Description
源電位を供給するための構造に関するものである。
4.2×10−4[Ωm]*5×10−6[m]/{0.1×10−3[m]*7×10−3[m]}≒3mΩ
となり、給電に使えることが判明した。
1)拡散時間は通常は10分以下である。しかし、従来デバイスを製造するプロセスの前に高濃度ウェルの拡散を行えば、従来デバイスの性能に与える影響はない。
2)ドーズ量は通常は1×1015cm−2である。しかし、通常の量産に使うイオン注入装置を用いても1×1016cm−2は可能である。また、1×1017cm−2のイオン注入が可能な製造装置も存在する。以上から、シミュレーションの条件は、量産したときの条件とほぼ同等である。また、貫通半導体領域のパターン寸法は、上述のように0.1mm×7mmとする。
また、裏面側には、n++型ウェル領域45に接続するようにAl或いはCuからなる裏面電極96を設ける。
