Several stickman figures sporting banners that read Smart and SIPMOS were discovered on a Siemens integrated circuit of unknown origin. AS we understand it, SIPMOS transistors are self-blocking field-effect transistors with low voltage requirements. The photomicrograph was donated to the Silicon Zoo by German photographer Karl E. Deckart, who is one of our featured microscopists. To view more of Karl's work, visit his Mikro/Makro website, which contains a sampler of his transmitted and reflected light images captured with a microscope.
