The logo/schematic, which is attached below, represents a 'story' - steps in a milling process.
Included in the attachment is both the old schematic (top) and photographs (bottom) that the schematic represents. The schematic is of a milling process.
A protective layer (yellow) is on the specimen film (red) grown on a substrate (grey).
The 'story' is: (a) A trench is cut to make a triangular prism. (b) Prism lifted out and attached to a needle. (c) Fill gap with adhesive. (d) Cut needle+prism into a square pyramid geometry. (e) Annular mill to sharpen the needle.
