A first semiconductor chip is mounted on the substrate surface. The first semiconductor chip has a second height that is less than the first height. The first semiconductor chip can be connected to the substrate with bonding wires or the like. A second semiconductor chip is mounted on the spacers and spans the distance between the spacers. The second semiconductor chip is above at least a portion of the first semiconductor chip. A projecting section is provided on the surface of the substrate between the spacers in the first direction.

Abstract: While green algae are expected to serve as raw materials of biomass fuels, they are damaged by high-intensity light when subjected to mass-culture outdoors in summer, and biomass productivity is deteriorated as a consequence. In order to overcome such a drawback, the present invention provides a high-intensity light resistant green algae mutant that can be subjected to outdoor culture in summer. Specifically, the present invention relates to such green algae mutant, wherein functions or expression levels of a protein having a response regulatory domain at the N-terminus and a WD40 domain at the C-terminus are lower than those in a wild-type strain, and wherein said green algae mutant grows faster than a wild-type strain when cultured at a light intensity of 1,000, 1,500, or 2,000 ?mol photons m?2 s?1 measured as photosynthetically active radiation (PAR).

Abstract: A noble metal adsorption agent includes algae or residue of algae having an amino group as a functional group. A noble metal is retrieved by a method including: adsorbing the noble metal on the noble metal adsorption agent; and retrieving the noble metal. The noble metal is solved in a liquid. Thus, by using the noble metal adsorption agent, the noble metal is selectively retrieved.

Abstract: The object of the present invention is to provide a method for aggregating and separating algae dispersed in a liquid efficiently. According to the present invention, a method for aggregating and separating algae dispersed in a liquid, which comprises adding an alkaline inorganic aggregating agent to the liquid at pH of 2.0 to 4.0 in which algae are dispersed, followed by adding a cationic polymer aggregating agent, is provided. Further, according to the present invention, a method for producing biofuel utilizing algae is provided.

Abstract: An adsorbent contains a carbohydrate having an ether linkage. Alternatively, an adsorbent contains a carbohydrate having a cross-linkage formation produced by a dehydration reaction using a strong acid. In collection of a precious metal using the adsorbent, the adsorbent selectively adsorbs a precious metal dissolved in a solution.

Abstract: A semiconductor memory device includes memory cells, source lines, drain lines, and control gate lines. The memory cells are arranged in matrix. Adjacent memory cells in the column direction have one of a source and a drain in common. The sources of memory cells of adjacent two columns are connected to a common source line. The drains of memory cells of adjacent two columns are connected to a common drain line. The drains of memory cells of two columns connected to the source line are connected to different drain lines, respectively. The gates of adjacent memory cells in the row direction are connected to a common control gate line.

Abstract: There is disclosed a memory cell which has a diffusion layers constituting source/drain areas formed on a p-type silicon substrate surface, and a channel area formed between the diffusion layers. Above the channel area, an insulating film of a laminated structure is formed of a silicon oxide film, a silicon nitride film and a silicon oxide film. A gate electrode is formed on the upper surface of the insulating film of the laminated structure. The gate electrode is used as a word line. Moreover, an interlayer insulating film is formed between the diffusion layer and the gate electrode. By injecting hot electrons from the substrate to the silicon nitride film in the insulating film of the laminated structure, data is written. The silicon nitride film and the diffusion layer are partially overlapped in a vertical direction, and an offset portion is disposed between the silicon nitride film and the diffusion layer.
