• 論文の詳細を見る

• A new silicon-on-insulator (SOI) lateral insulated gate bipolar transistor (LIGBT) and lateral diode employing the separated Schottky anode (SSCA) is proposed and verified by the two dimensional numerical simulation based on experimental results. The Schottky barrier between the aluminum and lightly doped n-type silicon (Al/n-Si) of SSCA provides the potential difference between the n- anode contact and p+ anode to enhance the hole injection of p+ anode, which improves the forward current–voltage ($I$–$V$) characteristics. The anode region of SSCA-LIGBT is successfully decreased without negative differential resistance (NDR) regime and sacrificing the switching speed by employing contact. The SSCA structure applied to the diode also considerably improves the reverse recovery compared to the conventional p–i–n diode and reverse blocking capability compared to conventional Schottky diode.
