In the method, a nickel film and a nickel oxide film are laminated in this order on a surface of an n-type silicon carbide substrate or an n-type silicon carbide region of a silicon carbide substrate, followed by a heat treatment under a non-oxidizing condition. The heat treatment transforms a portion of the nickel film into a nickel silicide film. Then, the nickel oxide film is removed with hydrochloric acid solution, and subsequently, a nickel aluminum film and an aluminum film are laminated in this order on a surface of the nickel silicide film. | 02-19-2009 |

Second connecting trench extends at 30 degrees of angle with the extension of first straight trench. Third connecting trench extends at 30 degrees of angle with the extension of second straight trench. A manufacturing method according to the invention for manufacturing a silicon carbide semiconductor device facilitates preventing defects from being causes in a silicon carbide semiconductor device during the manufacture thereof. | 07-29-2010 |
| 20110070723 | METHOD OF MANUFACTURING A SILICON CARBIDE SEMICONDUCTOR DEVICE - A method of manufacturing a silicon carbide semiconductor device is disclosed in which a trench and a hole are controlled to have a predetermined configuration even if the silicon carbide semiconductor device is subjected to a heat treatment at a temperature of not lower than 1,500° C. A heat treatment step(s) of a method of the invention includes a step of heat treatment in an argon atmosphere at a temperature in a range of 1,600° C. to 1,800° C. under a pressure of at most 10 Torr for a time duration in a range of 0.1 min to 10 min to evaporate silicon atoms from a surface of the silicon carbide semiconductor substrate or the silicon carbide epitaxial layer and to obtain a silicon carbide surface with a carbon atom concentration of at least 95%. The method can further comprise a step of ion implantation of nitrogen ions or phosphorus ions in a dose amount of 8×10 | 03-24-2011 |

| 20100258627 | CONFIGURATION INFORMATION COMPLEMENTING TRACEABILITY SYSTEM - In traceability system applications, it is required to check relationships between individual articles under management and containers therefor such as container cases or pallets. Since relevant data in each stage of physical distribution is not always registered, the absence of some necessary data may occur to cause inaccurate commodity tracing. To solve this disadvantage, the present invention provides a traceability system capable of complementing information regardless of time-series factors. Even in a situation where a plurality of sets of information (relational data) regarding packing-unpacking relationships between articles and containers, e.g., relationships between commodity products and packing cases, or relationships between packing cases and pallets, are not registered in time-series order, the relational data are complemented in registration to enable complementary estimation from registered information available at the time of reference. | 10-14-2010 |
| 20100302036 | IC TAG ISSUE MANAGEMENT SYSTEM AND METHOD - An IC tag issue management system includes an ID numbering DB which stores an ID and a status of the ID, and an ID history DB which stores the ID, a history number indicating a reuse history of the ID, and a usage history indicated by the history number correlated with each other with each other. The IC tag issue management system numbers the ID with the usage history having a time elapsing from a starting date of the usage history in which the end date is not stored in the ID history DB passing over a predetermined ID-non-reusable period in response to a request for numbering the ID to be written into the IC tag when the unnumbered ID which has not been allocated to the IC tag, and the ID having the status of the ID numbering DB set in the “unused” status do not exist. | 12-02-2010 |
| 20100321167 | INDIVIDUAL-ITEM INFORMATION MANAGEMENT DEVICE AND METHOD - In an assembled product, a decrease in reading efficiency is avoided from being deteriorated by reading the electronic tags of the parts and the assembled product, registering their configuration information, and by placing read restriction on the electronic tags of the parts. For this purpose, manufacturing instruction information, used for assembling parts into an assembled product, is used. When replaced, the electronic tags of the assembled product are read, read restriction is removed from the assembled product, the electronic tag is read, the electronic tag of a new part to be installed is read, read restriction is placed on the electronic tag, and the configuration information is updated. An invalid part replacement is detected by comparing the configuration information. | 12-23-2010 |
| 20110087612 | PRODUCT DELIVERY SYSTEM - A sensor device for detecting product quality conditions is attached to each product to be delivered, and constant monitoring is performed on quality conditions of stock products in a storage room of a delivery center for quality assurance. For products in a storage room of a delivery truck, constant monitoring is also performed on quality conditions thereof in the same manner. If a quality abnormality is found in a product in the storage room, information regarding product sensing items and information regarding the current location of each delivery truck are processed to select a replacement stock product less susceptible to recurrence of a similar quality abnormality at the time of redelivery. | 04-14-2011 |
