摘要: A defective part recognition device includes a microscope for obtaining a magnified image of a unit area for recognizing a defective part on the surface of a multi-layer film substrate; a spectral camera having an imaging surface where the magnified image is formed; and an information processing part for processing the spectrum information from the spectral camera. The information processing part includes a machine learning part for a clustering process on the spectrum information for each pixel, and a defect recognition part for recognizing a defective part from the result of the machine learning part. The machine learning part sets a cluster in the unit area and generates a histogram with a frequency, the number of pixels clustered into the cluster. The defect recognition part compares the frequency distribution of the generated histogram with that of a histogram free of defects and recognizes a defective part.

摘要: Even in the case where an underlayer differs or a film thickness varies, high-quality repair is allowed to be performed.
When a laser repair method performs repair work by setting a laser irradiation area for a defect part of a multi-layer film substrate and irradiating the defect part with a laser beam under a set laser working condition, the laser repair method includes: identifying a peripheral region of a laser beam irradiation position; dividing the identified peripheral region into a plurality of divided regions for each common reflected light information; inferring a layer structure at the laser beam irradiation position from analogy based on an arrangement pattern of the divided regions positioned around the laser beam irradiation position; and setting the laser working condition of the laser beam to be emitted based on the layer structure inferred from analogy.-

摘要: A substrate mounting method of an electronic component on a wiring substrate includes steps of patterning to form a conductive elastic protrusion on an electrode pad provided on the wiring substrate to correspond to a contact point of the electronic component, forming an adhesive layer made of a photosensitive thermosetting resin on the wiring substrate, lowering viscosity of the adhesive layer by heating the adhesive layer to a first temperature zone, electrically connecting the contact point of the electronic component to the electrode pad on the wiring substrate through the conductive elastic protrusion, under a state where the viscosity of the adhesive layer is lowered, by pressing the electronic component after the electronic component is positioned on the wiring substrate, and fixing the electronic component onto the wiring substrate by heating the adhesive layer to a second temperature zone higher than the first temperature zone to cure the adhesive layer.

摘要: A photo-aligning exposure device that performs a photo-aligning process by performing scanning exposure on an irradiated plane in one direction includes: a light source that emits scattering light toward the irradiated plane; an optical filter that selectively emits an ultraviolet ray out of the light emitted from the light source; and an irradiation angle restriction member that selectively emits light with which irradiation is diagonally performed with respect to the scanning direction out of the light emitted from the optical filter. The irradiation angle restriction member has a plurality of flat-plate-shaped light direction restriction plates slanted at a certain angle with respect to the irradiated plane and arrayed in parallel along the scanning direction at a predetermined distance.
