Cleanrooms are used for a multitude of processes, and one of the most widely known uses is creating semiconductors. Many of these semiconductors are often found in electronics of all sorts and are part of our everyday society. The cleanrooms that build semiconductors are quite sophisticated and employ a host of tools to prevent these rooms from contamination. This often includes gowning procedures that cover users from head to toe and leave only a small bit of open skin on their face.
