Abstract:
An apparatus for processing a sample that has been etched in a first plasma chamber, the etching being performed to pattern the sample through a resist wherein the etching leaves residual corrosive compounds on the etched sample, comprising:a second plasma chamber, connected to said first plasma chamber, adapted to have a second plasma containing oxygen generated therein for application to the etched sample, said second plasma being formed in a gas atmosphere comprising at least oxygen, to remove said resist and said residual corrosive compounds from the sample, leaving remaining corrosive compounds; and a rinsing section, connected to said second plasma chamber, and adapted to apply to the sample from said second plasma chamber, a liquid, to remove said remaining corrosive compounds, formed in said first plasma chamber but not completely removed by said second plasma in said second plasma chamber.
