Abstract: A catalyst carrier composed of a refractory inorganic oxide has a rotationally symmetrical shape having a hollow portion, such as a doughnut shape. An outer peripheral surface and the inner peripheral surface separating the hollow portion are linked by curved surfaces, and the height h of the carrier along the rotational symmetry axis is less than the outer diameter Do of the carrier. Using a catalyst having this carrier shape for a fixed bed makes it possible to prevent granular substances from causing catalyst plugging, and catalyst life can be extended because the catalyst-induced differential pressure increase is low even when granular substances accumulate on the catalyst. It is also possible to prevent the reaction fluid from undergoing channeling. Also provided is a hydrogenation reactor whose fixed bed is packed with the catalyst.

Abstract: A lead electrode is formed to expose an active base region. A lead electrode for an emitter electrode is formed on the lead electrode in an emitter region, through an insulating film. The insulating film on the lead electrode is then etched to form a contact hole. After that, the emitter contact hole is formed to expose the lead electrode. Also, a silicon nitride film SN is interposed between the lead electrode and insulating film and between the lead electrode and LOCOS oxide film each to decrease resistance of the lead electrodes.

Abstract: A lead electrode (57) is formed to expose an active base region (61). On the lead electrode (57) is formed a lead electrode (64) for an emitter electrode via an insulation film (56). When a base contact hole (65') for exposing the lead electrode (57) and an emitter contact hole for exposing the lead electrode (64) are formed at the same time, total thickness of the insulation film on the lead electrode (64) is thinner than that of the insulation layer on the lead electrode (57), which results in excessive etching on a part of the surface of the lead electrode to form recess. The lead electrode (64) is led out to a LOCOS film to form the emitter contact hole in a region on the LOCOS film to expose the lead electrode (64). Therefore, the recess having been formed on the lead electrode (64) upon forming the emitter contact hole is made to form on the LOCOS film outside the emitter region. The recess prevents depth of the emitter region from dispersing.
