DIRECT N/P LOCAL INTERCONNECT

DIRECT N/P LOCAL INTERCONNECT

Disclosed are devices that include a direct N/P local interconnect with minimal recess on shallow trench isolation (STI) oxide. This reduces undesirable coupling capacitance with active gate, which in turn improves AC performance of the device. Pull or even partial replacement of STI oxide with low-...

Zusammenfassung:Disclosed are devices that include a direct N/P local interconnect with minimal recess on shallow trench isolation (STI) oxide. This reduces undesirable coupling capacitance with active gate, which in turn improves AC performance of the device. Pull or even partial replacement of STI oxide with low-k dielectric can further reduce coupling capacitance.
