@evilmonkeyzdesignz: Microscopic Bicycles on a silicon chip - This set of wafers that I picked up from Ebay have some tiny bicycles etched on them, one for each layer of the design. The chips contain a multitude of different test patterns, many of which are groups of the same element with small modifications. If I had to guess, these wafers were either from a University class on integrated circuit/wafer fab, or a research lab. - #technology #siliconwafer #STEM
