Abstract
SOI基板上に形成される、電流密度の大きな横型IGBTを提供する。
【解決手段】
1つのコレクタ端子に対し、2つ以上の第二導電型ベース層からなるエミッタ端子を有する横型IGBT構造において、エミッタ領域の第二導電型ベース層をドリフト層より高濃度の第一導電型層で覆う構成を備える。これにより、エミッタ領域を覆う第一導電型層と埋め込み酸化膜の間のシリコン層が低抵抗化され、コレクタから離れたエミッタへの電流が増大し、電流密度が向上する。
【選択図】図1
Description
G2,G3,G4としていることのみ異なるものである。そして、分割されたゲート電極G1,G2,G3,G4を個別にオン,オフ制御することにより、IGBTのオン電圧,飽和電流,短絡耐量を変更可能にしている。
IGBTと同様に従来構造と比較し、低電圧で大電流を流すことが可能である。一方、ゲート電極G3,G4のみを駆動した場合、すべてのゲート電極を駆動した場合に対してオン電圧は高くなるものの、電流密度が低くなることで短絡耐量は向上する。
