Abstract
Semiconductor device, method for fabricating the same and electronic devices including the semiconductor device are provided. The semiconductor device comprises an interlayer insulating layer formed on a substrate and including a trench, a gate electrode formed in the trench, a first gate spacer formed on a side wall of the gate electrode to have an L shape, a second gate spacer formed on the first gate spacer to have an L shape and having a dielectric constant lower than that of silicon nitride, and a third spacer formed on the second gate spacer.
