ZTX851 Die Photos

Found die photos for the ZTX851 on the EEV Blog.

About all I can find on Zetex technology is the "Matrix Geometry" used to provide low distributed base resistance to what appears to be a single transistor. Rather than many transistors we have many base contacts.

Tanks for the photos of the die.
A clever 3D transistor, in a planar technology.

I remember the first planar transistors in the 60's, a major break through giving amazing characteristics for that time.
Planar was the way to go and still going on.
Signal low power transistors are very small and extremely flat.
