    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.

    摘要: Resistors, semiconductor devices, and methods of manufacture thereof are disclosed. In one embodiment, a method of fabricating a resistor includes forming a semiconductive material over a workpiece, and patterning at least the semiconductive material, forming a gate of a transistor in a first region of the workpiece and forming a resistor in a second region of the workpiece. At least one substance is implanted into the semiconductive material of the gate of the transistor or the resistor so that the semiconductive material is different for the gate of the transistor and the resistor.
