An electronic device can include a semiconductor fin with a first gate electrode adjacent to a first wall, and a second gate electrode adjacent to a second wall. In one embodiment, a conductive member can be formed overlying the semiconductor fin, and a portion of the conductive member can be reacted to form the first and second gate electrodes. In another embodiment, a patterned masking layer can be formed including a masking member over a gate electrode layer, and portion of the masking member overlying the semiconductor fin can be removed. In still another embodiment, a first fin-type transistor structure can include the semiconductor fin, the first and second gate electrodes, and a first insulating cap. The electronic device can also include a second fin-type transistor structure having a second insulating cap thicker than the first insulating cap.
