Beschreibung
Zusammenfassung:	A monolithic microwave integrated circuit structure having: a semiconductor substrate structure having a plurality of active devices and a microwave transmission line having an input section, an output section and a interconnecting section electrically interconnecting the active devices on one surface of the substrate; a thermally conductive, electrically non-conductive heat sink; and a thermally conductive bonding layer for bonding the heat sink to the substrate, the thermally conductive bonding layer having an electrically conductive portion and an electrically non-conductive portion, the electrically conductive portion being disposed between the heat sink and an opposite surface of a portion of the substrate having the active devices and the electrically non-conductive portion being disposed on the opposite surface portion overlaying portion of the microwave transmission line section.
