Abstract
A structure includes a first dielectric over a trench silicide (TS) contact and over a gate structure, and at least one cavity in the first dielectric. A metal resistor layer is on a bottom and sidewalls of the at least one cavity and extends over the first dielectric. A first contact is on the metal resistor layer over the first dielectric; and a second contact is on the metal resistor layer over the first dielectric. The metal resistor layer is over the TS contact and over the gate structure. Where a plurality of cavities are provided in the dielectric, a resistor structure formed by the metal resistor layer may have an undulating cross-section over the plurality of cavities and the dielectric.
