Abstract: A method of forming ferroelectric hafnium oxide (HfO2) in a substrate processing system includes depositing an HfO2 layer on a substrate, depositing a capping layer on the HfO2 layer, annealing the HfO2 layer and the capping layer to form ferroelectric hafnium HfO2, and selectively etching the capping layer to remove the capping layer without removing the HfO2 layer.

Abstract: A method of forming ferroelectric hafnium oxide (HfO2) in a substrate processing system includes depositing an HfO2 layer on a substrate, depositing a hafnium nitride (HfN) layer on the HfO2 layer; and annealing the HfO2 layer and the HfN layer to form ferroelectric hafnium HfO2.

Abstract: A method is provided. A substrate situated in a chamber is exposed to a halogen-containing gas comprising an element selected from the group consisting of silicon, germanium, carbon, titanium, and tin, and igniting a plasma to modify a surface of the substrate and form a modified surface.

Abstract: A method of forming ferroelectric hafnium oxide (HfO2) in a substrate processing system includes arranging a substrate within a processing chamber of the substrate processing system, depositing an HfO2 layer on the substrate, performing a plasma treatment of the HfO2 layer, and annealing the HfO2 layer to form ferroelectric hafnium HfO2.

Abstract: A method for forming nanowire semiconductor devices includes a) providing a substrate including an oxide layer defining vias; and b) depositing nanowires in the vias. The nanowires are made of a material selected from a group consisting of germanium or silicon germanium. The method further includes c) selectively etching back the oxide layer relative to the nanowires to expose upper portions of the nanowires; and d) doping the exposed upper portions of the nanowires using a dopant species.

Abstract: A method for selectively depositing a platinum layer on a substrate includes providing an electroless deposition solution including a platinum precursor and at least one of water and/or a pH balancing solution. A substrate including a patterned metal layer and one or more dielectric layers is immersed in the electroless deposition solution for a first predetermined period. The platinum layer is selectively deposited on the patterned metal layer but not on the one or more dielectric layers. The substrate is removed from the electroless deposition solution after the first predetermined period.
