    Abstract: Embodiments of the invention include a semiconductor device and methods of forming such devices. In an embodiment, the semiconductor device includes a source region, a drain region, and a channel region formed between the source region and drain region. In an embodiment, a first interlayer dielectric (ILD) may be formed over the channel region, and a first opening is formed through the first ILD. In an embodiment, a second ILD may be formed over the first ILD, and a second opening is formed through the second ILD. Embodiments of the invention include the second opening being offset from the first opening. Embodiments may also include a gate electrode formed through the first opening and the second opening. In an embodiment, the offset between the first opening and the second opening results in the formation of a field plate and a spacer that reduces a gate length of the semiconductor device.
