It is referenced in a Microchip application note dated 2003 - but may have been added at a later date, and is mentioned elsewhere from 2006 on. So it's evidently "rather old" and as it is citing relative development changes between MOSFETS and IGBTs "within the last 2 years" it's highly likely that a close look at latest developments is in order.
