Delightful journey through the layers of the chip.
Did you make any effort to make sure you were lapping the chip parallel to it's original circuit layers or just start lapping and allow the irregularities to add to the abstractions?

Very creative work here. Great micro imaging and great imagination with the titles. You may need to explain green stamps to younger viewers

A little bit of both Alan. After the top metal layers are lapped off it is almost impossible for me to lap each layer without going into the next and next before the upper is complete. On some CPU's I have counted no less than 10-12 different layers of composite materials. For me the best images are a combination of layers, distortions , scratches and infinite color and geometric combinations. I did a lot of looking and discovered that there is almost no work "out there" of this kind. Probably because most people don't have a microscope and if thy do they are not interested in microprocessors.
This whole venture for me was a steep learning curve and the discovery of this hidden "artwork" was a pleasant surprise.

Hey Alan......here is one in which the lapping breached a number of layers. It is incredible the gamut of color you can reach when this happens which is often.
The great fun with this cpu imaging is looking for the compositions with great color and geometry. I have spent hours looking a die (an isolated chip is referred to as a die) with different objective magnifications.
