Abstract
A shielded metal-oxide-metal (MOM) capacitor includes a substrate, a lower shielding plate disposed on the substrate and in parallel with a major surface of the substrate, an upper shielding plate situated above the lower shielding plate and in parallel with the lower shielding plate, and a middle plate sandwiched between the lower shielding plate and the upper shielding plate. The middle plate includes two parallel first connecting bars extending along a first direction, a plurality of first fingers extending between the two parallel first connecting bars along a second direction, and an electrode strip spaced apart from and surrounded by the two parallel first connecting bars and the first fingers.
