    摘要： A method of plasma immersion ion implantation of a workpiece having a photoresist mask on its top surface prevents photoresist failure from carbonization of the photoresist. The method includes performing successive ion implantation sub-steps, each of the ion implantation sub-steps having a time duration over which only a fractional top portion of the photoresist layer is damaged by ion implantation. After each one of the successive ion implantation sub-steps, the fractional top portion of the photoresist is removed while leaving the remaining portion of the photoresist layer in place by performing an ashing sub-step. The number of the successive ion implantation sub-steps is sufficient to reach a predetermined ion implantation dose in the workpiece.

    摘要： A method of removing resist material from a substrate having a magnetically active surface is provided. The substrate is disposed in a processing chamber and exposed to a fluorine-containing plasma formed from a gas mixture having a reagent, an oxidizing agent, and a reducing agent. A cleaning agent may also be included. The substrate may be cooled by back-side cooling or by a cooling process wherein a cooling medium is provided to the processing chamber while the plasma treatment is suspended. Substrates may be flipped over for two-sided processing, and multiple substrates may be processed concurrently.

    摘要： A method and apparatus for removing excess dopant from a doped substrate is provided. In one embodiment, a substrate is doped by surfaced deposition of dopant followed by formation of a capping layer and thermal diffusion drive-in. A reactive etchant mixture is provided to the process chamber, with optional plasma, to etch away the capping layer and form volatile compounds by reacting with excess dopant. In another embodiment, a substrate is doped by energetic implantation of dopant. A reactive gas mixture is provided to the process chamber, with optional plasma, to remove excess dopant adsorbed on the surface and high-concentration dopant near the surface by reacting with the dopant to form volatile compounds. The reactive gas mixture may be provided during thermal treatment, or it may be provided before or after at temperatures different from the thermal treatment temperature. The volatile compounds are removed. Substrates so treated do not form toxic compounds when stored or transported outside process equipment.
