Along with the improvement in performance of mobile phones and the like, higher performance is also required for filters using surface acoustic wave elements.

For this reason, it is necessary to reduce the temperature coefficient of the frequency change.

- the degree of orientation of the ceramic on the polished surface is 50% or more, and the aspect ratio of the crystal grains constituting the support substrate is 5.0 or less.
- the present inventor has studied to form a support substrate for a composite substrate with ceramics that have high strength and are less likely to crack.
- ordinary ceramics have a polycrystalline structure, it is difficult to improve the flatness of the surface after single crystal polishing to a high degree, and the surface flatness is impaired by grain removal during processing.
- the present inventor has conceived of applying oriented ceramics to a support substrate for a composite substrate.
- Oriented ceramics are controlled so that the crystal particles constituting the ceramics are oriented in a predetermined direction. That is, it has been found that by aligning the bonding surface (polishing surface) of the support substrate, surface accuracy comparable to that of a single crystal can be realized at the time of polishing, and cracks do not occur, and the present invention has been achieved. As a result, the productivity of the composite substrate can be remarkably improved, so that the industrial applicability is extremely large.

Abstract
Description
周波数温度特性が良好な弾性波素子を作製する等の目的で、圧電材料等の機能性基板と低熱膨張を有する材料の支持基板とを貼り合わせた複合基板を利用することが知られている(特許文献1)。
前記セラミックスの研磨面における配向度が50%以上であり、支持基板を構成する結晶粒のアスペクト比が5.0以下であることを特徴とする。
本発明では、複合基板用の支持基板として、特定の結晶面が配向したセラミックスを用いる。これにより、単結晶に匹敵する良好な加工面の精度を確保できると共に、単結晶の加工時に起こりやすい割れを防止することが可能となる。
本発明によって提供可能な複合基板は、支持基板、および支持基板の研磨面に対して直接または接合層を介して接合されている機能性層であって、半導体、圧電体または誘電体からなる機能性層を有する。
(1) 自立可能な機能性基板を支持基板に対して接合した後、機能性基板を加工せずに用いる。
(2) 自立可能な機能性基板を支持基板に対して接合した後、機能性基板の厚さを薄くする加工を行う。こうした加工としては、研磨、研削、一部剥離等がある。
(3) (2)のうち、自立可能な機能性基板を支持基板に対して接合した後、機能性基板の厚さを薄くする加工を行うことによって、厚さが自立不可能な厚さ(例:1μm以下)にまで低減して薄層とする。こうした加工としては、研磨、研削、一部剥離等がある。
加速度センサ、焦電センサ、超音波センサ、電界センサ、温度センサ、ガスセンサ、ノッキングセンサ、ヨーレートセンサ、エアバックセンサ、圧電ジャイロセンサ等の各種センサ、圧電トランス等のエネルギー変換素子、圧電アクチュエータ、超音波モータ、レゾネータ等の低損失アクチュエータ又は低損失レゾネータ、キャパシタ、バイモルフ圧電素子、振動ピックアップ、圧電マイクロホン、圧電点火素子、ソナー、圧電ブザー、圧電スピーカ、発振子、フィルタ、誘電素子、マイクロ波誘電素子、熱電変換素子、焦電素子、プロジェクター、高周波デバイス、高性能レーザー、パワーデバイス、発光素子、レーザー、受光素子、太陽電池、アンテナ切り替え用スイッチ
本発明の支持基板および複合基板の好適な製造プロセスについて例示する。
