摘要： In a plasma immersion ion implantation process, the thickness of a pre-implant chamber seasoning layer is increased (to permit implantation of a succession of wafers without replacing the seasoning layer) without loss of wafer clamping electrostatic force due to increased seasoning layer thickness. This is accomplished by first plasma-discharging residual electrostatic charge from the thick seasoning layer. The number of wafers which can be processed using the same seasoning layer is further increased by fractionally supplementing the seasoning layer after each wafer is processed, which may be followed by a brief plasma discharging of the supplemented seasoning before processing the next wafer.

摘要： The invention generally relates to pre-implant and post-implant treatments to promote the retention of dopants near the surface of an implanted substrate. The pre-implant treatments include forming a plasma from an inert gas and implanting the inert gas into the substrate to render an upper portion of the substrate amorphous. The post-implant treatment includes forming a passivation layer on the upper surface of the substrate after doping the substrate in order to retain the dopant during a subsequent activation anneal.

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.

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.
