  • Publication number: 20250056872
    Abstract: The present disclosure provides a semiconductor device. The semiconductor device includes a substrate, an active region on the substrate, and a gate structure, a source conductor, and a drain conductor disposed on the active region. The semiconductor device further comprises a first type doped region of the active region below the gate structure and a second type doped region of the active region adjacent to the first type doped region, and the first type doped region is different from the second type doped region. The second type doped region is configured to function as a resistor.

  • Publication number: 20230420452
    Abstract: Embodiments include a FinFET transistor including an embedded resistor disposed in the fin between the source epitaxial region and the source contact. A control contact may be used to bias the embedded resistor, thereby changing the resistivity of the resistor. Edge gates of the FinFET transistor may be replaced with insulating structures. Multiple ones of the FinFET/embedded resistor combination may be utilized together in a common drain/common source contact design.
