ABSTRACT:
A semiconductor device can include at least a first diffusion region formed by doping a semiconductor substrate and at least a second diffusion region formed by doping the semiconductor substrate that is separated from the first diffusion region by an isolation region. At least a first conductive line can comprise a semiconductor material formed over and in contact with the first diffusion region and the second diffusion region. A portion of the first conductive line in contact with the first diffusion region is doped to an opposite conductivity type as the first diffusion region. At least a second conductive line comprising a semiconductor material is formed in parallel with the first conductive line and over and in contact with the first diffusion region and the second diffusion region. A portion of the second conductive line can be in contact with the first diffusion region and doped to a same conductivity type as the first diffusion region. A portion of the second conductive line in contact with the second diffusion region can be doped to a same conductivity type as the second diffusion region.
