Description of the Related Art With an increasing demand for high-speed semiconductor devices, fin field effect transistors (FinFETs) have been developed to replace conventional planar FETs. A FinFET typically includes a semiconductor fin that is used to form a channel region and source/drain regions at the sides of the semiconductor fin. A gate structure may be formed over the channel region of the semiconductor fin and a gate spacer may be formed on the sidewalls of the gate structure. The gate spacer may have a spacer width that is defined by a number of fin pitches, which is inversely proportional to the fin height. Accordingly, in order to obtain a desired spacer width, the fin height must be increased. However, with continued scaling of semiconductor devices, FinFETs having reduced fin height (and increased fin pitch) are desired. The provision of a fin height that is lower than the fin pitch causes a difficult etching process for patterning a gate spacer and an opening in a hard mask layer. Further, variations in fin height across a semiconductor substrate may increase the roughness of the top surface of the gate spacer, thereby affecting the gate sp be359ba680
