Abstract:
1. A semiconductor device comprising: a substrate extending in a horizontal direction; a vertical transistor on the substrate, the vertical transistor comprising: a horizontal transistor on the substrate, the horizontal transistor comprising: wherein a portion of a gate electrode of the vertical transistor and a portion of the gate electrode of the horizontal transistor are at a same vertical position in the vertical direction relative to the substrate, wherein the first diffusion region of the horizontal transistor is contiguous with the first diffusion region of the vertical transistor; and wherein the first diffusion region of the horizontal transistor that is contiguous with the first diffusion region of the vertical transistor has a lowermost boundary that is higher in vertical position than a lowermost boundary of the first diffusion region of the vertical transistor, relative to an upper surface of the substrate.
