The deposition and wet etching of Mg-doped ZnO films and their applications for solidly mounted resonators

Abstract

In this report, a solidly mounted resonator (SMR), consisting of an Au electrode, Mg-doped ZnO (MgXZn1−XO) piezoelectric film and Bragg acoustic reflector, was fabricated on a Si substrate by radio frequency (RF) magnetron sputtering.
