A method for manufacturing a transistor includes forming a gate dielectric layer adjacent a semiconductor substrate. A gate electrode may be formed covering at least a portion of the gate dielectric layer. First and second doped regions of the semiconductor substrate may be formed proximate the gate electrode and separated by a channel region. First and second spacers may be formed at least partially in contact with the gate electrode. The first and second spacers may each comprise a material having a dielectric coefficient value less than the dielectric coefficient value of silicon dioxide. Third and fourth doped regions of the semiconductor substrate may be formed proximate the first and second spacers, respectively.
