Abstract: A reaction system for processing semiconductor substrates is disclosed. In particular, the invention discloses an arrangement of a susceptor and a baseplate for when a substrate is placed into a reaction region. Magnets are embedded into the susceptor and the baseplate in order to create a gap between the two. As a result of the gap, the invention prevents an accumulation of gaseous materials that would exist in prior art systems as well as particle generation due to physical contact between parts.

Abstract: The disclosure relates to a chemical deposition, treatment and/or infiltration apparatus for providing a chemical reaction on and/or in a surface of a substrate. The apparatus may have a top and a bottom reaction chamber part forming together a closable reaction chamber and an actuator constructed and arranged for moving the top and bottom reaction chamber parts with respect to each other from a closed position to an open position so as to allow access to an interior of the reaction chamber. A top substrate holder is connected to the top reaction chamber part to hold a substrate at least when the reaction chamber is in the open position and a bottom substrate holder is connected to the bottom reaction chamber part to hold the substrate when the reaction chamber is in the closed position.

Abstract: Methods for selectively depositing oxide thin films on a dielectric surface of a substrate relative to a metal surface are provided. The methods can include at least one plasma enhanced atomic layer deposition (PEALD) cycle including alternately and sequentially contacting the substrate with a first precursor comprising oxygen and a species to be included in the oxide, such as a metal or silicon, and a second plasma reactant. In some embodiments the second plasma reactant comprises a plasma formed in a reactant gas that does not comprise oxygen. In some embodiments the second plasma reactant comprises plasma generated in a gas comprising hydrogen.

Abstract: The present invention relates to methods of forming silicon nitride thin films on a substrate in a reaction chamber by plasma enhanced atomic layer deposition (PEALD). Exemplary methods include the steps of (i) introducing an octahalotrisilane Si3X8 silicon precursor, such as octachlorotrisilane (OCTS) Si3Cl8, into a reaction space containing a substrate, (ii) introducing a nitrogen containing plasma into the reaction space, and wherein steps (i), (ii) and any steps in between constitute one cycle, and repeating said cycles a plurality of times until an atomic layer nitride film having a desired thickness is obtained.

Abstract: Processes are provided herein for deposition of organic films. Organic films can be deposited, including selective deposition on one surface of a substrate relative to a second surface of the substrate. For example, polymer films may be selectively deposited on a first metallic surface relative to a second dielectric surface. Selectivity, as measured by relative thicknesses on the different layers, of above about 50% or even about 90% is achieved. The selectively deposited organic film may be subjected to an etch process to render the process completely selective. Processes are also provided for particular organic film materials, independent of selectivity. Masking applications employing selective organic films are provided. Post-deposition modification of the organic films, such as metallic infiltration and/or carbon removal, is also disclosed.

Abstract: In some aspects, methods of forming a metal sulfide thin film are provided. According to some methods, a metal sulfide thin film is deposited on a substrate in a reaction space in a cyclical process where at least one cycle includes alternately and sequentially contacting the substrate with a first vapor-phase metal reactant and a second vapor-phase sulfur reactant. In some aspects, methods of forming a three-dimensional architecture on a substrate surface are provided. In some embodiments, the method includes forming a metal sulfide thin film on the substrate surface and forming a capping layer over the metal sulfide thin film. The substrate surface may comprise a high-mobility channel.

Abstract: Atomic layer deposition (ALD) type processes for producing metal containing thin films comprise feeding into a reaction space vapor phase pulses of metal containing cyclopentadienyl precursors as a metal source material. In preferred embodiments the metal containing cyclopentadienyl reactant comprises a metal atom that is not directly bonded to an oxygen or halide atom. In other embodiments the metal atom is bonded to a cyclopentadienyl compound and separately bonded to at least one ligand via a nitrogen atom. In still other embodiments the metal containing cyclopentadienyl compound comprises a nitrogen-bridged ligand.
