Description
(電気素子内蔵型多層基板100)
図1を参照して、本実施の形態における電気素子内蔵型多層基板100について説明する。図1は、電気素子内蔵型多層基板100を示す断面図である。電気素子内蔵型多層基板100は、多層基板10、能動素子20(電気素子)、受動素子24、および摺動部材30を備える。
図5を参照して、電気素子内蔵型多層基板100(図1参照)の製造方法においては、まず、基材層10A〜10G、表面21(主表面)を有する能動素子20(電気素子)、および摺動部材30が準備される。
電気素子内蔵型多層基板100においては、能動素子20の表面21と基材層10Cとの間に、摺動部材30が設けられる。能動素子20の表面21と摺動部材30との接触面は非接着面であるので、能動素子20の表面21と基材層10Cとの間における摺動が実現される。
(第1変形例)
図6を参照して、実施の形態1の第1変形例について説明する。基材層10Dと能動素子20の側面25との間には、間隙部10Sが設けられている。摺動部材30としての金属箔が能動素子20の表面21よりも大きく形成される場合、基材層10A〜10Gの積層および圧着時においては、この金属箔は実質的に形状が変化しない。間隙部10Sは、基材層10A〜10Gに対する加熱時において、能動素子20の側面25に軟化および流動する基材層10C〜10Eの量が、この金属箔の作用によって少なくなることにより形成されることができる。
図7は、実施の形態1の第2変形例における電気素子内蔵型多層基板に用いられる摺動部材30Aを多層基板の積層方向から見た平面図である。図8は、図7中のVIII−VIII線に沿った矢視断面図である。
図9は、実施の形態1の第3変形例における電気素子内蔵型多層基板に用いられる摺動部材30Bを多層基板の積層方向から見た平面図である。図10は、図9中のX−X線に沿った矢視断面図である。
(電気素子内蔵型多層基板100A)
図11を参照して、本実施の形態における電気素子内蔵型多層基板100Aについて説明する。図11は、電気素子内蔵型多層基板100Aを示す断面図である。電気素子内蔵型多層基板100Aは、多層基板10、能動素子20、受動素子24、他の能動素子28、摺動部材30、および補助部材36を備える。他の能動素子28は、多層基板10の表面11上に実装される。
図12を参照して、電気素子内蔵型多層基板100A(図11参照)の製造方法においては、まず、基材層10A〜10G、表面21(主表面)を有する能動素子20(電気素子)、摺動部材30、および補助部材36が準備される。
電気素子内蔵型多層基板100Aにおいては、補助部材36が、基材層10A〜10Gが積層される方向において、摺動部材30に隣接するように配置される。補助部材36は、能動素子20に作用した外部応力に対する保護部材として作用する。能動素子20に、落下衝撃などの要因によって外部応力が作用した場合であっても、補助部材36は能動素子20に作用する応力を小さくすることができる。能動素子20が損傷したり、能動素子20(端子電極46)と層間配線45との接続が外れたりすることはさらに効果的に抑制されることができる。
