Abstract
A capacitive tuning circuit includes radio frequency (RF) switches connected to an RF line. Each RF switch includes a phase-change material (PCM), a heating element underlying an active segment of the PCM and extending outward and transverse to the PCM, and RF terminals having lower metal portions and upper metal portions. Alternatively, the RF terminals can have a trench metal liner separated from a trench metal plug by a dielectric liner. At least one capacitor is formed in part by at least one of the lower metal portions, upper metal portions, or trench metal liner. The capacitive tuning circuit can be set to a desired capacitance value when a first group of the RF switches is in an OFF state and a second group of the RF switches is in an ON state.
