NXP BC847B : Weekend die-shot

BC847B is one of the most common general purpose bipolar junction transistors (npn).
Die size 275x275 ┬Ám is so small, that thickness of the die is almost the same as width/height - it's almost a "silicon cube".
Probably it's one of these cases when dicing & packaging is the most challenging part of manufacturing :-)
