"exploded" IGBT, after the soot has been washed off:

Lots of melty carnage on the Gate/Source boundary!
Hi there,
I never cleaned of the soot of one of those, not to mention the sticky gel that comes with it

. very interesting. What type of IGBT was it? How many amps?
Are you sure it is the gate source that failed? Looks more like the source drain to me. The gate usaully has the smallest surface on an IGBT. It could be the structure to the left side of your picture though I usually see the gate in the middle of an IGBT. Also, gate source failures are usually more subtle. Sometimes they can be seen as a very faint darker line or spot escaping from the gate structure.
I have a couple of failed power modules lying around. I tried taking some pictures but I am sorry to say I do not have the equipment to take that kind of a macro shot. Your picture is amazing. Thanks for sharing.
