great job with the stitching I would say, there are no
deformations recognizable. The blending for the vertical
rows is very smooth. Between each of the rows some
changes in luminance can be seen. I wonder if a stronger
blending would make this less recognizable.
Thanks for the explanation elsewhere that the shadow
pictures from some of the structures result from the
microscopes optics (e.g. the S from MOS). I wondered
if these were hidden layers.

In the structures to the right, I believe there are
some gates recognizable. These "L-JL"-pairs (upside down)
cold be some drivers stages. I thought on CMOS first
(PMOS coupled with NMOS along with a pre-driver), but
all these old chips are NMOS only.

Nevertheless I see the darkfield images same as you,
they give a big plus in recognizing lower layer
structures.
