Silica-based low dielectric constant materials having three-dimensional network structures containing siloxane backbones which comprise SiO tetrahedron structural units, as well as their production and use. The materials can be applied as interlayer dielectrics for semiconductor elements and the like.

Low dielectric constant materials and their production and use

A thin DC-DC converter arrangement which includes an inductor including a thin ring-shaped coil having a hole in its center and a thin ferrite core for providing a closed magnetic path passing through the central hole of the coil and interlinking the ring-shaped coil, a thin circuit board formed on its one surface with an electric circuit of the DC-DC converter, and a radiator having at least one flat part, wherein the inductor, the circuit board and the radiator are integrally assembled.
