  • Publication number: 20220067902
    Abstract: The purpose of the present invention is to provide an image evaluation device and method which can detect unknown defects and which can prevent misrecognition by a machine learning model. This image evaluation device, which uses a machine learning classifier to classify defect information in a defect image of an electronic device, is characterized by being provided with: an image storage unit which stores a defect image of an electronic device; a defect region storage unit which stores defect region information that is in the defect image; a classifier which classifies the defect information with machine learning; an image extraction unit which, in the course of the defect image classification processing, extracts image-of-interest information which the classifier will focus on; and an evaluation unit which compares the image-of-interest information and the defect region information to evaluate the classifiability of the defect image.

  • Patent number: 8309471
    Abstract: A layer to be etched is first formed in a substrate. Then, a mask pattern is formed over the layer to be etched. Then, the layer to be etched is wet-etched using the mask pattern as a mask. In the procedure of performing wet etching, the substrate is dipped into an etching bath with the mask pattern downward.

  • Publication number: 20110059606
    Abstract: A photosensitive resin film is formed on a protective insulating film. Next, a plurality of bump cores is formed on the protective insulating film along a first straight line by exposing and developing the photosensitive resin film. Next, a plurality of bumps, and a plurality of interconnects that connects each of the plurality of bumps to any of the electrode pads are formed by selectively forming conductive films on a plurality of bump cores, a plurality of electrode pads, and the protective insulating film. In the step of forming a plurality of bump cores, a region bordering on the interconnect on the lateral faces of the bump core is formed to have a gentler slope than that of a region intersecting the first straight line, by exposing the photosensitive resin film only one time using a multi-gradation mask.
