Description
図1は、第1実施形態による半導体装置1の構成の一例を示す断面図である。半導体装置1は、積層体S1と、柱状電極30と、積層体S2と、ワイヤ70と、柱状電極80と、樹脂層90と、再配線層100と、金属バンプ150と、を備えている。半導体装置1は、例えば、NAND型フラッシュメモリ、LSI(Large Scale Integration)等の半導体パッケージでよい。
次に、全ての電極パッドが同じ方向を向く場合、すなわち、半導体チップがフェイスダウン状態およびフェイスアップ状態のいずれか一方である場合の比較例について説明する。
図5は、第2実施形態による半導体装置1の構成の一例を示す断面図である。第2実施形態では、第1実施形態と比較して、柱状電極80の配置が異なっている。
図6は、第3実施形態による半導体装置1の構成の一例を示す断面図である。第3実施形態は、柱状電極30に代えてワイヤ30aが設けられている点で、第1実施形態とは異なっている。
図7は、第4実施形態による半導体装置1の構成の一例を示す断面図である。第4実施形態では、第1実施形態と比較して、再配線層100に代えて配線基板100aが設けられ、半導体チップ200がさらに設けられている。
