| 摘要 |
Disclosed herein is an MMIC package which comprises a base substrate, a composite capacitor substrate made of a ceramics plate mounted on the base substrate, an MMIC bare chip which functions as a high frequency semiconductor element and face-down bonded on the composite capacitor substrate, and an electroconductive covering which covers, together with the base substrate, the MMIC bare chip. In order to suppress the deterioration of the electrical characteristics of the above MMIC, the above components are so arranged that the interconnection length between the components is made to be minimum.
