An object is to provide a semiconductor device of which a manufacturing process is not complicated and by which cost can be suppressed, by forming a thin film transistor using an oxide semiconductor film typified by zinc oxide, and a manufacturing method thereof. For the semiconductor device, a gate electrode is formed over a substrate; a gate insulating film is formed covering the gate electrode; an oxide semiconductor film is formed over the gate insulating film; and a first conductive film and a second conductive film are formed over the oxide semiconductor film. The oxide semiconductor film has at least a crystallized region in a channel region.

Semiconductor device, and manufacturing method thereof

Process gas discharged from a bypass pipe to a gas exhaust system can be prevented from diffusing back to the inside of a process chamber without having to install a dedicated vacuum pump at the downstream side of the bypass pipe. The substrate processing apparatus includes a process chamber accommodating a substrate, a gas supply system supplying process gas from a process gas source to the process chamber for processing the substrate, a gas exhaust system configured to exhaust the process chamber, two or more vacuum pumps installed in series at the gas exhaust system, and a bypass pipe connected between the gas supply system and the gas exhaust system. The most upstream one of the vacuum pumps is a mechanical booster pump, and the bypass pipe is connected between the mechanical booster pump and the rest vacuum pumps located at a downstream side of the mechanical booster pump.

Substrate Processing Apparatus

An energy storage device includes a first electrode comprising a first material and a second electrode comprising a second material, at least a portion of the first and second materials forming an interpenetrating network when dispersed in an electrolyte, the electrolyte, the first material and the second material are selected so that the first and second materials exert a repelling force on each other when combined. An electrochemical device, includes a first electrode in electrical communication with a first current collector; a second electrode in electrical communication with a second current collector; and an ionically conductive medium in ionic contact with said first and second electrodes, wherein at least a portion of the first and second electrodes form an interpenetrating network and wherein at least one of the first and second electrodes comprises an electrode structure providing two or more pathways to its current collector.

Compositions are provided which contain (a) one or more polysiloxanes comprising at least one reactive functional group; a plurality of particles; and, optionally, one or more curing agents comprising at least one functional group that is reactive with any reactive functional group of polysiloxane (a). Additionally, a process for applying the multi-component composite coatings described above to a substrate and coated substrates are provided. A process for preparing the coating compositions also is provided. The multi-component composite coating compositions of the invention provide highly scratch resistant color-plus-clearcoatings capable of retaining scratch resistance after weathering.

A powder coating composition of the invention comprises a film-forming polymeric component having a d(v,50) in the range of from 25 to 50 microns or a d(v,70) in the range of from 25 to 70 microns, which composition incorporates by dry-blending at least one appearance-modifying additive component and a further component comprising wax-coated silica or consisting of alumina together with aluminium hydroxide. The appearance-modifying additive may be a gloss-reducing component, a texturing component, a metallic or mica component, a colouring pigment, or a further film-forming polymeric material compatible with the first film-forming polymeric material and differing in colouration therefrom, and the further additive may be alumina together with aluminium hydroxide or wax-coated silica together with alumina and/or with aluminium hydroxide or wax-coated silica. Preferably, no more than 70 % by volume of the particles in the film-forming polymeric material are less than 50 microns. A kit of the invention comprises the individual additive components prior to mixing. The kit allows for the flexibl production of a variety of finishes from a gloss powder coating composition, for example a matt or textured or metallic or sparkle finish or a matt textured finish, a matt metallic finish, an antique finish or a contrast texture or metallic sparkle finish.

Powder coating compositions

An aminoplast-curable film-forming composition is disclosed. The film-forming composition is a crosslinkable composition comprising (1) a material containing a plurality of carbamate and/or urea functional groups and (2) an aminoplast crosslinking agent. The composition provides a coating with improved acid etch resistance, making the coating particularly useful as an automotive clear coat.

A color-plus-clear coating system is disclosed. A pigmented or colored basecoat is first applied to a substrate followed by the application of a transparent topcoat to the basecoat. The transparent topcoat composition is a crosslinkable composition comprising (1) a material containing a plurality of carbamate and/or urea functional groups and (2) an aminoplast crosslinking agent. The topcoat composition provides a composite coating with improved acid etch resistance, making the composite coating particularly useful as an automotive topcoat.

Method for preparing color-clear composite coatings having resistance to acid etching

A color-plus-clear coating system is disclosed. A pigmented or colored base coat is first applied to a substrate followed by the application of a transparent top coat to the base coat. The transparent top coat composition is a liquid crosslinkable composition comprising a polyepoxide and a polyacid curing agent. The polyepoxide-polyacid curing agent in the transparent top coat provides a composite coating with outstanding gloss and distinctness of image making the composite coating particularly useful as an automotive top coat.

A color-plus-clear coating system is disclosed. A pigmented or colored base coat is first applied to a substrate followed by the application of a transparent top coat to the base coat. Either the transparent top coat, the base coat or both the top coat and base coat compositions are crosslinkable compositions comprising a polyepoxide and a polyacid curing agent which comprises a half-ester formed from reacting an acid anhydride with a polyol. The polyepoxide-polyacid curing agent in the transparent top coat provides a composite coating with outstanding gloss and distinctness of image making the composite coating particularly useful as an automotive top coat.

Described are photochromic epoxy resin coatings that meet commercially acceptable “cosmetic” standards for optical coatings. Also described are articles having such coatings. The coatings exhibit a Fischer microhardness of from 50 to 150 Newtons per mm2 and desirable photochromic properties, i.e., the formation of darker activated colors and faster rates of photochromic activation and fade when irradiated with ultraviolet light.
