Abstract An embodiment of the present invention includes a technique to remove a contaminant from a resist. A resist having a resist volume is spun in a centrifuige tube of a centrifuge at a pre-defined spinning rate corresponding to the resist volume in a time period to provide a gel. The gel is located under a lighting condition. The resist is decanted from the centrifuge tube.
