Abstract
The ever-increasing power  requirement in renewable energies,  traction and power  transmission and distribution applications are  continuously pushing the technology  limits of high power  semiconductor especially IGBT,  regarding the maximum current  rating and maximum  current density. Innovation  in IGBT  chip and  packaging technologies  are  both required  to achieve  breakthrough  in chip  current density as well as package current rating limit.

In this seminar, several latest innovations in high power IGBT chip and packaging technologies will be presented. The .XT packaging  technology with IGBT5 chip enable reliable IGBT  module operation at Tvjop of  175oC or  ten-fold increase  in operation  lifetime. The  reverse-conduction IGBT  with  diode control (RCDC)  technology enable  monolithic functional  integration of  IGBT and diode,  led to  33% increase in  chip current  density. Finally,  the XHP  package offers  current rating  scalability by  easy paralleling of standardize module packages.
