Filed: 1980-06-20
Abstract: PURPOSE:To select not only a high-speed response property but a long lifetime, by forming annularly an electrochromic material having a functional group that performs a coloring and discoloring action on a display electrode. CONSTITUTION:A high molecular EC material having, at the side chain of a macromolecule, a functional group such as the viologen, tetrathiafluvalene, leucodyestuff, thionine, phthalocyanine, porphyrin that performs a coloring and discoloring action by an application of voltage is dissolved in a solvent to form an annular film 7 on a display electrode 2.

IPC: H01L21/331
Filed: 1989-04-06
Abstract: PURPOSE:To enhance a characteristic in order to realize a practical bipolar transistor by inserting an SiNx film into an emitter region which is situated at a boundary of an emitter-base junction or in a part close to an emitter junction. CONSTITUTION:A silicon nitride film 3 (SiNx; where 0.2<x<0.8) is situated at a boundary of a p-type base region 4 and an n-type emitter region 1 or between the n-type emitter region and on an n-type emitter region 1, 2 so as to be close to a junction between an emitter and a base. A donor concentration in the n-type emitter region 2 between the silicon nitride film 3 and the base region 4 is made smaller than an acceptor concentration in the base region 4. As a result, it is possible to selectively and effectively suppress a hole current from the base to the emitter in an n-p-n transistor. Thereby, it is possible to realize an ultrahigh-speed LSI whose characteristics such as a low base resistance, a low emitter capacity, a low-temperature operation and the like have been enhanced.
