Abstract: Methods of forming structures including a photoresist underlayer and structures including the photoresist underlayer are disclosed. Exemplary methods include forming the photoresist underlayer that includes metal. Techniques for treating a surface of the photoresist underlayer and/or depositing an additional layer overlying the photoresist underlayer are also disclosed.

Abstract: Methods of forming a silicon oxycarbide layer on a surface of a substrate are disclosed. Exemplary methods include providing an oxygen-free reactant to a reaction chamber and performing one or more deposition cycles, wherein each deposition cycle includes providing a silicon precursor to the reaction chamber for a silicon precursor pulse period and providing plasma power for a plasma power period to form the silicon oxycarbide layer. Exemplary silicon precursors comprise a molecule comprising silicon, oxygen, carbon, and optionally nitrogen. The silicon precursor can further include one or more of (i) one or two silicon-oxygen bonds, (ii) one or two silicon-carbon bonds, or (iii) one carbon-carbon double bond.

Abstract: There is provided a method of filling one or more recesses by providing the substrate in a reaction chamber and introducing a first reactant to the substrate with a first dose, introducing a second reactant to the substrate with a second dose, wherein the first and the second doses overlap in an overlap area where the first and second reactants react and leave an initially substantially unreacted area where the first and the second areas do not overlap; introducing a third reactant to the substrate with a third dose, the third reactant reacting with the first or second reactant to form deposited material; and etching the deposited material. An apparatus for filling a recess is also disclosed.

Abstract: Methods and related systems for filling a gap feature comprised in a substrate are disclosed. The methods comprise a step of providing a substrate comprising one or more gap features into a reaction chamber. The one or more gap features comprise an upper part comprising an upper surface and a lower part comprising a lower surface. The methods further comprise a step of subjecting the substrate to a first plasma treatment and subjecting the substrate to a second plasma treatment. Thus the upper surface is inhibited while leaving the lower surface substantially unaffected. Then, the methods comprise a step of selectively depositing a material on the lower surface.
