Abstract:
A method of forming isolation pillars for a gate structure, the method including: providing a preliminary structure including a substrate having a plurality of fins thereon, an STI formed between adjacent fins, an upper surface of the STIs extending higher than an upper surface of the fins, and a hardmask over the upper surface of the fins and between adjacent STIs; forming a first trench in a first selected STI and between adjacent fins in a gate region, and forming a second trench in a second selected STI and between adjacent fins in a TS region; and filling the first and second trenches with an isolation fill thereby forming a first isolation pillar in the gate region and a second isolation pillar in the TS region, the first and second isolation pillars extending below the upper surface of the STIs.

Claim (Index 1):
A method of forming isolation pillars for a gate structure, the method comprising:\n providing a preliminary structure, the preliminary structure including a substrate having a plurality of fins thereon, a shallow trench isolation (STI) formed between adjacent fins, an upper surface of the STIs extending higher than an upper surface of the plurality of fins, and a hardmask over the upper surface of the plurality of fins and between adjacent STIs; forming a first trench in a first selected STI in a gate region of the plurality of fins and a second trench in a second selected STI in a trench silicide (TS) region of the plurality of fins, the first trench being formed between adjacent fins in the gate region and the second trench being formed between adjacent fins in the TS region; and filling the first and second trenches with an isolation fill, the filling of the first trench forming a first isolation pillar in the gate region and the filling of the second trench forming a second isolation pillar in the TS region, the first and second isolation pillars extending below the upper surface of the STIs.
