Abstract: Electro-acoustic resonator and method for manufacturing the same An electro-acoustic resonator comprises an acoustic mirror (120) disposed on a carrier substrate (110), a bottom electrode (130) and a piezoelectric layer (140). A structured silicon dioxide flap layer (150) is disposed on the piezoelectric layer (140), both layers having a common contact surface. Direct disposal of the silicon dioxide (150) on the piezoelectric layer (140) increases the quality factor of the resonator and leads to enhanced RF filter performance.

Abstract: A BAW resonator (RN) with reduced lateral modes is provided. The resonator has an active stack of bottom electrode (BE), piezoelectric material (PM) and top electrode (TE) and at least one element of this active stack has a curved side wall (CSW). Two or more curved side walls may be arranged on spheres, on cylinders or prisms with an elliptical footprint with different radii.

Abstract: An electro-acoustic resonator comprises an acoustic mirror (120) disposed on a carrier substrate (110), a bottom electrode (130) and a piezoelectric layer (140). An aluminum seed layer (180) is disposed on the piezoelectric layer and a structured silicon dioxide flap layer (150) is disposed on the aluminum seed layer. The aluminum seed layer (180) increases the quality factor of the resonator and leads to enhanced RF filter performance.

Abstract: Aspects of the present disclosure relate to a shared image sensor. An example device includes a first lens configured to direct light along a first path in the device, a second lens configured to direct light along a second path in the device, an image sensor configured to receive light from a third path in the device, and an optical element configured to direct the light from the first path to the third path during a first mode. The image sensor is configured to receive the light from the first path during the first mode, and the image sensor is configured to receive the light from the second path during a second mode.
