Abstract

In this work, a novel tunable MIM capacitor with the meshed electrode is proposed first in order to improve the tunability characteristics using fringe fields. The capacitors were fabricated on a low-resistivity Si substrate employing lead zinc niobate (PZN) thin film dielectric. The fabricated capacitor with the meshed electrode, whose line width and spacing was $2.5{\mu}m$, achieved the effective capacitance tunability of 31 % that is higher value of 18.5 % than that of the conventional capacitor with the rectangular-type electrode.
