Abstract: A method of forming a film on a substrate by PEALD includes deposition cycles, each including (i) feeding a precursor in a pulse to a reaction space to adsorb a precursor on a surface of a substrate; (ii) after step (i), applying RF power to a second electrode to generate in the reaction space a plasma to which the precursor-adsorbed surface is exposed, thereby forming a sublayer on the surface; and (iii) applying a bias voltage to the second electrode while applying RF power in step (ii), which bias voltage is negative with reference to a potential on a surface of the first electrode, wherein the cycle is repeated to deposit multiple sublayers until a film constituted by the sublayers has a desired thickness.

Abstract: Methods for depositing silicon oxycarbonitride (SiOCN) thin films on a substrate in a reaction space 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 silicon precursor and a second reactant that does not include oxygen. In some embodiments the methods allow for the deposition of SiOCN films having improved acid-based wet etch resistance.

Abstract: There is provided a method of filling one or more gaps by providing the substrate in a reaction chamber and introducing a first reactant to the substrate with a first dose, thereby forming no more than about one monolayer by the first reactant on a first area; introducing a second reactant to the substrate with a second dose, thereby forming no more than about one monolayer by the second reactant on a second area of the surface, wherein the first and the second areas overlap in an overlap area where the first and second reactants react and leave an initially unreacted area where the first and the second areas do not overlap; and, introducing a third reactant to the substrate with a third dose, the third reactant reacting with the first or second reactant remaining on the initially unreacted area.

Abstract: A method of post-deposition treatment for silicon oxide film includes: providing in a reaction space a substrate having a recess pattern on which a silicon oxide film is deposited; supplying a reforming gas for reforming the silicon oxide film to the reaction space in the absence of a film-forming precursor, said reforming gas being composed primarily of He and/or H2; and irradiating the reforming gas with microwaves in the reaction space having a pressure of 200 Pa or less to generate a direct microwave plasma to which the substrate is exposed, thereby reforming the silicon oxide film.
