Description
特に本発明の厚膜抵抗体は、1kΩ/□以上の中抵抗域〜高抵抗域の抵抗体、とりわけ100kΩ/□以上の高抵抗域の抵抗体として極めて有用である。
本発明におけるルテニウム系導電性粒子としては、二酸化ルテニウム(RuO2)を50質量%以上含むことが好ましく、二酸化ルテニウム(RuO2)のみからなるものが更に好ましい。これにより本発明の抵抗組成物は、高温で焼成した後も、安定な導電ネットワークがより容易に形成され、ばらつきが小さく、高抵抗域においても良好な抵抗特性が得られ、その他の電気特性及びプロセス安定性の良好な厚膜抵抗体を得ることができる。
本発明においてガラスフリットとしては、ガラスフリット及び二酸化ルテニウムの混合物の焼成物が1kΩ/□〜1MΩ/□の範囲の値をとるとき、前記焼成物の抵抗温度係数(TCR)がプラスの範囲を示すようなガラスフリットを用いる。
本発明者等は、このような特性のガラスフリットを用いた場合に、ルテニウム系導電性粒子との配合比率を調整したり、後述する無機添加剤を適宜加える等によって、100kΩ/□以上の高抵抗域においてもTCRを小さくすることができることを見出した。例えば本発明の厚膜抵抗体は、100Ω/□〜10MΩ/□の広い抵抗域において、TCRを±100ppm/℃以下にコントロールすることができる。
Tg≦(焼成温度−200)〔℃〕・・・式(1)
また、ガラスフリットの平均粒径D50は5μm以下であることが好ましい。D50が5μm以下であることにより高抵抗域での抵抗値の調整が容易になるが、D50が小さすぎると抵抗体にボイドが発生しやすくなる傾向がある。特に好ましいD50の範囲は0.5〜3μmである。
本発明の厚膜抵抗体を形成する抵抗組成物は、上述した無機成分の他、機能性フィラー(以下、単にフィラーと記すこともある)を含むことが好ましい。
また、本発明においては厚膜抵抗体を構成するガラス成分については、ガラスフリットに由来するガラス成分を「第1のガラス成分」といい、ガラス粒子に由来するガラス成分を「第2のガラス成分」ということもある。
Tg’≧(焼成温度−150)〔℃〕・・・式(2)
本発明に係る抵抗組成物には、本発明の効果を損なわない範囲であれば、TCR、電流雑音、ESD特性、STOL等の抵抗特性の改善や調整の目的で一般的に使用される種々の無機添加剤、例えばNb2O5、Ta2O5、TiO2、CuO、MnO2、ZnO、ZrO2、La2O3、Al2O3、V2O5、ガラス(以下添加ガラスという。なお、「添加ガラス」は、前記の第1のガラス成分、第2のガラス成分とは異なる別のガラス成分である。)等を単独で又は組み合わせて添加してもよい。このような添加剤を配合することにより、広い抵抗値範囲に亘ってより優れた特性の抵抗体を製造することができる。添加量は、その使用目的に応じて適宜調整されるが、例えばNb2O5等の金属酸化物系の添加剤の場合は、一般的には、抵抗組成物中の無機固形分の合計100質量部に対して合計で0.1〜10質量部程度である。また添加ガラスを添加する場合は、10質量部を超えて添加する場合もある。
本発明においてルテニウム系導電性粒子、ガラスフリットは、必要に応じて配合される機能性フィラーや添加剤と共に有機ビヒクルと混合されることにより、スクリーン印刷等の抵抗組成物を適用する方法に適したレオロジーを備えるペースト状、塗料状、又はインク状の抵抗組成物となる。
本発明における抵抗組成物は常法に従って、ルテニウム系導電性粒子、ガラスフリット及び必要に応じて配合される機能性フィラーや添加剤と共に、有機ビヒクルと混合・混練され、均一に分散させることによって製造されるが、本発明において組成物はペースト状に限られるものではなく、塗料状またはインク状でも良い。
本発明における抵抗組成物は常法に従ってアルミナ基板、ガラスセラミック基板等の絶縁性基板や積層電子部品等の被印刷物上に、印刷法等により所定の形状に印刷/塗布され、乾燥後、例えば600〜900℃程度の高温で焼成される。このようにして形成された厚膜抵抗体には、通常オーバーコートガラスを焼付けることにより保護被膜が形成され、必要に応じてレーザートリミング等により抵抗値の調整が行われる。
本発明の抵抗組成物はこれに適したものであり、本発明の抵抗組成物の2種以上をセットで提供することにより、使用者において適宜複数の抵抗組成物を配合して所望の抵抗値を有する抵抗体を作製することが可能な抵抗組成物を調製することができる、これにより、類似した組成の複数の抵抗組成物によって広い範囲の抵抗領域をカバーすることができる。

なお、表4において、ノイズに関してオーバーレンジのため、測定が困難なものについては測定を省略し、表中に“−”で記した。
また各ペースト毎に目標値として設定した抵抗値Rsについても、参考程度に表4に併記した。
本実施例は抵抗組成物が機能性フィラーを含有しない場合についての実施例である。
