Abstract: First and second reference-potential generator units output first and second reference potentials V1 and V7, respectively, which correspond to first and second specific temperatures to be detected. An intermediate-potentials generator unit divides the potential difference between the reference potential V1 and the reference potential V7 to output intermediate potentials through nodes N2 to N6. A temperature-dependant-potential generator unit outputs the forward voltage drop of a diode which varies depending on the ambient temperature. A comparator compares one of the potentials of nodes N1 to N7 selected by a selector against the potential output by the temperature-dependant-potential generator unit and outputs the result of the comparison indicating the range of the ambient temperature.

Abstract: Input circuits connected to an external input terminal PAD via resistor elements are activated in response to the level transition of the clock signals supplied thereto for accepting input signals. In order to input signals applied to the external input terminal PAD clock signals having different phases are supplied to the respective input circuits. The cycle time of each one input circuit can be made longer by sequentially assigning the serial data supplied to the external input terminals in response to the clock signals having different clock signals. Since the input circuits are isolated from each other by means of the resistor elements, the influence of the kick back signal which occurs at first stage of each the input circuit upon the other input circuit can be made very small.

Abstract: To stably operate a semiconductor device comprising a plurality of input circuits which are connected to one external input terminal. Input circuits 10, 11, 12, 13 connected to an external input terminal PAD via resistor elements R1, R2, R3, R4, respectively, are activated in response to the level transition of the clock signals CK10, CK11, CK12, CK13 supplied thereto for accepting input signals. In order to input signals applied to the external input terminal PAD clock signals having different phases are supplied to the respective input circuits. The cycle time of each one input circuit can be made longer by sequentially assigning the serial data supplied to the external input terminals in response to the clock signals having different clock signals.

Abstract: A method of manufacturing a surface-emitting-type semiconductor laser device having a buried structure. A GaAlAs film is used as a mask layer in forming a GaAlAs/GaAs system burying part around a GaAlAs/GaAs system buried part. The mask layer can be formed continuously together with an active layer, a cladding layer and the like which constitute the buried part by means of a crystal growing apparatus for forming the buried part. When the system is etched, the GaAlAs film mask prevents the system buried part from becoming undercut so that the mask has better resistance to peeling during subsequent processing.
