Abstract
【解決手段】上層基板の一面に第1上層キャビティ475を形成する段階と、上記上層基板の他面に上層半導体チップ480を実装する段階と、下層基板の一面に下層キャビティを形成する段階と、上記下層基板に形成された下層キャビティに下層半導体チップ435を実装する段階と、及び上記第1上層キャビティに上記下層半導体チップの一部が収容されるように上記下層基板上に上層基板を積層する段階と、を含むキャビティの形成されたパッケージオンパッケージの製造方法。キャビティの形成されたパッケージオンパッケージ及びその製造方法は、上層基板と下層基板にともにキャビティを形成して下層基板に実装された半導体チップがキャビティに収容されるのでパッケージの全体的な厚みを減らすことができる。
