Abstract: A lens includes a lens portion; a multilayer anti-reflective (AR) coating layer, including either one or both of a low refractive index layer and a high refractive index layer, disposed on one surface of the lens portion; and a water-repellent layer, including a water repellent, disposed on one surface of the multilayer AR coating layer. Either one or both of the low refractive index layer and the high refractive index layer are formed of a nitride-based material with a band gap greater than 3.1 eV.

Abstract: A bulk acoustic wave resonator includes a substrate; a central portion including a first portion of a first electrode, a first portion of a piezoelectric layer, and a first portion of a second electrode laminated in order on the substrate; and a reflective region disposed laterally of the central portion and including a second portion of the first electrode, an insertion layer, a second portion of the piezoelectric layer, and a second portion of the second electrode. A side surface of the insertion layer adjacent to the central portion has an inclined surface, the first portion of the second electrode and the second portion of the second electrode are coplanar, and an end of the second electrode overlaps the inclined surface of the insertion layer in the reflective region.
