Resistor loaded inverter structures

An inverter comprising:

• a fin structure vertically orientated on a supporting substrate, the fin structure including both a resistive portion and a semiconductor portion monolithically integrated into a same fin structure that provides the fin structure vertically orientated on the supporting substrate;
• a transistor comprising a channel region present in the semiconductor portion of the fin structure and a gate all around (GAA) gate structure present on the channel region, wherein the gate all around gate structure comprises a gate dielectric directly on the channel region of the semiconductor portion of the fin structure and a gate electrode directly on the gate dielectric;
• and
• a passive resistor provided in the resistive portion of the fin structure positioned between the supporting substrate and the semiconductor portion of the fin structure and present on an electrically conductive material layer, wherein the channel region of the transistor and the passive resistor in the resistive portion of the fin structure are integrated into the same fin structure, an end of a source/drain region at an end of the channel region of the transistor being in direct contact with the passive resistor, wherein a width of a body portion of the passive resistor is not greater than a width of the channel region of the transistor,
• wherein the transistor includes a first source/drain region provided by a doped semiconductor layer present on the supporting substrate, and a second source/drain region is present at an end of the semiconductor portion of the fin structure opposite the first source/drain region,
• wherein the passive resistor is in direct contact with the second source/drain region of the semiconductor portion of the fin structure,
• wherein the second source/drain region is laterally surrounded by and electrically connected to a metal line.
