This itty bitty Starship Enterprise was created by Takayuki Hoshino & Shinji Matsui, in one-billionth scale by 30 kV Ga+ focused-ion- beam CVD using phenanthrene gas for the The 47th International Conference on Electron, Ion and Photon Beam Technology and Nanofabrication Bizarre/Beautiful Micrograph Contest back in 2003. I have no idea what the hell any of it means, but I do know this... it's tiny. Teeny tiny.
How tiny? The model measures a mere 8.8 micrometers long and there are 1000 micrometers in 1 millimeter which is about how big the period is at the end of this sentence.
