Abstract
【解決手段】マルチチップモジュール20の断面方向のセンター面4Aを基準にして、同じ種類の構成材料同士が略面対称となる配置で設けられている。また、マルチチップモジュール20の断面方向のセンター面4Aを挟む上部構造体および下部構造体は、共に前記構成材料として基材および電子部品を含んでいる。
【選択図】図1
Description
電子部品31=シリコン基材30<封止樹脂35・・・・(I)
したがって、上部構造体45および下部構造体46の線膨張係数は、以下の(II)にて示す関係になる。つまり、
上部構造体45<下部構造体46・・・・・・・・・・・(II)
したがって、温度が上昇また下降すると、下部構造体46の方が上部構造体45と比較して大きく伸縮することになる。そして、下部構造体46が伸びれば、マルチチップモジュール20は下側(下部構造体46側)に向かって凸形状となるように反り、下部構造体46が縮めば、マルチチップモジュール20は上側(上部構造体45側)に向かって凸形状となるように反る。
そして、このようにマルチチップモジュール20の反りを低減させるためには、マルチチップモジュール20の断面方向におけるセンター面、換言すれば破線40を基準にして、上部構造体45および下部構造体46内の各構成の配置を略面対称にすればよいことを見出して、本願発明を完成させるに至った。