まず、図4(a)に示すように、配向性セラミックスからなるブランク基板12を準備する。ブランク基板12の表面12a、底面12bは、研削面であってよく、また焼成面(アズファイアー面)であってよい。
具体的には、まず特定の結晶面が露出した板状の粒子からなる原料粉末を準備する。例えば、市販の粉末(例:キンセイマテック製セラフ(Al2O3))を使用しても良いし、他の公知の方法により作製しても良い。
又、配向性セラミックスは、例えば特許文献5に記載のような、磁場を用いた方法でも製造できる。
例えば図4(a)に示すようなブランク基板12の表面12aを研磨加工することによって、図4(b)に示す基材1を得る。5は研磨面であり、1bは未研磨の底面である。次いで、研磨面5を精密研磨加工することによって、各結晶粒子が平面に沿って削られ、それぞれ平坦面を有する、研磨された結晶粒子が表面に露出することになる。この研磨された結晶粒子の表面は平滑となっている。このようにして支持基板11を得る。15は研磨面であり、機能性基板との接合に供する。11bは底面である。
すなわち、金属定盤(Sn、Cu)上に、ダイヤモンドスラリー(平均粒径0.5~3μm)を滴下し、定盤を回転させる。基材の表面を金属定盤と接触するように置き、圧力を加えながら研磨する。
支持基板と機能性層との接合に用いられる技術としては、特に限定される訳ではないが、例えば表面活性化による直接接合や、接着層を用いた基板接合技術が用いられる。
接着層の例としては、樹脂による接着の他に、SiO2、Al2O3、Si3N4が用いられる。
接着剤層の形成方法は限定されないが、印刷、スピンコーティングを例示できる。
ZnOの板状一次粒子は以下の方法にて作製した。
関東化学製硝酸亜鉛六水和物を用い、濃度0.1MのZn(NO3)2水溶液を作製した。又、シグマアルドリッチ製水酸化ナトリウムを用い、濃度0.1MのNaOH水溶液を作製した。NaOH水溶液に対し、Zn(NO3)2水溶液を体積比1:1で混合し、攪拌しながら80℃で6時間保持し、沈殿物を得た。沈殿物をイオン交換水で3回洗浄した後、乾燥することで、板状のZnO一次粒子が凝集した球状の二次粒子を得た。
φ2mmのZrO2製ボールを用い、エタノールを溶媒として、3hrのボールミル粉砕処理を行うことにより、ZnO二次粒子を平均粒径0.6μmの板状一次粒子へ粉砕した。
接合面15を濃度0.3Mの硝酸にて10秒間エッチングを行い、粒界を明確化した後、走査電子顕微鏡にて画像を撮影した。視野範囲は、視野範囲内で平行な直線を3本引いた場合に、いずれの直線も10個から30個の粒子と交わるような直線が引けるような視野範囲とした。前記3本の直線において、直線が交わる全ての粒子に対し、個々の粒子の内側の線分の長さを平均したものに1.5を乗じた値を接合面の平均粒径とした。
支持基板から約10mm角の試料を切り出し、接合面と垂直な面を研磨し、濃度0.3Mの硝酸にて10秒間エッチングを行った後、走査電子顕微鏡にて画像を撮影した。視野範囲は、接合面に平行な直線を3本引いた場合に、いずれの直線も10個から30個の粒子と交わるような直線が引けるような視野範囲とした。接合面に平行に引いた3本の直線において、直線が交わる全ての粒子に対し、個々の粒子の内側の線分の長さを平均したものをa1とし、同様に、接合面に垂直に引いた3本の直線において、直線が交わる全ての粒子に対し、個々の粒子の内側の線分の長さを平均したものa2とし、a1/a2をアスペクト比とした。
実施例1において、スラリー粘度が24000cPとなるよう、分散媒の量を少なくした。又、焼成温度を1400℃とした。その他は実験例1と同様とした。この結果、支持基板の(100)配向度は0.83に上昇した。その他の指標も表1に示した。
実施例1において、スラリー粘度が42000cPとなるように、分散媒の量を少なくした。又、焼成温度を1450℃とした。その他は実験例1と同様とした。この結果、(100)配向度は0.90に上昇した。その他の指標も表1に示す。
硫酸亜鉛七水和物(高純度化学研究所製)1730gとグルコン酸ナトリウム(和光純薬工業製)4.5gをイオン交換水3000gに溶解した。この溶液をビーカーに入れ、マグネットスターラーで攪拌しながら90℃に加熱した。この溶液を90℃に保持し且つ攪拌しながら、25%アンモニウム水490gをマイクロチューブポンプにて滴下した。滴下終了後、90℃にて攪拌しながら4時間保持した後、静置した。沈殿物をろ過により分離し、更にイオン交換水による洗浄を3回行い、乾燥して白色粉末状の酸化亜鉛前駆物質を得た。得られた酸化亜鉛前駆物質のうち100gをジルコニア製のセッターに載置し、電気炉にて大気中で仮焼することにより、65gの板状多孔質酸化亜鉛粉末を得た。仮焼時の温度スケジュールは、室温から900℃まで昇温速度100℃/hにて昇温した後、900℃で30分間保持し、自然放冷とした。得られた板状酸化亜鉛粉末をZrO2製ボールを用い、ボールミルにて平均粒径1.0μmまで粉砕した。
その後の工程は、実施例1と同様とした。
原料として、キンセイマテック製板状Al2O3(グレード00610)を用い、実施例1と同様にして、厚さ20μmのテープを50枚積層したテープ積層体を作製した。実施例1と同様にして脱脂を行った後、黒鉛製の型を用い、ホットプレスにて窒素中1700℃×4hの条件で焼結体を作製した。その後、実施例1と同様に接合面を加工し、支持基板を作製した。
市販のZnO粉末(正同化学製、酸化亜鉛1種、平均粒径0.6μm)を用い、実施例1と同様の方法により支持基板を作製した。
ボールミルでの粉砕後の平均粒径を3.0μmとした。これ以外は実施例4と同様の方法により、支持基板を作製した。
