A heterojunction bipolar transistor comprises a collector layer, a base layer formed on the collector layer and an emitter layer formed on the base layer. The emitter layer includes a first semiconductor layer covering the entire top surface of the base layer and a second semiconductor layer formed on a predetermined part of the first semiconductor layer. An inactivated region is formed, by ion implantation, in a region of the collector layer located below the base layer except for a part thereof corresponding to the second semiconductor layer. The edge of the inactivated region is located away from the edge of the second semiconductor layer, and a region of the first semiconductor layer between the edge of the inactivated region and the edge of the second semiconductor layer is depleted.

In a heterojunction FET in which source and drain areas are formed by carrying out high temperature annealing process after carrying out ion implantation in areas to be formed into source and drain areas, conventionally, the N-type carrier supply layer and the N-type active layer are doped with Si. In place of doping with Si, doping with Se or Te is adopted. Thereby, in high temperature annealing process for activating the ion implanted areas, which serves as source and drain areas, unlike the Si donor, inactivation of donor due to reaction with F-atoms occurs scarcely with respect to the diffusion of F-atoms on the surface of the epitaxial substrate, which adhered during the process. Further, since the Se and Te are impurities from VI-family, when the Se or Te occupies any grid position of atoms from III-family or V-family, the Se or Te serves as the donor. Accordingly, a high performance heterojunction FET of little deterioration of the FET characteristics can be obtained.

摘要:
Methods and apparatus for providing improving optical signal transmission results over standard mode fiber using a combination of negative chirp, low extinction ratio, and self-phase modulation transmission techniques in combination are described. The use of pre-transmission signal distortion in combinations with one or more of the other transmission techniques is also described. Pre-transmission signal distortion may be introduced by controlling a modulator with a large symmetric AC signal which causes the modulator to operation in a non-linear region or, alternatively, by using a relatively small non-symmetric AC signal to drive the modulator. Use of the small non-symmetric signal has the advantage of reduced power requirements. The pre-transmission distortion acts to counter some of the distortion introduced by the transmission of the signal over an optic fiber.

A nonstaining coating composition which comprises as essential components (A) a specific aliphatic sulfonic acid compound or amine salt thereof, (B) a compound having per molecule at least one functional group selected among carboxyl, a carboxylic acid anhydride group, and a carboxyl group blocked with an alkyl vinyl ether, (C) a specific organosilicate and/or a condensate thereof, and (D) a resin having epoxy groups and/or alkoxysilyl groups in the molecule; and a method of finish coating. Also, a stain resistant coating composition which comprises (F′) a specific modified resin and optionally (B) a compound having in the molecule at least one functional group selected from the group consisting of carboxyl group, carboxylic acid anhydride group and carboxyl group blocked with an alkylvinyl ether compound. They give a cured coating film which has nonstaining properties based on a high degree of hydrophilicity from immediately after the formation thereof and has satisfactory long-term weatherability, water resistance, and chemical resistance. The film can impart an excellent finish appearance to the article.

A paint substitute film 1 is provided which has an excellent property that permits universal application to a variety of components, for example to a complexly shaped component, without decreasing marketability of the component due to undesirable change in color. The paint substitute film 1 includes a color coat 3 which contains metallic pigments 5 and orientation inhibitors 6 for inhibiting orientation of the metallic pigments 5. When the paint substitute film 1 is bonded onto an exterior component of an automobile or the like, the paint substitute film 1 is drawn, but the orientation inhibitors 6 each serve as an obstacle to prevent the metallic pigments 5 from being uniformly oriented toward a direction parallel to the drawing direction. Accordingly, even after the paint substitute film 1 is drawn, rays of light incident on the film 1 diffuses upon reflection off the metallic pigments 5, and thus unfavorable alteration of color in the film 1 can be prevented.
