Semiconductor device and manufacturing method thereof










Image Number 14 for United States Patent #8198674.

To provide a semiconductor device including a first silicon pillar, an interlayer dielectric film provided on an upper surface of the first silicon pillar and having a through-hole filled with a conductive material, and a first-diffusion-layer contact plug provided on an upper-side opening of the through-hole. An area of a lower-side opening of the through-hole is equal to an area of the upper surface of the first silicon pillar, and an area of the upper-side opening of the through-hole is larger than the area of the lower-side opening of the through-hole. With this configuration, an area of a contact surface between the conductive material within the through-hole and the first-diffusion-layer contact plug is larger than the area of the upper surface of the first silicon pillar.
