The planar process is not new; it goes back to the dawn of the integrated circuit.I am not that current on BJT process, but I believe that device is manufactured with planar process. Probably have special junction edge termination structures on the strips and N-epitaxy to handle the extra electric field and avoid puncture.
Anyway, the BVceo is 450V, as always, lower than the quoted BVces of 1KV.
I wonder how much more expensive it is compared to a similarly rated IGBT. Any idea on price?
Of course, it is not new. What I am saying is, a few years ago most of HV BJTs were fabricated with planar process and because I'm not really up to date with current BJT process, there might be currently newer approaches in HV BJTs manufacturing.The planar process is not new; it goes back to the dawn of the integrated circuit.
