Description
図5は、実施例に係る封止構造を示す概略断面図である。図5に示されるように、主面2aの中央部に窪み51が設けられた第1基板2Aと、当該窪み51に対向する主面4aを有する第2基板4とを、枠状の封止部3によって接着された封止構造101を準備した。この封止構造101の準備方法を以下にて説明する。
フィルム状の接着層12に対して予め大気圧プラズマ処理を施した以外は実施例1と同様の手法により、封止構造を準備した。大気圧プラズマ処理では、まず周波数が10kHzである10kVの交流電圧をヘリウムガスに印加し、当該ヘリウムガスをプラズマ化した。そしてこのプラズマ化したヘリウムを大気中にジェット噴出させ、接着層12の表面に照射した。
封止部3の代わりに、エポキシ樹脂系接着剤(ナガセケムテックス株式会社製XNR5516)を用いて第1基板2Aと第2基板4とを接合し、封止構造を得た。本比較例では、第1基板2Aの主面2aに第1金属層11を形成せず、第2基板4の主面4aに第2金属層13を形成しなかった。したがって本比較例では、第1基板2A及び第2基板4は、硫酸加水に浸漬していない。
実施例1の封止構造101、実施例2の封止構造、及び比較例の封止構造のそれぞれに対して高温高湿試験を行い、各封止構造内に充填された乾燥剤の重量変化を測定した。高温高湿試験では、温度を85℃に設定し、湿度85%に設定した条件下に各封止構造を300時間静置した。
