Ds. Byeon et al., The separated shorted-anode insulated gate bipolar transistor with the suppressed negative differential resistance regime, MICROELEC J, 30(6), 1999, pp. 571-575
The separated shorted-anode LIGBT (SSA-LIGBT), which suppresses effectively
the negative differential resistance regime, is investigated by performing
2-dimensional numerical simulation. In order to suppress the negative diff
erential resistance regime, the SSA-LIGBT increases the pinch resistance by
employing the highly resistive n-drift region as an electron conduction pa
th instead of the lowly resistive n buffer region of the conventional SA-LI
GBT. The SSA-LIGBT shows the remarkably decreased forward voltage drop when
compared with the conventional SA-LIGBT and shows the one-order faster tur
n-off time than that of the LIGBT. (C) 1999 Elsevier Science Ltd. All right
