Looking inside a silicon die

Looking inside a silicon die

A very interesting branch of electrical engineering is the reverse engineering and analysis of silicon dies of semiconductors. The tools to play in this field are very specialized and I suspect very expensive.
In this video I went for the spend-no-money approach to see how far I could get at doing a top-side die polish of an integrated circuit. An arcane pursuit to be sure, but I was a bit pleased at how far I got using nothing more than some diamond paste and the equipment lying about in my workshop.
