Particles on Chips: Hair

Here is the large size picture of some strands spider silk on a 256 k DRAM. It shows that Mother Nature was still ahead then (1988) with regard to small structures. A typical strand of spider silk consists of several individual strings with diameters around 0.2 µm
However: Nowadays (2002) we are doing better than that. Minimal dimensions on state-of-the-art chips are 0.13 µm.
