Abstract:
The present invention provides an apparatus and a method for an ultraviolet cleaning tool. The cleaning tool includes ultraviolet source spaced apart from a surface having contaminant particles. The ultraviolet source can create ozone between the surface and the ultraviolet source which breaks the chemical bonds between particles and the surface. The apparatus includes a gas feed which introduces a gas to aid the chemical bond. Additionally, the gas feed can introduce a gas to remove the particles from the surface.
