Abstract
【解決手段】配線基板(パッケージ)10は、その一方の面側の最外層の絶縁層12の、チップ搭載エリアに対応する箇所にキャビティCVが形成され、このキャビティCV内の絶縁層12の表面に露出するパッドP1と、キャビティCVの周囲の絶縁層12の表面に露出するパッドP2とを備えている。そして、このパッケージ10のキャビティCV内のパッドP1にチップ31がフリップチップ接続され、キャビティCVの周囲のパッドP2に他のパッケージ40が接続されて、POP構造の半導体装置30を構成している。
【選択図】図5
Description
図1は本発明の第1の実施形態に係る配線基板(半導体パッケージ)の構成を断面図の形態で示したものである。
図7は本発明の第2の実施形態に係る配線基板(半導体パッケージ)の構成を断面図の形態で示したものである。
図8は本発明の第3の実施形態に係る配線基板(半導体パッケージ)の構成を断面図の形態で示したものである。
上述した各実施形態では、パッケージ10(10a,10b)に電子部品(チップ)を収容するためのキャビティCVを、所要の形状にパターニングされたエッチングレジスト61(図2(c))をマスクにしてエッチングを施すことで形成した場合を例にとって説明したが、キャビティCVを形成する方法がこれに限定されないことはもちろんである。例えば、図2(b)の工程において、支持基材60上に形成すべきレジスト層を、図示のパターンとは逆のパターン(ポジとネガの関係)としためっきレジストとし、このめっきレジストを利用して所要のキャビティCVを形成することも可能である。
