    Abstract: A method of performing immersion lithography on a semiconductor substrate includes providing a layer of resist onto a surface of the semiconductor substrate and exposing the resist layer using an immersion lithography exposure system. The immersion lithography exposure system utilizes a fluid during exposure and may be capable of removing some, but not all, of the fluid after exposure. After exposure, a treatment process is used to neutralize the effect of undesired elements that diffused into the resist layer during the immersion exposure. After treatment, a post-exposure bake and a development step are used.

    Abstract: A method of semiconductor fabrication including an etching process is provided. The method includes providing a substrate and forming a target layer on the substrate. An etchant layer is formed on the target layer. The etchant layer reacts with the target layer and etches a portion of the target layer. In an embodiment, an atomic layer of the target layer is etched. The etchant layer is then removed from the substrate. The process may be iterated any number of times to remove a desired amount of the target layer. In an embodiment, the method provides for decreased lateral etching. The etchant layer may provide for improved control in forming patterns in thin target layers such as, capping layers or high-k dielectric layers of a gate structure.

    Abstract: The present invention includes a lithography method comprising forming a first patterned resist layer including at least one opening therein over a substrate. A protective layer is formed on the first patterned resist layer and the substrate whereby a reaction occurs at the interface between the first patterned resist layer and the protective layer to form a reaction layer over the first patterned resist layer. The non-reacted protective layer is then removed. Thereafter, a second patterned resist layer is formed over the substrate, wherein at least one portion of the second patterned resist layer is disposed within the at least one opening of the first patterned resist layer. The substrate is thereafter etched using the first and second patterned resist layers as a mask.
