Surface acoustic wave device and its preparation

Abstract

(57)【要約】 【目的】 特に困難な方法によることなく、弾性表面波 素子の機能面上に所定の振動空間を確保しつつ、弾性表 面波素子の機能面の封止性能を向上させ、信頼性を向上 させる。 【構成】 弾性表面波素子3を、くし歯状電極2が形成 された機能面3aを外部取出電極8が配設された基板5 に対向させ、該くし歯状電極2及び表面波が伝搬する表 面波伝搬路4を囲む位置に配設された弾性材料からなる 環状部材10を介して基板5上に載置し、弾性表面波素 子3を押圧して環状部材10を弾性表面波素子3及び基 板5に密着させた状態で、接合部材6により弾性表面波 素子3を基板5に固定するとともに、くし歯状電極2と 外部取出電極8とを電気的に接続する。
PURPOSE:To upgrade the seal performance for the functional surface of a surface acoustic wave device and to upgrade the reliability of the surface acoustic wave device by securing a predetermined oscillation space on the functional surface of the surface acoustic wave device without using a particularly complicate fabrication method. CONSTITUTION:In a surface acoustic wave device 3, a functional surface 3a where a tandem type electrode 2 is prepared is mounted opposite to a substrate 5 where an external lead-out electrode 8 is disposed. The surface acoustic wave device 3 is mounted on the substrate 5 via a ring member 10 made of elastic material placed at a position surrounding the tandem type electrode 2 and a surface acoustic wave path 4 through which surface acoustic wave passes. While pressing the surface acoustic wave device 3 to the substrate 5 to make the ring member 10 stick close to the surface acoustic wave device 3 and the substrate 5, the surface acoustic wave device 3 is fixed to the substrate 5 using a connecting member 6 and the tandem type electrode 2 and an external lead-out electrode 8 are electrically connected.
