Abstract: A signal process apparatus of the present invention is capable of shifting phases of signals inputted thereto and attenuating the signals, simultaneously. The signal process apparatus includes a dielectric member provided with a first and a second portions, a plurality of transmission lines positioned opposite the dielectric member for transmitting the signals and means for rotating the dielectric member to an axis perpendicular to a surface of the dielectric member which is parallel to the transmission lines. In the signal process apparatus, a dielectric constant of the first portion is different from that of the second portion. Each of the signals is inputted to a corresponding transmission line. After each of the signals is passing through the corresponding transmission line, it has a phase shifted by rotating the dielectric member.

Abstract: A method is provided for fabricating an analog and a digital semiconductor device close to each other on a surface of a semiconductor substrate. The analog device is formed on an insulating layer, and in a step configuration with respect to the insulating layer on the side of the digital device. Some deposition steps are used for forming both devices. In addition, the method teaches to form a spacer out of insulating material in the concave corner of the step configuration. The spacer prevents unwanted residual matter from remaining in the concave corner after an etching step and insulates the analog device better.
