Abstract: A doping apparatus includes a chamber and a plasma source. The plasma source generates dopant ions from a feed gas and provides the dopant ions to the chamber. A platen is positioned in the chamber proximate to the plasma source. The platen supports a substrate having planar and nonplanar features. At least one of a pressure proximate to the substrate, a flow rate of the feed gas, a power of the plasma, and a voltage applied to the platen is chosen so that dopant ions are implanted into both the planar and non-planar nonplanar features surfaces of the substrate.

Abstract: A technique for atomic layer deposition is disclosed. In one particular exemplary embodiment, the technique may be realized by a method for forming a strained thin film. The method may comprise supplying a substrate surface with one or more precursor substances having atoms of at least one first species and atoms of at least one second species, thereby forming a layer of the precursor substance on the substrate surface. The method may also comprise exposing the substrate surface to plasma-generated metastable atoms of a third species, wherein the metastable atoms desorb the atoms of the at least one second species from the substrate surface to form an atomic layer of the at least one first species. A desired amount of stress in the atomic layer of the at least one first species may be achieved by controlling one or more parameters in the atomic layer deposition process.

Abstract: A method of doping includes depositing a layer of dopant material on nonplanar and planar features of a substrate. Inert ions are generated from an inert feed gas. The inert ions are extracted towards the substrate where they physically knock the dopant material into both the planar and nonplanar features of the substrate.

Abstract: A technique for atomic layer deposition is disclosed. In one particular exemplary embodiment, the technique may be realized by an apparatus for atomic layer deposition. The apparatus may comprise a process chamber having a substrate platform to hold at least one substrate. The apparatus may also comprise a supply of a precursor substance, wherein the precursor substance comprises atoms of at least one first species and atoms of at least one second species, and wherein the supply provides the precursor substance to saturate a surface of the at least one substrate. The apparatus may further comprise a plasma source of metastable atoms of at least one third species, wherein the metabstable atoms are capable of desorbing the atoms of the at least one second species from the saturated surface of the at least one substrate to form one or more atomic layers of the at least one first species.

Abstract: A technique for boron implantation is disclosed. In one particular exemplary embodiment, the technique may be realized by an apparatus for boron implantation. The apparatus may comprise a reaction chamber. The apparatus may also comprise a source of pentaborane coupled to the reaction chamber, wherein the source is capable of supplying a substantially pure form of pentaborane into the reaction chamber. The apparatus may further comprise a power supply that is configured to energize the pentaborane in the reaction chamber sufficiently to produce a plasma discharge having boron-bearing ions.

Abstract: A plasma immersion ion implant apparatus and method, and a plasma chamber, each configured to provide a uniform ion flux and to dissipate the effects of secondary electrons are disclosed. The invention includes a plasma chamber including a dielectric tophat configuration and a conductive top section that may be liquid cooled. In addition, the invention provides a radio frequency (RF) antenna configuration including an active antenna that is coupled to an RF source and a parasitic antenna that is not directly coupled to any RF source, but may be grounded. The RF antenna allows for tuning of the RF coupling.
