摘要： A semiconductor chip such as an MMIC is provided. The semiconductor chip has: a Si semiconductor as a substrate; and a low-loss transmission line, and can be easily connected to a circuit board on which the semiconductor chip is to be mounted and can ensure a stable GND potential. The semiconductor chip is a flip-chip semiconductor chip, and includes: a Si substrate; an integrated circuit manufactured on a main surface of the substrate; a dielectric film formed above the integrated circuit; and a conductor film for grounding formed on an upper surface of the dielectric film. The integrated circuit includes a wiring layer including a signal line which transmits signals for the integrated circuit. The signal line, the dielectric film, and the conductor film constitute a microstrip line.

摘要： A semiconductor integrated circuit device with a balun which is formed above a conductive semiconductor substrate and which includes a dielectric film, an unbalanced line for transmitting an unbalanced signal, and balanced lines for transmitting a balanced signal. The unbalanced line is placed opposite to the balanced lines via a nano-composite film that is a region of the dielectric film. The nano-composite film, interposed between the unbalanced line and the balanced lines, has a relative permittivity higher than that of other regions of the dielectric film. This allows suppression of electromagnetic coupling of transmission lines or passive elements other than the balun, thereby providing a semiconductor device with a wide-band and small-size balun.
