Integrated circuits including multiple gate devices with dual threshold voltages and methods for fabricating such integrated circuits are provided. An exemplary method for fabricating an integrated device includes providing a semiconductor fin structure overlying a semiconductor substrate. The semiconductor fin structure has a first sidewall, a second sidewall opposite the first sidewall, and an upper surface. The method includes forming a first gate along the first sidewall of the semiconductor fin structure with a first threshold voltage. Further, the method includes forming a second gate along the second sidewall of the semiconductor fin structure with a second threshold voltage different from the first threshold voltage.
