The Industry’s Largest Semiconductor Plant Recreated with Legos— Behind the Scenes of a Miniature Cleanroom

  • mail
In the previous video that Samsung DS put together (title/link), we showed how cleanrooms in a semiconductor fabrication line stay clean using a miniature plant created with Legos. The miniature cleanroom had so many exquisite details that it could have been mistaken for computer graphics. Are you interested in finding out how Samsung’s Pyeongtaek campus, the industry’s largest semiconductor plant, has been recreated with Legos? Why Are Semiconductors Manufactured in Cleanrooms?

The reason why many circuits can be drawn onto a semiconductor chip that is smaller than a fingernail is because of the highly precise nanoscale processes. In these processes, even a tiny dust particle or a virus particle of 1 μm in size that is invisible to the naked eye can lead to a defect. That’s why the semiconductor fabrication line should be kept very clean, and hence the name “cleanroom.” A Miniature Plant Illustrating How a Cleanroom Works

Dimensions of Samsung’s Pyeongtaek campus, which is the largest semiconductor plant in the industry

Cleanrooms for semiconductor fabrication are much safer and cleaner than you would think. Samsung’s DS division miniaturized the Pyeongtaek Campus Line 1 to a 1:520 scale using the Legos.

The first step was to develop a miniature design that can be built using Legos. And then we started assembling once the Lego blocks were ready. About 15,000 pieces were assembled over 8 days (based on 10 hours per day) to build the miniature cleanroom. After the hard work, we were able to complete the miniature cleanroom, looking quite similar to the actual one. No Dust Allowed! Stop Motion Videos Show How Cleanrooms Stay Clean

The completed mini cleanroom was moved to a studio to be filmed showing how semiconductor manufacturing lines are kept clean. The videos were filmed using the stop motion technique. Often times, we had to film for 4–5 hours for just one scene. Also, filming and editing were done simultaneously to minimize errors. It was particularly difficult to illustrate how the internal air filtration systems that are used to maintain cleanliness operate, including the air showers, dry cooling coils, and ULPA filters. You can find out more about how we built the miniature cleanroom in the video!
