    摘要: One method includes forming a sacrificial gate structure above a substrate, forming a first sidewall spacer adjacent a sacrificial gate electrode, removing a portion of the first sidewall spacer to expose a portion of the sidewalls of the sacrificial gate electrode, and forming a liner layer on the exposed sidewalls of the sacrificial gate electrode and above a residual portion of the first sidewall spacer. The method further includes forming a first layer of insulating material above the liner layer, forming a second sidewall spacer above the first layer of insulating material and adjacent the liner layer, performing an etching process to remove the second sidewall spacer and sacrificial gate cap layer to expose an upper surface of the sacrificial gate electrode, removing the sacrificial gate electrode to define a gate cavity at least partially defined laterally by the liner layer, and forming a replacement gate structure in the cavity.

    摘要: A method for forming a patterned structure within a microelectronic structure uses a non-directly imageable organic material layer located over a substrate and a directly imageable inorganic material layer located upon the non-directly imageable organic material layer. The directly imageable inorganic material layer is directly imaged to form a patterned inorganic material layer. The patterned inorganic material layer is used as a first etch mask within a first etch method that etches the non-directly imageable organic material layer to form a patterned organic material layer. At least the patterned organic material layer is used as a second etch mask within a second etch method that etches the substrate to form a patterned structure within the substrate.
