    • 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.
    • 形成引线电极(57)以暴露活性碱性区域(61)。 在引线电极(57)上经由绝缘膜(56)形成用于发射电极的引线电极(64)。 当同时形成用于使引线电极(57)露出的基极接触孔(65')和用于使引线电极(64)露出的发射极接触孔时,引线电极(64)上的绝缘膜的总厚度 比引线电极(57)上的绝缘层薄,这导致对引线电极的一部分表面的过度蚀刻以形成凹陷。 引线电极(64)被引出到LOCOS膜,以在LOCOS膜上的区域中形成发射极接触孔,以露出引线电极(64)。 因此,在形成发射极接触孔的引线电极(64)上形成的凹部被形成在发射极区域外部的LOCOS膜上。 该凹口防止发射极区域的深度分散。

    • The invention provides a lithium secondary battery using hydric boron carbonitride which is a layered compound represented by BC.sub.x N.sub.y H.sub.z, where 0.5.ltoreq.x.ltoreq.12, 0.7.ltoreq.y.ltoreq.1.5, and 0.01.ltoreq.z.ltoreq.3, as the active material of the negative electrode. This compound is obtained by a CVD process. The electrolyte is a solution of a lithium salt in an organic solvent. The material of the positive electrode is an oxide such as MnO.sub.2 or V.sub.2 O.sub.5, a sulfide such as MoS.sub.2 or TiS.sub.2 or a conductive organic polymer such as polyaniline. In this secondary battery Li is smoothly intercalated in and released from the hydric boron carbonitride of the negative electrode, and the energy density with respect to the active material of the negative electrode is sufficiently high. This battery bears a fairly large number of charge-discharge cycles. Also it is possible to use hydric boron carbonitride as the active material of the positive electrode of a lithium secondary battery in combination with negative electrode of metallic Li or hydric boron carbonitride with intercalation of a larger amount of Li.

    • 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.
