  • Publication number: 20240098960
    Abstract: An integrated circuit structure in which a gate overlies channel region in an active area of a first transistor. The first transistor includes a channel region, a source region and a drain region. A conductive contact is coupled to the drain region of the first transistor. A second transistor that includes a channel region, a source region a drain region is adjacent to the first transistor. The gate of the second transistor is spaced from the gate of the first transistor. A conductive via passes through an insulation layer to electrically connect to the gate of the second transistor. An expanded conductive via overlays both the conductive contact and the conductive via to electrically connect the drain of the first transistor to the gate of the second transistor.
