Description
弾性波共振器100の製造方法について説明する。支持基板10上に絶縁層11をCVD(Chemical Vapor Deposition)法を用いて成膜する。絶縁層11上に圧電基板を表面活性化法を用いて接合させた後、圧電基板をCMP(Chemical Mechanical Polishing)を用いて薄膜化させて圧電層12を形成する。圧電層12上にIDT22及び反射器24を形成する。
絶縁層11の厚さT1と圧電層12の厚さT2について説明する。図2は、弾性波を説明する断面図である。図2のように、IDT22の電極指15は弾性波50を励振する。なお、図中の弾性波50は変位のイメージを示しており実際の弾性波の変位とは異なる。圧電層12が回転YカットX伝搬タンタル酸リチウム層である場合、IDT22は主にSH(Shear Horizontal)波を励振する。SH波は圧電層12の表面に平行で且つSH波の伝搬方向に直交方向に変位する波である。弾性波共振器の周波数温度係数を小さくするには、絶縁層11内に弾性表面波の変位が分布していることが求められる。
圧電層12のカット角を変え、共振周波数fr及び***振周波数faの周波数温度係数(TCF)と電気機械結合係数(k2)を計算したシミュレーションについて説明する。シミュレーションは図1(a)及び図1(b)に示した構造を用いて以下の条件にて行った。
支持基板10:サファイア基板
絶縁層11:厚さ600nm(0.4λ)の二酸化シリコン層
圧電層12:厚さ600nm(0.4λ)の回転YカットX伝搬タンタル酸リチウム層
