Filed: 1996-02-16
Abstract: PROBLEM TO BE SOLVED: To efficiently reduce NOx in an exhaust gas containing oxygen more than the necessary quantity for oxidizing a reducing component by allowing nitrogen oxides in the exhaust gas to react with a hydrocarbon to produce a nitrogen-containing hydrocarbon compound and bringing the nitrogen-containing hydrocarbon compound into contact with a catalyst to reduce, the compound.

IPC: H01L27/118
Filed: 1989-02-09
Abstract: PURPOSE:To highly integrate by opening electrode openings only for a bipolar transistor element to be used to electrically connect, and forming a wiring region on a bipolar transistor element not used. CONSTITUTION:Electrode windows 25 are opened only for bipolar transistor elements (T) 15, 16 to be used, electrically connected, and T15, 16 not used are as a wiring region. Thus, an active region and a wiring region can be freely determined. Accordingly, a circuit design can be optimized to eliminate a wasteful region. Since the T15, 16 not used are used as wiring regions, it is not necessary to provide a wiring only region. Therefore, the T15, 16 can be disposed on a conventional wiring only region. A resistance layer 21 is formed on an element isolating region 22 to form the layer 21 without increasing the size of a semiconductor chip 11. Further, since the layer 21 not used becomes the wiring region, even if the layer 21 is formed on the region 22, the wiring region can be obtained.
