摘要:
The present invention provides a solid-state image pickup apparatus which is able to easily discharge signal charges in a signal accumulating section and which is free from reduction in the dynamic range of the element, thermal noise in a dark state, an image-lag and so forth even if the pixel size of the MOS solid-state image pickup apparatus is reduced, the voltage of a reading gate is lowered and the concentration in the well is raised. The solid-state image pickup apparatus according to the present invention incorporates a p-type silicon substrate having a surface on which a p+ diffusion layer for constituting a photoelectric conversion region and a drain of a reading MOS field effect transistor are formed. A signal accumulating section formed by an n-type diffusion layer is formed below the p+ diffusion layer. A gate electrode of the MOS field effect transistor is, on the surface of the substrate, formed between the p+ diffusion layer and the drain. The position of an end of the signal accumulating section adjacent to the gate electrode of the MOS transistor extends over the end of the reading gate electrode of the p+ diffusion layer to a position below the gate electrode.

The present invention relates to a network management system, and more particularly to a network management system for managing the states of plural alarm information generating from each one of the objects, which are to be managed, and stored in a state management area.Detailed information storage program of agents stores into detailed information files detailed information contained in alarm information transmitted from objects; alarm information coding program of a manager converts alarm information into alarm codes; and state management program stores the alarm codes into a state management area. A knowledge base enters combinations of alarm codes and effects of alarm information as decision patterns, and failure decision program decides upon failures by matching, at the time of receiving alarm information, the knowledge base and the state management area with each other.
摘要:
In a method of manufacturing a bonded semiconductor substrate, a SiGe mixed crystal layer, a silicon layer containing N-type impurities, a SiGe mixed crystal layer containing N-type impurities of high concentration, and a silicon layer containing N-type impurities of high concentration are formed in this order on a top surface of a silicon substrate by an epitaxial growth process to form a first semiconductor substrate. A silicon oxide film is formed on a surface of a silicon substrate to form a second semiconductor substrate. The first and second semiconductor substrates are bonded to each other by heat treatment, with their top surfaces contacting each other. The first semiconductor substrate is etched from the back surface thereof until the SiGe mixed crystal layer is exposed, and the SiGe mixed crystal layer is etched until the silicon layer containing N-type impurities is exposed. This method prevents the thickness of the element forming layer from varying.

The specification discloses a hetero bipolar transistor which comprises a semiconductor substrate, a first silicon layer serving as a collector, a first silicon-germanium layer serving as a base, a second silicon layer serving as a collector, and a second silicon-germanium layer. A side wall of the second silicon-germanium layer is in contact with side walls of the first silicon layer, the first silicon-germanium layer and the second silicon layer. The second silicon-germanium layer is disposed to surround the first silicon layer, the first silicon-germanium layer, and the second silicon layer, and has an energy band gap substantially the same as that of the first silicon-germanium layer.
