Simulacra Sunday - Round 9

Kate Kelchner, a graduate student working in a nanofabrication lab at University of California, Santa Barbara, spotted these fellows using a scanning electron microscope! She says, "The 'skulls' are all less than 100 microns wide, or 1/10th of a millimeter. The patterns come from a photo-sensitive polymer that bubbles up around the edge of a sample.  A pattern is transferred to the polymer during a photolithography process, which is then transferred to the dielectric SiO2 layer underneath during a plasma etch process."
