Abstract
An acoustic wave device is disclosed. The acoustic wave device can include a substrate, an interdigital transducer electrode disposed on the substrate, and a temperature compensation layer over the interdigital transducer electrode. The IDT electrode includes a lower layer, an upper layer, and a buffer layer disposed between the lower layer and the upper layer. A modulus of elasticity of the buffer layer is less than a modulus of elasticity of the upper layer. The buffer layer is configured to release stress between the lower layer and the upper layer caused due to a difference between a coefficient of thermal expansion of the lower layer and a coefficient of thermal expansion of the upper layer.
