A method for manufacturing an article having polymeric residue that is to be removed during the manufacture of the article is disclosed. The article is introduced into a controlled environment of a processing tool having one or more processing chambers. Free radicals are generated from one or more reactant gases and introduced into at least one of the one or more processing chambers where they react with the polymeric residue. A cryogenic cleaning medium is supplied into at least one of the one or more processing chambers where the cryogenic cleaning medium removes the polymeric residue present after the free radicals react with the polymeric residue. The reactant gases are selected to facilitate removal of the polymeric residue with the cryogenic cleaning medium. The cryogenic cleaning medium is supplied with a pulsating flow via a nozzle implement that sweeps across the article. The pulsating flow may be generated via a piezo device or a rotating shaft with a hole the periodically enables or interrupts flow through a flow channel.

What is claimed is: 1. A method for manufacturing an article, the article having polymeric residue that is to be removed during the manufacture of the article, comprising the steps of: introducing the article into a controlled environment of a processing tool, the processing tool having one or more processing chambers; generating free radicals from one or more reactant gases and introducing the free radicals into at least one of the one or more processing chambers, wherein the free radicals react with the polymeric residue; and supplying a cryogenic cleaning medium into at least one of the one or more processing chambers, wherein the cryogenic cleaning medium removes the polymeric residue present after the free radicals react with the polymeric residue; wherein the reactant gases are selected to facilitate removal of the polymeric residue with the cryogenic cleaning medium; wherein the cryogenic cleaning medium is supplied with a pulsating flow via a nozzle implement that sweeps across the article. 2. A method for manufacturing an article, the article having polymeric residue that is to be removed during the manufacture of the article, comprising the steps of: introducing the article into a controlled environment of a processing tool, the processing tool having one or more processing chambers; generating free radicals from one or more reactant gases and introducing the free radicals into at least one of the one or more processing chambers, wherein the free radicals react with the polymeric residue; and supplying a cryogenic cleaning medium into at least one of the one or more processing chambers, wherein the cryogenic cleaning medium removes the polymeric residue present after the free radicals react with the polymeric residue; wherein the reactant gases are selected to facilitate removal of the polymeric residue with the cryogenic cleaning medium; wherein the cryogenic cleaning medium is supplied with a pulsating flow via a nozzle implement that sweeps across the article; wherein the pulsating flow is generated via a piezo device. 3. The method of claim 2, wherein the piezo device controllably activates a flow valve. 4. The method of claim 3, wherein the piezo device is coupled to a plunger, wherein the plunger is coupled to the flow valve. 5. A method for manufacturing an article, the article having polymeric residue that is to be removed during the manufacture of the article, comprising the steps of: introducing the article into a controlled environment of a processing tool, the processing tool having one or more processing chambers; generating free radicals from one or more reactant gases and introducing the free radicals into at least one of the one or more processing chambers, wherein the free radicals react with the polymeric residue; and supplying a cryogenic cleaning medium into at least one of the one or more processing chambers, wherein the cryogenic cleaning medium removes the polymeric residue present after the free radicals react with the polymeric residue; wherein the reactant gases are selected to facilitate removal of the polymeric residue with the cryogenic cleaning medium; wherein the cryogenic cleaning medium is supplied with a pulsating flow via a nozzle implement that sweeps across the article; wherein the pulsating flow is generated via a controllably interrupted flow channel. 6. The method of claim 5, wherein the controllably interrupted flow channel includes a rotating shaft that intersects the flow channel, wherein the rotating shaft includes a hole the periodically intersects with the flow channel. 7. The method of claim 6, wherein a motor provides rotational movement to the rotating shaft, wherein the rotational movement periodically aligns the hole of the rotating shaft with the flow channel. 8. A method for manufacturing an article, the article having polymeric residue that is to be removed during the manufacture of the article, comprising the steps of: introducing the article into a controlled environment of a processing tool, the processing tool having one or more processing chambers; generating free radicals from one or more reactant gases and introducing the free radicals into at least one of the one or more processing chambers, wherein the free radicals react with the polymeric residue; and supplying a cryogenic cleaning medium into at least one of the one or more processing chambers, wherein the cryogenic cleaning medium removes the polymeric residue present after the free radicals react with the polymeric residue; wherein the reactant gases are selected to facilitate removal of the polymeric residue with the cryogenic cleaning medium; wherein the cryogenic cleaning medium is supplied with a pulsating flow via a nozzle implement that sweeps across the article; wherein movement of the nozzle implement is generated by a slide mechanism and a drive motor coupled to the slide mechanism. 9. The method of claim 8, wherein the slide mechanism and drive motor are provided in the controlled environment of the processing tool. 10. The method of claim 9, wherein the slide mechanism and drive motor are provided in a chamber separate from the one or more processing chambers. 11. The method of claim 10, wherein a vacuum port is provided in the chamber in which the slide mechanism and drive motor are provided. 12. The method of claim 8, wherein the slide mechanism and drive motor are provided outside of the controlled environment of the processing tool. 13. The method of claim 12, wherein the slide mechanism and drive motor are magnetically coupled to the nozzle implement via a first magnet member that is outside the controlled environment of the processing tool and a second magnet member that is inside the controlled environment of the processing tool. 14. The method of claim 1, wherein the cryogenic cleaning medium is supplied in an oscillatory, vibratory or pulsating manner. 15. The method of claim 1, wherein the polymeric residue results from a photoresist removal process. 16. The method of claim 1, wherein the cryogenic cleaning medium is subjected to a multi-stage, multi-mode filtering process prior to being supplied to the second processing chamber. 17. The method of claim 1, wherein a first processing chamber provides plasma processing but not cryogenic processing. 18. The method of claim 17, wherein a second processing chamber provides cryogenic processing but not plasma processing. 19. The method of claim 1, wherein each of first and second processing chambers provide plasma processing and cryogenic processing. 20. The method of claim 1, wherein the nozzle assembly has a non-linear shape that corresponds to a shape of the article.
