摘要： By forming an isolated semiconductor layer or electrode layer on a semiconductor surface between neighboring field effect transistors and element separating trenches which are deep enough to reach at least the semi-insulating substrate or the hetero junction interface on the buffer layer, low frequency oscillation of a compound semiconductor integrated circuit can be reduced. By controlling the thickness of the buffer layer having a hetero junction to at most 150 nm, the low frequency oscillation can be reduced. By forming materials separating adjacent elements with a width of at most 2 .mu.m which reach from the element region surface to the buffer layer having hetero junction so as to enclose the element regions and etched regions in the neighborhood of the elements or so as to enclose the element regions in the etched regions and by controlling the angle of the sides of the etched regions against the semiconductor layer surface to 10.degree. to 60.degree., wires can be prevented from short-circuiting.

摘要： A tire-information administration system includes a plurality of sensor modules installed in tires; at least one reception module configured to receive data from the sensor modules; and a central control module configured to command the reception module to acquire data from the sensor modules. The central control module includes a predetermined number of connection ports for the reception module, assigned in advance to each sensor modules; and a specifically configured control means. The control means sequentially outputs at predetermined sampling time a command of data acquisition from a sensor module, to the connection port assigned to each sensor module; assigns the connection port to the sensor module for the next sampling, when there is a data input from the sensor module in response to the command; assigns data acquisition from the sensor module to another connection port, and assigns the other connection port to the sensor module for the next sampling, when there is no data input from the sensor module even by the command issuance. Thus, the tire-information administration system maintains communications even in case of troubles of the reception modules or damages of tires.

摘要： A bipolar transistor having the enhanced characteristics is fabricated by etching a base mesa, which is formed below an emitter mesa (upper emitter layer) and a base electrode, to have jut regions on the edges of its generally rectangular region. A mask film, e.g., insulating film, is formed to cover the rectangular region and jut regions, and the base layer is etched by use of the insulating film for masking thereby to form a base mesa. Consequently, abnormal etching can be prevented from occurring along the base electrode and emitter mesa on the edges of the area where the base electrode and emitter mesa confront, and the increase of resistance between the base layer and the emitter layer can be prevented, whereby the bipolar transistor can have the enhanced characteristics.

摘要： The present invention achieves the enhancement of a manufacturing yield factor and the reduction of manufacturing cost in a manufacturing method of a semiconductor device having a hetero junction bipolar transistor (HBT), a Schottky diode and a resistance element. The present invention is directed to the manufacturing method of a semiconductor device in which respective semiconductor layers which become a sub collector layer, a collector layer, a base layer, a wide gap emitter layer and an emitter layer are sequentially formed over one surface of a semiconductor substrate and, thereafter, respective semiconductor layers are processed to form the hetero junction bipolar transistor, the Schottky diode and the resistance element in a monolithic manner. An emitter electrode of the hetero junction bipolar transistor, a Schottky electrode of the Schottky diode and a resistance film of the resistance element are simultaneously formed using a same material (for example, WSiN). Accordingly, the man-hours can be reduced and the manufacturing cost of the semiconductor device can be reduced.

摘要： In an electrophotographic member employing an amorphous silicon photoconductive layer, a part which is at least 10 nm thick inwardly of the amorphous silicon layer from the surface (or interface) of the amorphous silicon layer is made of amorphous silicon which has an optical forbidden band gap of at least 1.6 eV and a resistivity of at least 10.sup.10 .OMEGA..cm. The electrophotographic member exhibits a satisfactory resolution and good dark-decay characteristics. Further, a region which has an optical forbidden band gap narrower than that of the amorphous silicon forming the surface (or interface) region is disposed within the amorphous silicon layer to a thickness of at least 10 nm, whereby the sensitivity of the electrophotographic member to longer wavelengths of light can be enhanced.
