Abstract:
1. A semiconductor device comprising: a semiconductor substrate; a first isolation region and a second isolation region provided in the semiconductor substrate, the first and second isolation regions extending in a first direction and being adjacent to each other; a first word line and a second word line provided in the semiconductor substrate, the first and second word lines extending in a second direction crossing the first direction and being adjacent to each other; a first upper insulating region and a second upper insulating region provided on the first word line and the second word line, respectively, the first and second upper insulating regions extending in the second direction and being adjacent to each other; a source/drain diffusion region provided in a surface area of the semiconductor substrate and between the first isolation region and the second isolation region, the source/drain diffusion region including a portion positioned between the first upper insulating region and the second upper insulating region; and a first conductive portion provided in the source/drain diffusion region, the first conductive portion being provided between the first upper insulating region and the second upper insulating region, and the first conductive portion being formed of a material containing metal.
