A method of forming source/drain contacts with reduced capacitance and resistance, including, forming a source/drain and a channel region on an active region of a substrate, forming a dielectric fill on the source/drain, forming a trench in the dielectric fill, forming a source/drain contact in the trench, forming an inner contact mask section on a portion of an exposed top surface of the source/drain contact, removing a portion of the source/drain contact to form a channel between a sidewall of the dielectric fill and a remaining portion of the source/drain contact, where a surface area of the remaining portion of the source/drain contact is greater than the surface area of the exposed top surface of the source/drain contact, and forming a source/drain electrode fill on the remaining portion of the source/drain contact.
A method of forming source/drain contacts with reduced capacitance and resistance, comprising:
