  • Publication number: 20090230984
    Abstract: For adjusting a positional relationship between a specimen and a probe to measure an electric characteristic of the specimen through a contact therebetween, a base table holding a specimen table holding the specimen and a probe holder holding the probe is positioned at a first position to measure the positional relationship between the probe and the specimen at the first position, and subsequently positioned at a second position to measure the positional relationship therebetween at the second position so that the probe and the specimen are contact each other at the second position, the specimen table and the probe holder are movable with respect to each other on the base table at each of the first and second positions to adjust the positional relationship between the probe and the specimen, and a measuring accuracy at the second position is superior to a measuring accuracy at the first position.

  • Publication number: 20080158575
    Abstract: There is provided a variable data image generating device including a plurality of first type image generating units that execute a first rendering instruction for a distributed record and generates a first type image corresponding to the record; a first type image memory that stores the first type image corresponding to each record generated by each of the first image generating units; a distributing unit that distributes a record in variable data to each of the first type image generating units; and a document image generating unit that executes a drawing program including one or more instructions for each record in the variable data, wherein the document image generating unit generates a document image for each record by obtaining the first type image corresponding to the record from the first type image memory and laying out the obtained image in response to the first rendering instruction in the rendering program.

  • Patent number: 7095074
    Abstract: Defects in element forming regions on which memory cells of a non-volatile memory are formed are to be diminished to reduce leakage current. End portions of element forming regions with non-volatile memory cells formed thereon are extended a length D by utilizing the region which underlies a dummy conductive film, whereby a stress induced from an insulating film which surrounds the element forming regions is concentrated on the extended region. As a result, defects do not extend up to the regions where memory cells are formed and therefore it is possible to reduce leakage current in the memory cells.

  • Patent number: 6808951
    Abstract: An insulating film for protecting an upper portion of a control gate electrode is constituted by a silicon oxide film, and thereby stress affecting a gate oxide film and a substrate that is located below a bottom portion thereof is reduced. Further, an etching prevention film consisting of a silicon nitride film is formed on a sidewall of the silicon oxide film, and thereby it is possible to prevent the sidewall of the silicon oxide film from being etched in a hydrofluoric acid cleaning step after processing of a gate electrode.
