摘要:
An object is to provide an SOI substrate with excellent characteristics even in the case where a single crystal semiconductor substrate having crystal defects is used. Another object is to provide a semiconductor device using such an SOI substrate. A single crystal semiconductor layer is formed by an epitaxial growth method over a surface of a single crystal semiconductor substrate. The single crystal semiconductor layer is subjected to first thermal oxidation treatment to form a first oxide film. A surface of the first oxide film is irradiated with ions, whereby the ions are introduced to the single crystal semiconductor layer. The single crystal semiconductor layer and a base substrate are bonded with the first oxide film interposed therebetween. The single crystal semiconductor layer is divided at a region where the ions are introduced by performing thermal treatment, so that the single crystal semiconductor layer is partly left over the base substrate. The single crystal semiconductor layer left over the base substrate is irradiated with laser light. The single crystal semiconductor layer left over the base substrate is subjected to second thermal oxidation treatment to form a second oxide film. Then, the second oxide film is removed.

摘要:
A heat exchanger 32 comprises a first heat exchanger 40 for allowing heat to be exchanged between water and a reformed gas from a reforming reactor, a second heat exchanger 50 for spraying and vaporizing water in the reformed gas from the first heat exchanger 40, and a third heat exchanger 60 for vaporizing unvaporized or precipitated water. The reformed gas from the reforming reactor is cooled by the heating and vaporizing of water, and is mixed with the vaporized water and fed as mixed gas to a water gas shift reactor. The processes of cooling the reformed gas, heating and vaporizing of the water, and mixing the reformed gas and steam are completed in the heat exchanger 32, making it possible to design a smaller, simpler, and more efficient apparatus.
摘要:
Mists atomized from siphon type two-fluid nozzles 14a and 14b are made to collide with each other within a secondary gas intake conduit 16 and secondary gas is supplied toward a collision point of the mists. A flow control plate 22 is provided within the secondary gas intake conduit 16 at a point upstream from the collision point to ensure that the secondary gas does not interfere with the collision of the mists and also to promote fine mists generated by the collision of the mists to mix with the secondary gas. Further, a secondary nozzle 24 is provided at the tip of the secondary gas intake conduit 16 to jet the secondary gas including the fine mists from the secondary nozzle 24. In the case of applying this mist atomizer 10 to the fuel cell 30, droplets and liquid water in the process gas is separated and removed at the mounting portion of the mist atomizer 10 in order to selectively supply mist of equal-sized particles only into the fuel cell. The collected water is stored in the supply water tank temporarily and supplied again to the two-fluid nozzle for reuse.
