図1は導波管の一形態の説明図である。図1(A)は導波管の一形態の要部斜視模式図、図1(B)は図1(A)の面Xの断面模式図である。
ミリ波を超える高周波信号の伝送には、中空の導波管100を用いることで、低損失の信号伝送が行える。
図2(A)及び図2(B)には、上記図1(A)及び図1(B)に示した導波管100よりも厚みを薄くした導波管100aを例示している。この導波管100aは、上記導波管100よりも、下部導体110と上部導体120の間隔を狭め、且つ、同軸信号線200の、導波管100a内に露出する中心導体210の長さIを短くした構造を有している。
以下、本発明の一実施形態に係る導波管、及び導波管を備えた電子装置について、詳細に説明する。
導波管10は、下部導体11、上部導体12、及び側壁導体13を含む。下部導体11に対向するように上部導体12が設けられ、下部導体11と上部導体12は、側壁導体13で連結されている。導波管10の内部は、中空になっている。導波管10の外側には、絶縁層30が設けられている。
また、導波管10を設ける基板は、この基板20のような樹脂層21と半導体チップ22を含む擬似SoC基板に限定されるものではなく、半導体チップ、インターポーザ、回路基板等でもよい。ここでは説明の便宜上、図3(B)に示すような擬似SoC基板を基板20の例とする。
ここで、図4には、半導体チップ22の信号端子22ab上に設けた導体ピン40aと導波管10の上部導体12を接続(短絡)させない形態の電子装置1a(上記図1の導波管100を設けた電子装置に相当)の解析例を示している。このような電子装置1aの要部断面を、図4(A)に模式的に図示している。図4(A)に示す電子装置1aにおいて、導波管10の厚み(下部導体11と上部導体12の間の距離)は、432μmとしている。図4(B)は、このような電子装置1aの電磁界解析結果の一例である。図4(B)には、図4(C)に示すような、導波管10の2ポート(Port 1, 2)に設けた導体ピン40a間の距離を3mmに設定した場合の電磁界解析で得られた周波数(Frequency [GHz])とSパラメータ(S parameter [dB])の関係の一例を示している。S11を反射特性の評価に用い、S21を通過特性の評価に用いる。
ここで、図6には、導体ピン形状の異なる導波管10の変換部のモデルを例示している。図6(A)には、上記図1の導波管100に相当するモデル、即ち導体ピン40aを導波管10に短絡させないモデルA(Model A)を示している。一方、図6(B)及び図6(C)は、導体ピン40を導波管10に短絡させたモデルである。図6(B)には、一定の径の導体ピン40を導波管10に短絡させたモデルB(Model B)を示し、図6(C)には、異なる径の部位を設けた導体ピン40を導波管10に短絡させたモデルC(Model C)を示している。
図8~図12は導体ピン設計方法の一例の説明図である。
このようなピン42及びピン43の径Dbの調整によってインピーダンス整合が取れない場合には、ピン42及びピン43のうち、上側のピン43の径を更に調整する。尚、この調整時には、ピン41、ピン42及びピン43の各々の長さは変化させない。
まず、図13(A)に示すような、樹脂層21、及び樹脂層21に埋設された半導体チップ22を含む基板20(擬似SoC基板)を準備する。基板20の樹脂層21には、例えば、エポキシ系の樹脂にシリカ等のフィラー(充填剤)を混合したものを用いる。基板20は、半導体チップ22の周囲をその端子22a(22aa,22ab)の配設面側が露出するように樹脂層21で被覆し、これを加熱成形することによって、形成する。尚、基板20の樹脂層21には、半導体チップ22のほか、別の半導体チップや、チップコンデンサ等のチップ部品が更に埋設されてもよい。
尚、ここでは、3層のピン41、ピン42及びピン43を有する導体ピン40を形成する場合を例示した。4層以上のピンを形成する場合には、図19(A)の工程後、図19(B)の工程前に、ピンの層数に応じた回数だけ図17(B)~図19(A)の工程を繰り返し、その後、図19(B)以降の工程を行うようにすればよい。
以上説明した導波管10には、アンテナ機能を設けることもできる。
図21は電子装置の別例を示す図である。図21には、電子装置の別例の要部断面を模式的に図示している。
電子装置1Aの形成では、例えば、上記電子装置1の形成方法として述べた図18(A)のシード層53の形成工程までは同じとすることができる。その後の形成工程について、図22及び図23を参照して説明する。
そして、アセトン等のエッチャントを用いて、犠牲層62及び犠牲層64を除去することで、図23に示すような、中空部を有する導波管10を形成する。犠牲層62及び犠牲層64の除去時には、エッチャントが、上部導体12のスロット12aを通して導波管10内に流入し、導波管10外に流出することで、犠牲層62及び犠牲層64がエッチングされ、導波管10内から除去される。
また、以上の説明では、基板20に擬似SoC基板を用いる場合を例示した。このほか、上記のような導波管10(アンテナ機能を有する導波管10を含む)は、擬似SoC基板に限らず、半導体チップ単体の上に設けたり、プリント基板やインターポーザ等の回路基板の上に設けたりすることもできる。
