Abstract: PURPOSE:To reduce isolation width between metal wirings by providing the stepped part to electrically insulating layers laid to the adjacent wiring metal layers. CONSTITUTION:At the one main surface of semiconductor substrate 2, metal wirings 11a, 11b are respectively provided through an electrically insulating layer 3 on the stepped parts 3a, 3b formed on said layer 3. In this case, the wirings 11a, 11b have the width B', the space required for providing a single metal wiring is 1/2(B'+B')=B' because there is no gap between these wirings. However, in case it is ncessary for design to provide the metal wiring 11b and the wiring 11c adjacent thereto on the same surface having the stepped part, a gap A' is provided to both wirings. Therefore, an isolation width per metal wiring is, including provision of metal wiring 11d which has the stepped part and is adjacent to the wiring 11c, A'/2, width of only the wiring is B'/2. Since wirings are formed under the condition of A'=B', the minimum required width per wiring is B'.

IPC: H04L27/227
Filed: 1987-05-11
Abstract: PURPOSE:To avoid the over-control at noise superimposition by using an integration value of an arc tangent of the real part and the imaginary part of a data error between an output of an automatic equalizer and a discrimination output so as to control the output of the carrier phase error. CONSTITUTION:An error calculation section 3 calculates the data error between the output of the automatic equalizer and the output of the discriminator 1 and the result is outputted to an arc tangent integration section 4, which integrates the arc tangent of the real part and the imaginary part of the data error and a control signal is outputted to an output control section 5 by the result of integration. When the result of integration is nearly zero, the output control section 5 outputs the output of an imaginary part detection section 2 as it is as a carrier error and stops the output when the result of integration takes a large value. Thus, the over-control due to random noise is prevented, mis-control is less and the improvement of the error rate of a modulator- demodulator and the prevention of deviated equalization are attained.

Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To attain miniaturization and improvement in the performance and reliability of a structure for trimming by forming a conductor, with which the inner portion of an inductor is electrically pulled out onto a front side main surface or rear side main surface, on the inner wall surface of a through hole or bottomed hole previously provided on the side face of a substrate or on the substrate so as to control oscillation characteristics by partial cutting. SOLUTION: An inner conductor pattern layer 1-c constituting an inductor is trimmed, the electric length is extended just for 2αand the width is narrowed as well. Since the inductance of the inductor composed of the parallel ground conductor of a distribution constant type high frequency circuit can be improved by extending the electric length or narrowing the width, the oscillation frequency of a module before trimming is set a little higher than a prescribed value. Control is performed for providing the required oscillation frequency by lowering the oscillation frequency by remarkably changing the inductance constituting the oscillator by trimming.
