ABSTRACT:
A tunable capacitor using an electrowetting phenomenon includes a first electrode; a second electrode which is spaced apart from the first electrode and faces the first electrode; a fluidic channel which is disposed between the first electrode and the second electrode; a first insulating layer which is disposed between the first electrode and the fluidic channel; and a conductive fluid which is disposed in the fluidic channel and moves along the fluidic channel when a direct current (DC) potential difference occurs between the first and second electrodes. Accordingly, it is possible to fabricate the tunable capacitor with the simplified fabrication process, good reliability and durability, and no restriction on the tuning range.
