摘要： A mask pattern designing method capable of achieving the reduction in the increasing OPC processing time, shortening the manufacture TAT of a semiconductor device, and achieving the cost reduction is provided. An OPC (optical proximity correction) process at the time when a cell is singularly arranged is performed to a cell library pattern which forms a basic structure of a semiconductor circuit pattern in advance, and a semiconductor chip is produced using the cell library pattern to which the OPC process has been performed. At this time, since the cell library pattern which has been OPC-processed in advance is influenced by the cell library patterns around it, the correction process thereof is performed to the end portions of the patterns near the cell boundary. As particularly effective OPC correction means, the genetic algorithm is used.

摘要： A serial-parallel converter/encoder unit 11 inputs a transmission symbol data at a transmission symbol rate that is one-Nth of a base-point symbol rate. A precoder/collator 13 creates a transmission symbol waveform at the base-point symbol rate. The transmission symbol waveform becomes a transmission signal after passing through a roll-off filter 14 with a band corresponding to the base-point symbol rate and a modulator 15. A reception signal demodulated by a demodulator 33 is input to a fractionally-spaced equalizer 38 that operates at the base-point symbol rate and is forcibly equalized at the transmission symbol rate by using a reference signal. A level of a signal output from the fractionally-spaced equalizer 38 at the transmission symbol rate is determined by a level determining unit 39 and becomes a reception symbol data by a sawtooth-function output unit 40.

摘要： Disclosed is a spectrum spread communication system which is hardly influenced by noises, and in which a frame structure can be identified at a receiving side without use of a frame synchronization signal. A spread code generator switches spread codes (“Scai” and “Scbi”) in each frame, and outputs it to a spread modulation unit. The spread modulation unit performs spread modulation of transmission data, and transmits it to a direct current power line. A reference code generator generates reference codes (“Scai” and “Scbi”) in the same code phase. Spread demodulation units performs spread demodulation of the received signal with use of the reference codes (“Scai” and “Scbi”), and output it to a selection unit. A frame synchronization detection unit identifies a frame structure on the basis of switching of a synchronization state of a code phase in a code phase synchronization detection unit. The selection unit outputs reception data by selecting spread demodulated data from the spread demodulation unit which is in a phase-synchronized state.

摘要： A method for designing a mask pattern realizes shortening the ever-growing time for the OPC treatment, decreases the fabrication TAT of a semiconductor device and cuts cost. A method for fabricating a semiconductor device uses the mask pattern designed. This invention performs the OPC treatment in advance on a cell library constituting the basic configuration of a semiconductor circuit pattern and prepares a semiconductor chip using the cell library that has undergone the OPC treatment. The method for designing a mask pattern includes the steps of designing a cell library pattern by executing for each of the cell libraries a treatment for correcting proximity effect directed to correcting the change of shape taking place during the formation of a pattern by the exposure of a mask pattern, designing a mask pattern by laying out the cell libraries and changing the amount of correction of proximity effect applied to the cell libraries in consideration of the influence of the cell library patterns disposed peripherally. This treatment for correction is executed by the degree of influence exerted by surrounding patterns collected in advance and the genetic algorithm.

摘要： A transmitting circuit 10 converts transmission data to a multilevel analog signal suitable for transmission. The multilevel analog signal is output to a cable 21 via an amplifier and a hybrid circuit 12. In the transmitting circuit 10, a waveform which compensates waveform deterioration at the cable 21 is generated. A reception signal from the cable 21 is input to a mixer 14 via the hybrid circuit 12 and an amplifier 13. The mixer 14 mixes the reception signal and a cancel signal output from a cancel signal generation circuit 17 so as to remove undesired signals. In a receiving circuit 15, the signal output from the mixer 14 is sampled by use of a plurality of sample-hold circuits, and subjected to analog sum-of-product computation which is performed by a matrix circuit for distortion compensation. Subsequently, the sampled signals are converted to digital signals. The digital signals are collectively subjected to processing such as parallel-serial conversion, whereby reception data and an evaluation signal are obtained. An adjustment control circuit 18 includes a CPU, and adjusts the respective circuits on the basis of the evaluation signal such that data can be correctly transmitted and received.
