Semiconductor device and structure including semiconductor device

摘要

A semiconductor device for a microwave circuit includes a semiconductor substrate with an active element formed in the top surface, surface wirings on the top surface of the semiconductor substrate which are connected to terminals of the active element, and rear electrodes on the rear surface of the semiconductor substrate which are connected to the surface wirings by via holes. A structure includes the microwave semiconductor device, and a dielectric substrate which has surface wirings on a top surface. The semiconductor device is fixed with the dielectric substrate such that the rear electrodes of the semiconductor device are connected with the wirings on the top surface of the dielectric substrate.
