Description
図1は、本発明の第1の実施形態に係る半導体装置の構成を示す図である。図1に示すように、本実施形態の半導体装置は、上面に第1の電極パッド204が複数個設けられた第1の半導体チップ207と、第1の半導体チップ207の上方に設けられ、上面に第2の電極パッド205が複数個設けられた第2の半導体チップ206と、第1の半導体チップ207および第2の半導体チップ206の外方に配置された空きリード端子(導電膜)203と、空きリード端子203を介して第1の電極パッド204と第2の電極パッド205とを接続するためのワイヤ201とを備えている。
図2(a)は、従来の半導体装置の一例を示す図である。また、図2(b)は、本発明の第2の実施形態の半導体装置の構成を示す図である。最初に、図2(a)を用いて従来の半導体装置の一例を簡単に説明する。
図3(a)は、本発明の第3の実施形態の半導体装置の示す図である。また、図3(b)は、図3(a)に示すIIIb-IIIb線における断面図である。
図4は、本発明の第4の実施形態の半導体装置の構成を示す断面図である。図4に示すように、本実施形態の半導体装置は、上面に第1の電極パッド708が複数個形成された第1の半導体チップ702と、第1の半導体チップ702の上方に設けられ、上面に第2の電極パッド707が複数個設けられた第2の半導体チップ701と、第1の半導体チップ702および第2の半導体チップ701の外方に配置された金属板705と、金属板705を介して、第1の半導体チップ702および第2の半導体チップ701を電気的に接続するためのワイヤ703と、金属板705の両側方に設けられた複数のリード端子706とを備えている。ここで、図示は省略するが、第1の半導体チップ702、第2の半導体チップ701、金属板705、ワイヤ703、およびリード端子706を覆う樹脂層がさらに形成されている。なお、リード端子706の一部は、樹脂層の外方へ突出している。
図5(a)は、従来の半導体装置の一例を示す図である。また、図5(b)、(c)は、本発明の第5の実施形態に係る半導体装置の構成を示す図である。最初に、図5(a)を用いて従来の半導体装置の一例を簡単に説明する。
図6(a)は、本実施形態の半導体装置に係る参考例を示す図である。また、図6(b)は、本発明の第6の実施形態の半導体装置の構成を示す断面図である。図6(a)は、上述の図5(b)と同様な構成であるため、ここでの説明は省略する。ここで、図6(a)に示す半導体装置では、空きリード端子904の一部が、樹脂層の外方へ突出しているため、誤って外部回路へ接続されてしまう危険性がある。以上のことから、図6(b)に示す本実施形態の半導体装置を見出した。
図7(a)は、従来の半導体装置の一例を示す図である。また、図7(b)は、本発明の第7の実施形態の半導体装置の構成を示す図である。図7(c)は、従来の半導体装置の不具合を示す図である。
