Main die size 1053x825 µm, frontend die 567x520 µm.


Main die:


Frontend die:


Packaged on a tiny ceramic interposer that fits into TO-99. All Gold-colored parts are 100% Gold. TO-99 pins though are only Gold-plated.


And now lets see it under SEM. Here we can see saw marks that only go half way in thickness, and crack going all the way.






Looking at the crack, FET die also seems to have different crystallographic orientation of Silicon substrate.
