Description
本出願は、2017年3月27日出願の日本出願第2017-060774号に基づく優先権を主張し、上記日本出願に記載された全ての記載内容を援用するものである。
従来の積層体においては、圧電体基板とセラミック基板との結合力が不十分となる場合がある。そこで、本開示は、圧電体基板とセラミック基板とが十分な結合力で結合した積層体、および当該積層体を含むSAWデバイスを提供することを目的の1つとする。
本開示の積層体によれば、圧電体基板とセラミック基板とが十分な結合力で結合した積層体を提供することができる。
最初に本願発明の実施態様を列記して説明する。本願の積層体は、多結晶セラミックから構成され、支持主面を有するセラミック基板と、支持主面に対して結合主面においてファンデルワールス力により結合され、圧電体からなる圧電体基板と、を備える。セラミック基板は、支持主面を含むように形成される支持主面アモルファス層を含む。圧電体基板は、結合主面を含むように形成される結合主面アモルファス層を含む。そして、支持主面アモルファス層の厚みは、結合主面アモルファス層の厚みよりも小さい。
次に、本発明にかかる積層体の一実施の形態を、以下に図面を参照しつつ説明する。なお、以下の図面において同一または相当する部分には同一の参照番号を付しその説明は繰返さない。
