A device including source-drain epitaxy contacts with a trench silicide (TS) liner wrapped around the source-drain contacts, and method of production thereof. Embodiments include a device having a gate structure formed over a substrate; source-drain epitaxy contacts including a trench silicide (TS) liner covering the source-drain epitaxy contacts; TS contacts formed on the TS liner over the source-drain epitaxy contacts; and a dielectric pillar disposed in a TS cut between the source-drain epitaxy contacts. The TS liner wraps around the source-drain epitaxy contacts, including bottom negatively tapered surfaces of the source-drain epitaxy contacts.
