@th this is really neat. But what is the structure in the bottom left corner? :blobcatglare2:

@0xC01DC0FFEE @th oh yeah, the weird L shaped thing. it took me a minute to spot it even after you mentioned it. I, too, wonder what it is...

@gsuberland @th my only guess would be some kind of fiducial? I dont see how it would serve any electrical purpose

@0xC01DC0FFEE @th iirc JFETs are typically constructed with two gate layers so maybe it's stitching the opposite side to a hidden metal layer that bonds back to the gate pad at the top right? but that's a total guess. could also be something related to the body terminal? or maybe even some sort of guard trace since I'm guessing this is intended for RF?

@f4grx @gsuberland @th I was thinking that too, but it kind of seems obvious enough where to cut on that die

@th do JFETs suffer from hotspots in the same way that MOSFETs do when operating in the outer regions of FBSOA?

@th looks like the answer is yes for SiC, but I couldn't find an answer for regular Si JFETs.
