Abstract: A waveguide structure includes a signal line and two static lines. The signal line is disposed between the static lines in a first direction. The static lines and the signal line are disposed parallel to one another. Each static line includes a first conductive pattern, a second conductive pattern, and a third conductive pattern. The first conductive pattern and the signal line are disposed on an identical plane of a dielectric layer. A thickness of the first conductive pattern is substantially equal to a thickness of the signal line. The second conductive pattern is disposed on the first conductive pattern. A width of the first conductive pattern is larger than a width of the second conductive pattern in the first direction. The third conductive pattern is disposed on the second conductive pattern. A width of the third conductive pattern is larger than the width of the second conductive pattern.

Abstract: A radiofrequency filter includes a substrate, an isolation structure, an electrically conductive structure, a spacer structure, a dielectric layer, a patterned electrically conductive film, a first contact structure, and a second contact structure. The isolation structure is disposed in the substrate. The electrically conductive structure is disposed on the isolation structure. The spacer structure is disposed on the substrate and located on a sidewall of the electrically conductive structure. The dielectric layer is disposed on the electrically conductive structure. The patterned electrically conductive film is disposed on the dielectric layer. At least a part of the dielectric layer is located between the electrically conductive structure and the patterned electrically conductive film in a vertical direction. The first contact structure and the second contact structure are disposed on and electrically connected with the patterned electrically conductive film.
