Hi,
I recuperated a lot of semiconductors but I now face the identification
of these item, principally mosfet and igbt.
How can I identify the one from the other with e.g. a dmm ?
Kind regards,

For a first pass, Mosfets have a parasitic internal diode from drain
to source. IGBTs don't, unless an extra part is added internally.
The basic IGBT is an n-channel MOSFET with a PNP emitter follower hanging
from the drain, so that test should clear things up.
