ABSTRACT:
In a manufacturing method of a hybrid integrated circuit device10according to the present invention, a first dummy pattern D1is provided on a first wiring layer18A. Furthermore, a second dummy pattern D2is provided on a second wiring layer18B. The first dummy pattern D1and the second dummy pattern D2are connected through a connection part25which penetrates an insulation layer17. Hence, heat dissipation through a dummy pattern can be actively performed. In addition, even in the cases where a multi-layered wiring is formed, it is possible to provide a circuit device which can secure a heat dissipation property.
