Silicon substrate integration of BST based tunable TFBARs using all-dielectric SiO2/AlN Bragg reflectors
Paper in proceeding, 2010
Integration possibilities of BaxSr1-xTiO3 (BST) based tunable Thin Film Bulk Acoustic Wave Resonators (TFBAR) using all-dielectric SiO2/AlN Bragg reflectors deposited on a high resistivity silicon substrate are considered. SiO2/AlN reflectors withstand the high deposition temperature (>600C) of the BST films opening up possibilities for heterogeneous integration of complex microwave circuits. © 2010 IEEE.
