Abstract: A method for forming a modified resonator is provided. In one aspect, the method includes obtaining a resonator on top of a substrate, thereby forming an interface area between a bottom surface of the resonator and a top surface of the substrate. The resonator can include niobium or tantalum. The method also includes contacting the resonator and the substrate with a liquid acidic etching solution selected so as to have a higher etch rate towards the substrate than towards the resonator and a nonzero etch rate towards the resonator.

Abstract: A mechanism is provided to remove heat from an integrated circuit (IC) device die by directing heat through a waveguide to a heat sink. Embodiments provide the waveguide mounted on top of a package containing the IC device die. The waveguide is thermally coupled to the IC device die. The waveguide transports the heat to a heat sink coupled to the waveguide and located adjacent to the package on top of a printed circuit board on which the package is mounted. Embodiments provide both thermal dissipation of the generated heat while at the same time maintaining good radio frequency (RF) performance of the waveguide.

Abstract: A transmission line includes a ground conductor between first and second signal conductors. A substrate includes a first insulating layer and a second insulating layer having a relative permittivity lower than a relative permittivity of the first insulating layer. The first and second insulating layers are laminated in the thickness direction of the substrate and in contact with each other. The first and second signal conductors and the ground conductor are on an interface at which the first and second insulating layers are in contact with each other. The first and second signal conductors and the ground conductor each include a surface in contact with the first insulating layer and a surface in contact with the second insulating layer, the surface in contact with the second insulating layer being larger than the surface in contact with the first insulating layer.
