Abstract
The analysis of hole injection efficiency at the p+/n-drift layer junction in non-punchthrough IGBT structure is presented. This analysis takes into account carrier concentration variations by conductivity modulation. Good agreement between this analysis and simulation is found over a wide range of carrier lifetime and current density. The proposed analytical model of the hole injection efficiency as a function of collector width, collector concentration has been verified by device simulator, ATLAS.
