  • Publication number: 20190089044
    Abstract: [Problem] To realize high reliability and high functionalization while suppressing characteristics variation in a multilayer interconnection substrate used in a microwave or millimeter-wave band integrated with an antenna. [Resolution Means] A multilayer substrate for high frequency with an antenna element formed on a surface. The multilayer substrate for high frequency has an intermediate substrate. The intermediate substrate consists of a low-temperature co-fired glass-ceramic substrate and has intermediate insulating layers consisting of a glass-ceramic and an internal conductor formed between these intermediate insulating layers. A surface insulating layer consisting of an organic material having a dielectric constant lower than a glass-ceramic material is stacked on a surface of the intermediate substrate. An outer-side via conductor penetrating this surface insulating layer is configured by a sintered metal that forms a metallic bond with a wiring conductor in the substrate.
