  • Semiconductor memory device and method for fabricating the same
    Patent number: 11812604
    Abstract: A semiconductor device includes a plurality of first conductive patterns extending parallel in a first direction on a substrate, a plurality of second conductive patterns extending parallel in a second direction crossing the first direction on the substrate, a plurality of buried contacts connected to the substrate between the plurality of first conductive patterns and between the plurality of second conductive patterns, and a landing pad connected to each of the buried contacts on the plurality of buried contacts. The landing pad includes a first side surface extending in the first direction in plan view and a second side surface extending in a third direction in plan view. The third direction is different from the first direction and the second direction in plan view.
