  • Publication number: 20140100370
    Abstract: A method of producing an oxidized compound is disclosed. An electric potential is measured of an oxidation reaction solution for producing an oxidized compound by an oxidation reaction, and an end point is determined of the oxidation reaction on the basis of a predefined decrease of the electric potential. Preferably, after the electric potential of the oxidation reaction solution is reached to a highest electric potential, a point is determined where the amount of an electric potential dropped from the highest electric potential reaches the predefined amount of an electric potential as the end point of the oxidation reaction. The method also may introduce an oxidation reaction terminating agent to the oxidation reaction solution immediately after determining the end point of the oxidation reaction.

  • Publication number: 20130286191
    Abstract: In a defect inspecting apparatus, the strength of a fatal defect signal decreases due to miniaturization. Thus, in order to assure a high SN ratio, it is necessary to reduce noises caused by scattered light from a wafer. Roughness of a pattern edge and surface roughness which serve as a scattered-light source are spread over the entire wafer. The present invention has discovered the fact that reduction of an illuminated area is a technique effective for decreasing noises. That is to say, the present invention has discovered the fact that creation of an illuminated area having a spot shape and reduction of the dimension of a spot beam are effective. A plurality of temporally and spatially divided spot beams are radiated to the wafer serving as a sample.

  • Patent number: 8159013
    Abstract: There is provided a layout structure of a semiconductor integrated circuit capable of preventing the thinning of a metal wiring line close to a cell boundary and wire breakage therein without involving increases in the amount of data for OPC correction and OPC process time. In a region interposed between a power supply line and a ground line each placed to extend in a first direction, first and second cells each having a transistor and an intra-cell line each for implementing a circuit function are placed to be adjacent to each other in the first direction. In a boundary portion between the first and second cells, a metal wiring line extending in a second direction orthogonal to the first direction is placed so as not to short-circuit the power supply line and the ground line.

  • Patent number: 7932610
    Abstract: In a semiconductor integrated circuit including a plurality of cells, a supplementary power-supply wire is disposed between a lattice-shaped upper power-supply wire and a lower cell power-supply wire for cases in which power is supplied from the upper power-supply wire to the lower cell power-supply wire. The supplementary power-supply wire and the lower cell power-supply wire are connected by two vias. The supplementary power-supply wire and the upper power-supply wire are connected by a single via. Current from the supplementary power-supply wire is divided by the two vias and then supplied to the lower cell power-supply wire. Therefore, when power is supplied from the upper power-supply wire to the lower cell power-supply wire, current concentration at the connection points of the lower cell power-supply wire to the vias is decreased, thereby reducing wire breaks caused by EM (electro migration).
