| Abstract | An acoustic resonator includes a first piezoelectric layer, a second piezoelectric layer, a coupler layer, a first electrode, and a second electrode. The first piezoelectric layer has a first polarity. The second piezoelectric layer has a second polarity opposite to the first polarity. The coupler layer is between the first piezoelectric layer and the second piezoelectric layer. The first electrode is on the first piezoelectric layer opposite to the coupler layer. The second electrode is on the second piezoelectric layer opposite to the coupler layer.
음향 공진기는 제1 압전 층, 제2 압전 층, 결합기 층, 제1 전극 및 제2 전극을 포함한다. 제1 압전 층은 제1 극성을 갖는다. 제2 압전 층은 제1 극성과 반대인 제2 극성을 갖는다. 결합기 층은 제1 압전 층과 제2 압전 층 사이에 있다. 제1 전극은 결합기 층에 대향하는 제1 압전 층 상에 있다. 제2 전극은 결합기 층에 대향하는 제2 압전 층 상에 있다. |
