    Abstract: Devices and methods of fabricating integrated circuit devices with reduced cell height are provided. One method includes, for instance: obtaining an intermediate semiconductor device having a substrate including a logic area and an SRAM area, a fin material layer, and a hardmask layer; depositing a mandrel over the logic area; depositing a sacrificial spacer layer; etching the sacrificial spacer layer to define a sacrificial set of vertical spacers; etching the hardmask layer; leaving a set of vertical hardmask spacers; depositing a first spacer layer; etching the first spacer layer to define a first set of vertical spacers over the logic area; depositing an SOH layer; etching an opening in the SOH layer over the SRAM area; depositing a second spacer layer; and etching the second spacer layer to define a second set of spacers over the SRAM area.

    Abstract: Conductive contact structure of a circuit structures and methods of fabrication thereof are provided. The fabrication includes, for instance, providing at least one contact opening disposed over a semiconductor substrate; forming a carbon-rich contact liner material including a carbon-containing species and an elemental carbon disposed therein, the carbon-containing species and the elemental carbon together defining a set carbon content within the carbon-rich contact liner material; and depositing the carbon-rich contact liner material conformally within the at least one contact opening disposed over the semiconductor substrate.
