A method of manufacturing a semiconductor device may include forming a fin structure on an insulator and depositing a gate material over the fin structure. The method may also include forming a sacrificial material over the gate material and planarizing the sacrificial material. An antireflective coating may be deposited on the planarized sacrificial material. A gate structure may then be formed by etching the gate material.

A method of manufacturing a semiconductor device may include forming a fin structure on an insulator and depositing a gate material over the fin structure. The method may also include depositing an organic anti-reflective coating on the gate material and forming a gate mask on the organic anti-reflective coating. The organic anti-reflective coating around the gate mask may be removed, and the gate material around the gate mask may be removed to define a gate.

A double gate metal-oxide semiconductor field-effect transistor (MOSFET) includes a fin, a first gate and a second gate. The first gate is formed on top of the fin. The second gate surrounds the fin and the first gate. In another implementation, a triple gate MOSFET includes a fin, a first gate, a second gate, and a third gate. The first gate is formed on top of the fin. The second gate is formed adjacent the fin. The third gate is formed adjacent the fin and opposite the second gate.

A method of manufacturing a semiconductor device includes forming a gate electrode over a substrate, implanting dopants into the substrate and activating the dopants using laser thermal annealing. During annealing, the laser and substrate are moved relative to one another, and the movement of the laser and the substrate relative to one another does not pause between and during activating one portion of the source/drain regions and activating another portion of the source/drain regions. Each pulse from the laser can respectively irradiate different portions of the source/drain regions, and a spot area of the laser is less than 50 millimeter2.
