そこで、図12(B)に示すように、ICチップ1021の能動面に樹脂突起1012を形成し、その樹脂突起1012の表面に導電膜1020を形成して、バンプ電極1010を構成する発明が提案されている(例えば、特許文献1参照)。なお、あらかじめICチップ1021のパッド1024の表面に絶縁膜1026を形成し、その絶縁膜1026の一部を開口することにより、パッド1024の接続部1022を形成しておく。そして、その接続部1022に対してバンプ電極1010の導電膜1020を延設することにより、当該バンプ電極1010をICチップ1021の電極端子として機能させることができる。
配線基板としての液晶パネル110は、ガラスやプラスチックなどで形成されるベース基板42及び基板112を備えている。ベース基板42と基板112は相互に対向配置され、図示しないシール材などによって相互に貼り合わされている。ベース基板42と基板112の間には図示しない電気光学物質である液晶が封入されている。ベース基板42の内面上にはITO(Indium Tin Oxide)などの透明導電体で構成された電極111aが形成され、基板112の内面上には上記電極111aに対向配置される電極112aが形成されている。なお、電極111a及び電極112aは直交するように配置されている。そして、電極111a及び電極112aは基板張出部111Tに引き出され、その端部にはそれぞれ電極端子111bx(配線パターン44)及び電極端子111cx(配線パターン44)が形成されている。また、基板張出部111Tの端縁近傍には入力配線111dが形成され、その内端部にも端子111dx(配線パターン44)が形成されている。
電気的接続部32の先端は、ベース基板42の端子111bx,111dxに圧接されることによって直接導電接触している。電気的接続部32と端子111bx,111dxとの間の導電接触部分の周囲には熱硬化性樹脂などの接着材料が硬化された接着剤50が充填されている。
以下、本実施の形態に係る半導体装置1の構成について説明する。なお、図3(A)〜図3(C)は、半導体装置1について説明するための図である。
次に、本実施の形態に係る半導体装置1の製造方法について説明する。図4(A)〜図4(C)は、本実施の形態に係る半導体装置1の製造方法について説明するための図である。
次に、電子デバイスの一例としての液晶表示装置100の製造方法について説明する。図7(A)〜図7(D)は、本実施の形態に係る液晶表示装置100の製造方法について説明するための図である。
前述した、配線パターン44に押し付けられた電気的接続部32の形状についての詳細を図8に沿って説明する。図8は、図7(D)のP−P視図であり、押し付けられた電気的接続部32の平面図である。
