Abstract
Description
以下、図面を参照して、第1の実施の形態の半導体装置の製造方法について、図1を用いて説明する。図1は、第1の実施の形態の半導体装置の製造方法の各工程を説明するための図である。なお、図1(A)〜図1(C)では、半導体装置の製造方法のうち、特に、リフローはんだ付け工程に関する工程の側図を時系列的に示している。また、図1(D)は、図1(C)の工程に対する参考例を示している。
第2の実施の形態では、第1の実施の形態の半導体装置の製造方法についてより具体的に説明する。まず、半導体装置について図2及び図3を用いて説明する。図2は、第2の実施の形態の半導体装置を示す平面図であり、図3は、第2の実施の形態の半導体装置を示す側面図である。なお、図2は、封止部材の図示を省略している。図3では、封止部材を破線で示している。また、第2の実施の形態では、複数の回路パターン層12、複数の半導体素子20、複数のコンタクト部品30、複数のボンディングワイヤ35、複数の外部接続端子40に対して、それぞれ区別することなく、同じ符号を付して同じ符号で説明する。なお、これらの構成以外の構成についても、複数あるものはそれぞれ区別することなく、同じ符号を付して同じ符号で説明する。但し、コンタクト部品については、複数のコンタクト部品30のうち、一部のコンタクト部品30をコンタクト部品30a〜30jとする。
以上により、ステップS11では、基板位置決め治具60が用いられ、ステップS13では、部品位置決め治具70が用いられ、ステップS15では、押え治具80が用いられている。このような基板位置決め治具60、部品位置決め治具70及び押え治具80が用いられて、図2及び図3に示した半導体装置50が製造される。
