摘要:
The present invention discloses in detail a semiconductor device and a patterning method for the plated electrode thereof. By using the laser ablation method according to the prior art, the semiconductor substrate below the ARC is damaged by direct destructive burning. According to the present invention, an additional protection layer is inserted between the ARC and the semiconductor substrate. Then a laser is used for heating and liquefying the protection layer below the ARC, and thus separating the ARC from the liquefied protection layer underneath and forming pattered openings. Afterwards, by a plating process, nickel and copper can plated.

A membrane reactor with divergent-flow channel includes a reaction pipeline, a membrane and a purge (sweep) pipeline sequentially arranged from inside to outside or from outside to inside. The reaction pipeline has a cross-sectional area increment from the front (upstream) end to the rear (downstream) end, so that the flow velocity of a reactant gas is decreased from the upstream end to the downstream end to extend the residence time of the reactant gas and improve the reaction rate of the reactant gas. The sweep pipeline has a cross-sectional area decrement from the upstream end to the downstream end, so that the flow velocity of a purging (sweeping) gas is increased from the upstream end to the downstream end to accelerate the reactant gas, and a product gas generated from the reaction passes through the membrane and enters the sweep pipeline to improve the reaction efficiency.

The present invention provides a membrane reaction apparatus for recovering heat of reaction, which includes a membrane reactor. The said membrane reactor includes a reaction pipeline, a membrane and a sweep pipeline. The reaction pipeline has a reaction space, and an exothermic reaction occurs therein, which generates product gas and heat of reaction. Part of the product gas penetrates through the membrane around the reaction space and enters into the sweep pipeline. Sweeping gas enters into the sweep pipeline and carries the product gas and the heat of reaction away. It is feasible to wrap the product gas around the sweep pipeline, for enhancing the heat transfer from the product gas to the sweeping gas. The heat of reaction brought by the sweeping gas can be further released in a heat exchanger. so that the heat of reaction is available to be recovered and used for other endothermic processes.

A method for manufacturing membrane layers of organic solar cells by roll to roll coating utilizes a roll to roll process for manufacturing an electron transferring layer and an active layer of the organic solar cells is disclosed. The roll to roll process adopted by the method cooperates with a particular solvent and accompanies a parameter control such as temperature and processing time during the sintering and baking steps. The method utilizes a slot-die coating technique in the interim, whereby a membrane layer of the solar cells can be manufactured with a large area for reducing the cost, and the formed membrane layers can have a good efficiency.

The present invention relates to a preparation method for patternization of metal electrodes in silicon solar cells. After disposing an amorphous silicon layer on a silicon substrate processed by diffusion, laser light is projected on the amorphous silicon layer for patternization, and transforming the amorphous silicon with low optical conductivity into polysilicon with high optical conductivity thanks to the recrystallization process of the laser light. Then, after immersing the amorphous silicon layer in plating liquid, metal electrode can be formed accurately at the spots of the amorphous silicon layer patterned by laser light. No external voltage is required; plating reaction is induced by illumination directly.

A novel synthesis method of Glyco-drug radiotracer precursor is revealed. After completing synthesis of Z-Gly-ah (main structure), galactosamine GalNAc(OAc)4 is added to have coupling reaction. Then a product is separated directly from dichloromethane. Thus loss of galactosamine during extraction with liquid chromatography is reduced. Moreover, instead of trifluoroacetyl group, carbobenzoxy (abbreviated as Cbz or Z) is used as a protecting group to ensure uniformity of the phase. The cost and synthesis time are also dramatically reduced.

The shape of the solid oxide fuel cell is planar or tubular.

A nanostructured anode of solid oxide fuel cell with high stability and high efficiency and a method for manufacturing the same are revealed. This anode comprising a porous permeable metal substrate, a diffusion barrier layer and a nano-composite film is formed by atmospheric plasma spray. The nano-composite film includes a plurality of metal nanoparticles, a plurality of metal oxide nanoparticles, and a plurality of gas pores that are connected to form nano gas channels. The metal nanoparticles are connected to form a 3-dimensional network that conducts electrons, while the metal oxide nanoparticles are connected to form a 3-dimensional network that conducts oxygen ions. The network formed by metal oxide nanoparticles has certain strength to separate metal nanoparticles and prevent aggregation or agglomeration of the metal nanoparticles. Thus this anode can be applied to a solid oxide fuel cell operating in the intermediate temperatures (600˜800° C.) with high stability and high efficiency.
