Steve,
I had a look at the fractured chips in your photos.
The fracture surfaces have the typical appearance of a brittle fracture
(concoidal, if I remember correctly) that suggests that something hard has
hit the edges.
If it had been ESD damage I would have expected the surfaces to show melted
surfaces.
My two groats worth is that the silicon was damaged by handling damage
during die attach.
Regards
Eric Dawson
