Abstract:
Embodiments of the invention generally relate to a method of cleaning a substrate and a substrate processing apparatus that is configured to perform the method of cleaning the substrate. More specifically, embodiments of the present invention relate to a method of cleaning a substrate in a manner that reduces or eliminates the negative effects of line stiction between semiconductor device features. Other embodiments of the present invention relate to a substrate processing apparatus that allows for cleaning of the substrate in a manner that reduces or eliminates line stiction between semiconductor device features formed on the substrate.
