Abstract
A semiconductor device has a structure that reduces the parasitic capacitance by using a film with a low relative dielectric constant as the side wall material of the gate. The material with a low relative dielectric constant is preferably a material whose relative dielectric constant is less than the relative dielectric constant of an oxide film, i.e., less than about 3.9.
