摘要: A method of manufacturing a Bulk Acoustic Wave device by providing an active layer formed of an electro-mechanical transducer material, providing a first electrode on the active layer, defining a first electrode portion of the device, whereby a remaining portion of the device is defined around the first electrode, providing a stop-layer on the first electrode, depositing a first dielectric layer on the resultant structure, and planarizing the first dielectric layer until the stop-layer on the first electrode is exposed.
