Abstract
【解決手段】モジュール基板(5)に、上から順に重ねた第1半導体チップ(4)、全体が平面状のスペーサ(3)及び第2半導体チップ(2)を有する。第1半導体チップのどの辺も第2半導体チップの第1辺(200)及び第2辺(202)よりも短く且つ第3辺(220)及び第4辺(221)よりも長い関係にあるものを重ねるとき、第3辺及び第4辺に平行なスペーサの縁辺を第1半導体チップの縁辺より内側にする。第2半導体チップの第2電極パッド(201、203)が第1半導体チップの縁辺に近接しても、スペーサが第1半導体チップの縁辺部分と第2半導体チップとの間に空間を確保するから、第2電極パッドに結合するワイヤ(210、211)は第1半導体チップに接触しない。この配置関係はスペーサを全体に単純な平面状にすることを保証する。
