Description
本実施形態に係る半導体装置について図1乃至図3を用いて説明する。図1は本実施形態の半導体装置を示す断面図、図2は半導体装置に搭載される半導体素子を示す図で、図2(a)はその平面図、図2(b)は図1(a)のA―A線に沿って切断し矢印方向に眺めた断面図、図3は半導体素子が有する歪ゲージ部を拡大して示す断面図である。
ここで、Ksは歪ゲージの感度を表す係数(ゲージ率)、Lは金属抵抗体37の長さ、ΔLは金属抵抗体37の長さの変化量である。一般的な歪ゲージで使われている銅・ニッケル系合金やニッケル・クロム系合金では、ゲージ率はほぼ2である。
ここで、抵抗R1乃至抵抗R4の抵抗値が等しい(R1=R2=R3=R4)とすると、ΔVeは次式で表わされる。
図5は歪監視装置の動作を示すフローチャートである。ここでは、一例として、歪ゲージ部14が検出する歪量を継続的にモニターし、ハンダ層18の破壊疲労による半導体装置10の故障を未然に防止する場合について説明する。
本実施形態に係る半導体装置について、図9を用いて説明する。図9は本実施形態の半導体装置に搭載される半導体素子を示す平面図である。
