Abstract

A spin dry etching process includes loading an object into a dry etching system. A dry etching process is performed to the object, and the object is spun while the dry etching process is being performed. The spin dry etching process is performed using a semiconductor fabrication system. The semiconductor fabrication system includes a dry etching chamber in which a dry etching process is performed. A holder apparatus has a horizontally-facing slot that is configured for horizontal insertion of an etchable object therein. The etchable object includes either a photomask or a wafer. A controller is communicatively coupled to the holder apparatus and configured to spin the holder apparatus in a clockwise or counterclockwise direction while the dry etching process is being performed. An insertion of the etchable object into the horizontally-facing slot of the holder apparatus restricts a movement of the object as the dry etching process is performed.
