we learned the other day that apparently they (specifically, Toshiba) actually do (or did) make IGBTs intended for analog amplification use, *including p-type IGBTs*, and that just feels extremely wild to us
we've never seen an IGBT used for anything other than power switching, and they're falling out of favor for that too as SiC MOSFETs become more available
and we've *definitely* never seen p-type ones

(p-channel MOSFETs and p-type IGBTs, and pnp BJTs for that matter, are generally substantially lower performance than the n-channel/n-type/npn counterparts due primarily to the fact that most common semiconductors have much lower hole mobility than electron mobility, so unless they're absolutely required in some application they're generally avoided)
-F
(some semiconductors have very similar electron and hole mobilities, and they wouldn't suffer from this problem. Some organic semiconductors have hole mobility higher than electron mobility, even! But silicon has very low hole mobility relative to electron mobility, and it's by far the most common and cheapest semiconductor.)
