Description
層間厚みが5μm以下の誘電体層と、卑金属を含む内部電極層とを有する積層セラミック電子部品を製造する方法であって、
誘電体層用ペーストと、卑金属を含む内部電極層用ペーストとを、交互に100層以上配置した積層体を、還元性雰囲気下で焼成し、その後アニール処理する工程と、
該アニール処理後の積層体を、酸素分圧P3が2.9×10−39 Paを超え6.7×10−24 Pa未満の強還元性雰囲気下で、300℃を超え600℃未満の保持温度T3で第1の熱処理をする工程と、
該熱処理後の積層体を、酸素分圧P4が1.9×10−7Paを超え4.1×10−3Pa未満の雰囲気下で、500℃を超え1000℃未満の保持温度T4で第2の熱処理をする工程とを、有する積層セラミック電子部品の製造方法が提供される。
好ましくは、前記T3が、400〜550℃である。
好ましくは、前記P4が、3.5×10−6〜1.1×10−3Paである。
好ましくは、前記T4が、600〜900℃である。
前記ガラス成分原料が、Ba化合物及びCa化合物の一方又は双方と、Si化合物とを有し、
前記添加物成分原料が、Mg化合物と、Mn化合物と、V化合物、W化合物及びMo化合物から選ばれる1種または2種以上と、R(但し、Rは、Y,Sc,Eu,Gd,Dy,Ho,Er,Tm,Yb,Lu及びTbから選ばれる1種又は2種以上)の化合物とを有し、
チタン酸バリウム原料をBaTiO3 に、Ba化合物をBaOに、Ca化合物をCaOに、Si化合物をSiO2 に、Mg化合物をMgOに、Mn化合物をMnOに、V化合物をV2 O5 に、W化合物をWO3 に、Mo化合物をMoOに、Rの化合物をR2 O3 に換算したときに、
BaTiO3 :100モルに対する比率が、
Ba化合物+Ca化合物:0.1〜12モル、
Si化合物:0.1〜12モル、
Mg化合物:3モル以下(但し、0モルを除く)、
Mn化合物:0.5モル以下(但し、0モルを除く)、
V化合物+W化合物+Mo化合物:0.3モル以下(但し、0モルを除く)、
Rの化合物:0.02〜5モルである誘電体層用ペーストを用いる。
なお、本発明において、「保持温度」とは、文字通りの意味の他に、最高温度を意味することもある。
次に、本実施形態に係る積層セラミックコンデンサ1の製造方法の一例を説明する。
チタン酸バリウム原料をBaTiO3 に、Ba化合物をBaOに、Ca化合物をCaOに、Si化合物をSiO2 に換算したとき、
好ましくは、Ba化合物+Ca化合物:0.1〜12モル及びSi化合物:0.1〜12モルであり、より好ましくは、Ba化合物+Ca化合物:0.1〜6モル及びSi化合物:0.1〜6モルである。Ba化合物+Ca化合物の添加量及びSi化合物の添加量が少なすぎると、比較的低温での緻密化が困難であり、しかも温度特性に悪影響を与えることがある。
チタン酸バリウム原料をBaTiO3 に、Mg化合物をMgOに、Mn化合物をMnOに、V化合物をV2 O5 に、W化合物をWO3 に、Mo化合物をMoOに、Rの化合物をR2 O3 に換算したとき、
好ましくは、
Mg化合物:3モル以下(但し、0モルを除く)、
Mn化合物:0.5モル以下(但し、0モルを除く)、
V化合物+W化合物+Mo化合物:0.3モル以下(但し、0モルを除く)、
Rの化合物:0.02〜5モルであり、
より好ましくは、
Mg化合物:0.1〜2.5モル、
Mn化合物:0.25モル以下(但し、0モルを除く)、
V化合物+W化合物+Mo化合物:0.01〜0.1モル、
Rの化合物:1〜3.5モルである。
Mg化合物の添加量が少なすぎると異常粒成長が生じる傾向にあり、多すぎると比誘電率が低下する傾向にある。Mn化合物の添加量が多すぎると比誘電率が低下する傾向にある。V化合物、W化合物及びMo化合物の合計添加量が多すぎると、IRが著しく低下する傾向にある。Rの化合物の添加量が多すぎると焼結性が悪化する傾向にある。
本発明では、アニール処理後に、特定条件下での第1の熱処理を施した後、後述の第2の熱処理を施す点に特徴がある。
これに加え、内部電極層の端部酸化の改善による容量バラツキを改善することができる。
すなわち、上述した第1の熱処理及び第2の熱処理をセットで施すことで、IR温度依存性を劣化させることなく、容量バラツキを改善することができる。

降温温度:室温(20℃)。
得られた焼結体の端面を、外部電極としてCuペーストにて塗布/焼付けを行い、図1の積層セラミックコンデンサ試料を得た。
得られたコンデンサ試料について、同一ロットの30個に対し、基準温度20℃において、デジタルLCRメータ(横河電機社製:YHP4284)にて、周波数1kHz、入力信号レベル(測定電圧)1Vrms/μmの条件下で、静電容量Cを測定し、3σ/x(xは30個の平均)として容量バラツキを算出した。(3σ/x)の値が15以下の場合に容量バラツキが少なく、良好であると判断した。
IR温度依存性(桁落ち)は、得られたサンプルの高温(150℃)における絶縁抵抗IR150 と、室温(20℃)における絶縁抵抗IR20とを測定し、下記式1で示される桁落ちを算出して評価した。評価基準は、−1.50超を良好とした。log(IR150 /IR20) …式1
各温度での絶縁抵抗の測定には、温度可変IR測定器を用い、測定電圧6.3V、電圧印加時間60sで測定した。
これに対し、第1の熱処理に引き続き、第2の熱処理を行うことで、IR温度依存性を劣化させることなく、コンデンサ試料の容量バラツキを改善することができることが認められる。
次に、第2の熱処理を保持温度T4が750℃及び酸素分圧P4が9.5×10−5Paの条件で行うことを前提とした場合に、アニール後の第1の熱処理を行わないと(試料2)、あるいは第1の熱処理における酸素分圧P3及び保持温度T3が低すぎると(試料3)、その後に第2の熱処理を行っても、IR温度依存性を劣化させることなく、コンデンサ試料の容量バラツキを改善することができない。P3及びT3が高すぎても(試料8)、同様である。
これに対し、P3及びT3が適正範囲に制御されている場合には、IR温度依存性を劣化させることなく、コンデンサ試料の容量バラツキを改善することができることが認められる(試料4〜7)。
これに対し、P4及びT4が適正範囲に制御されている場合には、IR温度依存性を劣化させることなく、容量バラツキを改善することができる(試料5,12〜14)。
第1の熱処理のT3の保持時間及び第2の熱処理のT4の保持時間を、ゼロ(キープなし)〜24時間まで変化させた以外は、実施例1の表1に示す試料5と同じ条件で、コンデンサ試料を作製し、同じ評価を行った。その結果、同様の結果が得られた。
第1の熱処理の昇温速度及び第2の熱処理の昇温速度を、300℃/時間、1000℃/時間と変化させた以外は、実施例1の表1に示す試料5と同じ条件で、コンデンサ試料を作製し、同じ評価を行った。その結果、昇温速度:500℃/時間のケースと同様の結果が得られた。
誘電体層の層間厚みと積層数を変化させた以外は、実施例1の表1に示す試料1と同様にして、焼結体を作製し、容量バラツキを測定した。結果を表3に示す。
