One space of silicon reverse engineering which has me is the delayering of a chip to see every layer which permits superior visibility into the circuitry. I do know of two methods: chemical etch and mechanical means.

On this video I attempt to make a mechanical grinder which might take micron ranges of fabric away: a partial success. Components are floor however I used to be not capable of hold the silicon completely flat. Extra examine of the business items is warranted!
