Description
図1は、本発明を適用した半導体装置の第1実施形態を示す平面図である。この図に示す半導体装置1は、略方形状の複数(図1では2つで示す)の半導体チップ20,22を支持基板10上に搭載してなる、いわゆるMCM型の半導体装置である。
図2および図3は、外部接続回路40,42の一構成例と、チップ間接続部11におけるチップ内部回路30,32間の接続手法を説明する図である。ここで、図2(A)および図3(A)は、本願発明の一実施形態における手法の一例を示し、図2(B)は、特願2002−67969号や特願2002−191064号における手法の一例を示す。また、図2(C)および図3(C)は、チップ間接続部11における外部接続回路40,42近傍の変形例を示す。
図4は、第1実施形態の半導体装置1の製造方法を説明する図である。図4(A)に示すように、半導体チップ120,122を作製する。これらの半導体チップ120,122は、図1を用いて説明した半導体チップ20,22の前身であり、チップ内部回路30,32、外部接続回路40,42、さらには電極パッド50,52がそれぞれ設けられている。特に、チップ内部回路30,32からは、このチップ内部回路30,32の機能検査を行なうために必要十分な個数の外部接続回路40,42が、その四方に引き出されている。このため、この半導体チップ120,122の外部接続回路40,42の数、および電極パッド50,52の個数は、図1を用いて説明した半導体チップ20,22におけるこれらの個数よりも多くなっている。なお、図中、外部接続回路40a,42aおよび電極パッド50a,52aが、後の工程で物理的に切断除去される部分である。
図5は、本発明を適用した半導体装置の第2実施形態を説明する図である。この図は、第2実施形態の図3に対応するものである。この第2実施形態の半導体装置1は、入出力間をオンオフ可能な切替回路を用いて、チップ内部回路30,32間を直接に接続している信号ラインから保護回路406を切離可能に構成している点に特徴を有する。半導体チップ20,22としては、切替回路を備えている点が異なるだけであり、半導体装置1の平面図は、基本的には、図1に示したものと同じと考えてよい。
図6および図7は、本発明を適用した半導体装置の第3実施形態を説明する図である。ここで、図6(A)は、第3実施形態を示す平面図であり、図6(B)はこの平面図におけるA−A線断面図である。図7は、図6(A)の平面図におけるA−A線断面の詳細を示した図である。
図8は、本発明を適用した半導体装置の第4実施形態を示す断面図である。この第4実施形態の半導体装置1は、半導体チップ20,22同士をフェイスダウン実装している点に特徴を有する。その他の構成は第1あるいは第2実施形態の構成と同じであり、チップ間接続部11のチップ内部回路30,32を直接に接続している信号ライン上には保護回路406が設けられている。
