Abstract :
Barium strontium titanate (BaxSr1-x)TiO3 films are expected to be utilized for microwave integrated circuit devices; therefore, the preparation of highly crystalline BST films has been investigated. In this study, we attempted to prepare (BaxSr1-x)TiO3 films on MgO and sapphire substrates by sputtering under various conditions. It was revealed that BST films could be obtained at lower substrate temperatures on sapphire substrates, and sputtering gases with low oxygen composition were preferred to improve dielectric properties.
