  • Publication number: 20210312997
    Abstract: A semiconductor memory device includes a first word line formed over a first active region. In some embodiments, a first metal line is disposed over and perpendicular to the first word line, where the first metal line is electrically connected to the first word line using a first conductive via, and where the first conductive via is disposed over the first active region. In some examples, the semiconductor memory device further includes a second metal line and a third metal line both parallel to the first metal line and disposed on opposing sides of the first metal line, where the second metal line is electrically connected to a source/drain region of the first active region using a second conductive via, and where the third metal line is electrically connected to the source/drain region of the first active region using a third conductive via.

  • Publication number: 20210280584
    Abstract: Various embodiments of the present disclosure are directed towards an integrated chip (IC) having a device section and a pick-up section. The IC includes a semiconductor substrate. A first fin of the semiconductor substrate is disposed in the device section. A second fin of the semiconductor substrate is disposed in the pick-up section and laterally spaced from the first fin in a first direction. A gate structure is disposed in the device section and laterally spaced from the second fin in the first direction. The gate structure extends laterally over the semiconductor substrate and the first fin in a second direction perpendicular to the first direction. A pick-up region is disposed on the second fin. The pick-up region continuously extends from a first sidewall of the second fin to a second sidewall of the second fin. The first sidewall is laterally spaced from the second sidewall in the first direction.
