Abstract: A sequential infiltration synthesis apparatus comprising: a reaction chamber constructed and arranged to hold at least a first substrate; a precursor distribution and removal system to provide to and remove from the reaction chamber a vaporized first or second precursor; and, a sequence controller operably connected to the precursor distribution and removal system and comprising a memory provided with a program to execute infiltration of an infiltrateable material provided on the substrate when run on the sequence controller by: activating the precursor distribution and removal system to provide and maintain the first precursor for a first period T1 in the reaction chamber; activating the precursor distribution and removal system to remove a portion of the first precursor from the reaction chamber for a second period T2; and, activating the precursor distribution and removal system to provide and maintain the second precursor for a third period T3 in the reaction chamber. The program in the memory is programmed with the first period T1 longer than the second period T2.

Abstract: The current disclosure relates to methods of depositing transition metal on a substrate. The disclosure further relates to a transition metal layer, to a structure and to a device comprising a transition metal layer. In the method, transition metal is deposited on a substrate by a cyclical deposition process, and the method comprises providing a substrate in a reaction chamber, providing a transition metal precursor to the reaction chamber in a vapor phase and providing a reactant to the reaction chamber in a vapor phase to form transition metal on the substrate. The transition metal precursor comprises a transition metal from any of groups 4 to 6, and the reactant comprises a group 14 element selected from Si, Ge or Sn.

Abstract: The method relates to a method of forming an enhanced unexposed photoresist layer from an unexposed photoresist layer on a substrate by increasing the sensitivity of the unexposed photoresist to exposure radiation. The method comprises: providing the substrate with the unexposed photoresist layer in a reaction chamber; providing a first precursor comprising a portion of a photosensitizer sensitive to exposure radiation in the reaction chamber; and, infiltrating the unexposed photoresist layer on the substrate with the first precursor.

Abstract: Metallic layers can be selectively deposited on one surface of a substrate relative to a second surface of the substrate. In some embodiments, the metallic layers are selectively deposited on a first metallic surface relative to a second surface comprising silicon. In some embodiments the reaction chamber in which the selective deposition occurs may optionally be passivated prior to carrying out the selective deposition process. In some embodiments selectivity of above about 50% or even about 90% is achieved.

Abstract: Methods are provided for depositing doped chalcogenide films. In some embodiments the films are deposited by vapor deposition, such as by atomic layer deposition (ALD). In some embodiments a doped GeSe film is formed. The chalcogenide film may be doped with carbon, nitrogen, sulfur, silicon, or a metal such as Ti, Sn, Ta, W, Mo, Al, Zn, In, Ga, Bi, Sb, As, V or B. In some embodiments the doped chalcogenide film may be used as the phase-change material in a selector device.
