Abstract
A device including a self-aligned buried contact between spacer liners and isolated from a pull down (PD)/pull-up (PU) shared gate and an n-channel field-effect transistor (NFET) pass gate (PG) gate and method of production thereof. Embodiments include first and second high-k/metal gate (HKMG) structures over a first portion of a substrate, and a third HKMG structure over a second portion of the substrate; an inter-layer dielectric (ILD) over a portion of the substrate and on sidewalls of the first, second and third HKMG structures; a spacer liner on sidewalls of the ILD between the second and third HKMG structures; and a buried contact layer between the spacer liner and in a portion of the substrate.
