Abstract
【解決手段】 集積回路装置1内に、本来の機能を果たす本体回路2と独立して評価用回路3を設ける。評価用回路3には、本体回路2を動作させるクロック4よりも周波数が高いクロックを入力して動作させる。本体回路2を動作させるクロック4よりも周波数が高いクロックで動作する評価用回路3は、本体回路2よりも早く劣化する。この劣化は、通常、評価用回路3の出力信号の遅延に現れ、この遅延を検出する劣化検出部6を設けて、評価用回路3の劣化を検出する。

Description
と、例えば当初のしきい値電圧Vth0 とを比較し、その変化量に基づいてトランジスタの劣化の程度を検出する。あるいは、評価により検出されたしきい値電圧Vth1 が所定の基準値に対する許容範囲内に納まっているか否かによって、トランジスタの劣化を判断する。
