Abstract:
A system for processing a wafer comprising:an ozonification chamber defining an enclosure and having at least a first opening for transferring a wafer therethrough from an area externally of the ozonification chamber into the enclosure; a wafer holder located within the ozonification chamber to hold the wafer in the enclosure; an ozone source system having an ozone-containing chamber in communication with the enclosure so that a first amount of ozone gas flows from the ozone-containing chamber into the enclosure and the wafer held by the wafer holder is exposed to the first amount of ozone gas, the ozone source system including at least one ultraviolet lamp which, when electric current flows therethrough creates ultraviolet light, the ultraviolet light therefrom radiating through a second amount of unconverted gas in the enclosure so that the second amount of unconverted gas is converted to a second amount of ozone gas and the wafer held by the wafer holder is exposed to the second amount of ozone gas.
