Abstract: A calibration curve for a wafer comprising a layer on a substrate is determined. The calibration curve represents a local parameter change as a function of a treatment parameter associated with a wafer exposure to a light. The local parameter of the wafer is measured. An overlay error is determined based on the local parameter of the wafer. A treatment map is computed based on the calibration curve to correct the overlay error for the wafer. The treatment map represents the treatment parameter as a function of a location on the wafer.

Abstract: In some embodiments, a method of forming an etch mask on a substrate is provided that includes (1) forming a resist layer on a substrate; (2) exposing one or more regions of the resist layer to an energy source so as to alter at least one of a physical property and a chemical property of the exposed regions; (3) performing a hardening process on the resist layer to increase the etch resistance of first regions of the resist layer relative to second regions of the resist layer, the hardening process including exposing the resist layer to one or more reactive species within an atomic layer deposition (ALD) chamber; and (4) dry etching the resist layer to remove the one or more second regions and to form a pattern in the resist layer. Other embodiments are provided.

Abstract: Methods of laterally oxidizing features of a patterned substrate are described. A capping layer may be disposed above lateral features to laterally confine the oxidation. The oxidizable features may be material patterned near the optical resolution of a photolithography system using a high-resolution photomask. The oxidizable features may be wider than the spaces between the oxidizable features and may be about three times the width of the spaces. Oxidized portions may be formed on either side of repeated oxidizable features. The unoxidized portions may then be removed as part of a self-aligned double patterning (SADP) process. A gapfill layer deposited thereon may be etched or polished back to form alternating fill and non-sacrificial features.

Abstract: Provided are apparatus and methods for the sequential deposition and annealing of a film within a single processing chamber. An energy source positioned within the processing chamber in an area isolated from process gases can be used to rapidly form and decompose a film on the substrate without damaging underlying layers due to exceeding the thermal budget of the device being formed.
