摘要： Provided is a semiconductor integrated circuit, in which a transmit pulse having an impulse waveform is produced using pull-up and pull-down currents of the charge pumps of pattern-generating cells of the pattern generator. During the first calibrating operation of semiconductor integrated circuit, the variation in amplitude of the transmit pulse is detected. At least one of pull-up and pull-down currents of the charge pumps is controlled according to a first calibration control signal responsive to the result of detection of the amplitude. During the second calibrating operation, the fluctuation in DC level just after producing of a repeat pulse of the transmit pulse is also detected. Imbalance between the pull-up and pull-down currents of the charge pumps are lowered according to a second calibration control signal responsive to the result of detection of the DC level fluctuation.

摘要： A multistage relay communication system 100 includes a trunk network 1 and branch networks 2 (2a, 2b), each of which includes one or more communication apparatuses 4. The communication apparatus 4 can switch between a trunk mode to operate in the trunk network 1 and a branch mode to operate in the branch network 2. In the trunk network 1, the communication apparatus 4 carries out fixing of a communication path and redundancy of data based on a path table in order to achieve real-timeness and a data arrival rate. Meanwhile, in the branch network 2, when a communication failure occurs, the communication apparatus 4 autonomously searches for a communication path and constructs a path table, in order to at least secure a data arrival rate even if real-timeness is impaired within an allowable range.

摘要： A manufacturing method is disclosed which ensures strength of a wafer and improves device performance. A thermal diffusion layer is formed from a front surface of a wafer. A tapered groove which reaches the thermal diffusion layer is formed from a back surface by anisotropic etching with alkaline solution. In-groove thermal diffusion layer is formed on side wall surfaces of the groove. A separation layer of a reverse blocking IGBT is configured of the thermal diffusion layer and the in-groove diffusion layer. The thermal diffusion layer is formed shallowly by forming the in-groove diffusion layer. It is possible to considerably reduce thermal diffusion time. By carrying out an ion implantation forming the in-groove diffusion layer and an ion implantation forming a collector layer separately, it is possible to select an optimum value for tradeoff between turn-on voltage and switching loss, while ensuring reverse blocking voltage of the reverse blocking IGBT.
