Abstract:
A wafer-level chip-scale package includes a body, a conductive via passing through the body, a contact bump formed at a lower portion of the body and in electrical connection with a lower end of the conductive via, a piezoelectric substrate directly bonded to an upper end of the conductive via, and a cavity defined between a portion of the body and the piezoelectric substrate.
