by Reactive Low-Voltage Ion Plating (RLVIP) is studied in air and at room temperature. A multilayer stack, composed of tantalum pentoxide and silicon dioxide
layers, is considered and the interactions layer to layer turn out to have no effect as regards to the final bending. The evolutions of plate bending after annealing show the possibility to reduce the stress as well as the absorption for tantalum pentoxide thin films. Finally, ion implantation, with ions such He+ or Xe+ accelerated at energy in the MeV range, proves to be also a way to vary and reduce the stress in thin films.
