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： 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： 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.
