Description
特許文献2:特開2009-170737号公報
本発明の第一の実施形態に係る電子部品は、図1から図3に示すように、複数(図示の例の場合6層)の内部配線層を備えるようにセラミックシート11,12,13,14,15,16,17を積層した第一積層体10と、セラミックシートの表面に配線層を備えた第二積層体30とを、第一積層体10と第二積層体30の積層方向が互いに直交するように(第一積層体10の配線層と第二積層体30の配線層とが互いに90°の角度をなすように)接合したものである。
本発明の第二の実施形態に係る電子部品は、前記第一実施形態のインダクタと同様に、セラミック積層体の各配線層にインダクタ用導体を備えた第一積層体と、これらのインダクタ用導体をインダクタを形成するように接続する接続導体を備えた積層体とを有するものであるが、前記第一実施形態と異なり、図4から図6に示すように第一積層体40の対向する一対の側面にそれぞれ第二積層体80と第三積層体90を接合し、インダクタが二重螺旋構造を有する。
本発明の第三の実施形態に係る電子部品は、図7から図8に示すように、前記第一および第二実施形態と同様にセラミック積層体の各配線層にインダクタ用導体111,112,113,114,115,116,117を備えた第一積層体100と、これらのインダクタ用導体111~117を接続する接続導体121,122,123,131,132,133を備えた積層体(第二積層体120および第三積層体130)とを有するものであるが、前記実施形態と異なり、各インダクタ用導体111~117が第一積層体100の対向する一対の側面の間に亘って延びる直線状の電極であり、これらの電極を、インダクタを形成するように第二積層体120に設けた接続導体121~123と第三積層体130に設けた接続導体131~133とで接続する。
本発明の第四の実施形態に係る電子部品は、図10に示すように共振器を2段、すなわち、インダクタL1とキャパシタC1からなるLC共振器143と、インダクタL2とキャパシタC2からなるLC共振器144とを入出力端子141,142間に備えることにより通過帯域を形成したバンドパスフィルタである。
本発明に係る電子部品を製造する方法としては、これに限定されるわけではないが、本出願人による先の提案(特願2010-165398)を好ましく適用することが出来る。以下、この方法について図14から図27を参照し、前記第四実施形態のバンドパスフィルタを例にとって簡潔に説明する。
図14に示すようにまず、セラミック材料により形成した未焼成のグリーンシートを用意し、その表面に導電性ペーストを塗布して第一積層体150,160の各配線層に対応した所定の導体パターンを印刷することによりセラミックシート301,302,303,304,305を作製する。これらセラミックシート301~305の各々に印刷する導体パターン311は、作製するチップの数に対応した数だけ縦方向と横方向とにマトリックス状に配列するように形成する。なお、図14(図15から図27についても同様)に示した各導体パターン311は、当該製造方法の概念を示すためのものであって、前記実施形態の導体形状を正確に表すことを意図するものではない。
図20から図21に示すように第三積層スティック413および第四積層スティック423を、それらの配線層(表裏面)が垂直に立つように当該積層スティック413,423の長手方向の周りに90°回転させる。
図26に示すように切断線510(図25も参照)において第三積層シート512を縦方向と横方向とに方眼状(さいの目状)に切断し、図27に示すようにチップ522を得る。その後、個々のチップ522を焼成する。これにより、第一から第五の各積層体150,160,170,180,190のセラミック層が焼結して連続したひとつの焼結体となる。なお、焼成後には、チップ522の外表面に外部電極(端子電極)を適宜形成すれば良い。
