    摘要: Methods of forming features and structures thereof are disclosed. In one embodiment, a method of forming a feature includes forming a first material over a workpiece, forming a first pattern for a lower portion of the feature in the first material, and filling the first pattern with a sacrificial material. A second material is formed over the first material and the sacrificial material, and a second pattern for an upper portion of the feature is formed in the second material. The sacrificial material is removed. The first pattern and the second pattern are filled with a third material.
