摘要： A high frequency semiconductor device has a semiconductor substrate such as the semi-insulating GaAs; a first metal layer disposed above the semiconductor substrate; a first dielectric thin film disposed on the first metal layer; and a second metal layer having a second metal strip disposed on the first dielectric thin film. Here, the first metal layer has a first metal strip, first and second ground metal plates sandwiching the first metal strip. And the first dielectric thin film is not disposed uniformly on the surface of the first ground metal plate so that the dielectric structure on the first metal strip differs from the dielectric structure under the second metal strip. The CPW is constituted by the first metal strip, the first and second ground metal plates, and the TFMSL is constituted by the second metal strip and the first ground metal plate. By employing the structure such that there is no dielectric thin film on the CPW portion, or that the thickness of the dielectric thin film on the CPW portion is configured to be less than the thickness of the dielectric thin film associated with the TFMSL portion, the effective dielectric constant ∈eff of the CPW portion is made lower than that of the conventional CPW, which employs a uniform and homogenous dielectric structure so that the CPW portion has the same thickness of the TFMSL portion. As the result, the adjustable range of the characteristic impedance Z0 of the high frequency transmission line, merged in the high frequency semiconductor integrated circuit, increases. Then the high-performance integrated circuits such as MMICs having the low transmission loss, the low crosstalk can be achieved.

摘要： A microwave transmitter/receiver module has a package that includes a high-frequency circuit board and an electromagnetically narrowed space. A semiconductor chip is mounted on the circuit board and is contained in the electromagnetically narrowed space. The electromagnetically narrowed space has a cutoff frequency that is higher than a carrier frequency for microwave communication. A receiver antenna pattern is formed on the top surface of the package and is electromagnetically connected to the semiconductor chip through a first slot. A transmitter antenna pattern is formed on the top surface of the package at a different position from the receiver antenna pattern and is electromagnetically connected to the semiconductor chip through a second slot. Since the antenna patterns are on the top surface of the package, the proper performance thereof is secured and the package is compact.
