  • Patent number: 10558127
    Abstract: The purpose of the present invention is to provide an exposure condition evaluation device that appropriately evaluates a wafer exposure condition or calculates an appropriate exposure condition, on the basis of information obtained from an FEM wafer, without relying on the formation state of the FEM wafer. In order to achieve the foregoing, the present invention proposes an exposure condition evaluation device which evaluates an exposure condition of a reduction projection exposure device, on the basis of the information of patterns exposed on a sample by the reduction projection exposure device, and which uses a second feature amount of a plurality of patterns formed by making exposure conditions uniform to correct a first feature amount of a plurality of patterns formed by a plurality of different exposure condition settings.

  • Patent number: 10176720
    Abstract: An auto driving control system includes: a situation determining unit which recognizes a situation around the vehicle and determines whether automatic traveling is possible; a drive control unit which performs traveling control when the automatic traveling is possible; a state determining unit which determines whether an occupant is able to drive; and an estimation drive control unit configured such that when the automatic traveling is difficult and it is difficult for the occupant to take over the driving, and when it is determined that execution of a function of the automatic traveling is difficult due to a first sensor, the estimation drive control unit executes the function by using information of a second sensor, and performs traveling control of the vehicle, wherein the automatic traveling is continued based on a control instruction of the estimation drive control unit until the occupant becomes able to take over the driving.

  • Patent number: 9141879
    Abstract: In order to provide a computer program, an image processing device, and a pattern matching method that perform pattern matching at a high level of accuracy without relying on edge deformation, contrast fluctuations, etc., in one embodiment, the disclosed pattern matching method and device perform pattern matching over an image using a template produced on the basis of the below mentioned design data. The pattern matching method and device determine the characteristic quantities of the image for an inner region and/or an outer region that are divided by a line that defines the contour of a pattern, and determine positions at which said characteristic quantities satisfy predetermined conditions to be matching positions, matching position candidates, or erroneous matching positions.
