A method and apparatus for correcting transparent defects on a photomask are disclosed. A metal-organic complex solution is applied to a transparent defect portion and its periphery on the photomask. The transparent defect portion is then exposed to a visible ray or ultraviolet ray to deposit a metal, a metal oxide or a composition thereof, while the light transmission quantity through the transparent defect portion is measured. After the measurement falls below a predetermined level relative to the quantity of the transmitted light at the start of exposure, the exposure is terminated to thereby complete the correction of the transparent defects.

A method and apparatus for repairing defect portions of a photomask. A complex material from which a light shading material can be deposited is applied over the photomask. A white (blank) defect region is irradiated with a continuous wave laser light beam projected in a slit-like light image to thereby convert the complex material into the shading material. After washing, a half-deposited portion formed in a peripheral portion of the light shading region is further deposited by a post-baking process. Those portions of the light shading film which depart from the desired mask pattern are removed together with black (solid) defect portion originally present in the photomask through irradiation with a pulse laser light beam. The pulse laser is constituted by a Dye-laser, while the continuous wave laser is constituted by an Ar-laser. A specific half-mirror which transmits therethrough Ar-laser light while reflecting Dye-laser light is displaceable provided. The white and the black defects are selectively centered on a same optical axis of an optical projection system including a slit and a condenser lens, whereby the white and the black defect portions are each removed through irradiation with the associated laser light projected thereto in a slit-like light image through the same optical projection system.

Shorting defects between the scan lines and signal lines are repaired during the manufacture of a TFT or other flat panel display unit without causing liquid crystal orientation defects and production yield is thereby improved. In a TFT panel in which scan line 2 bifurcates where scan line 2 and signal line 3 intersect, the lines having a protective insulation film 8 therebetween, one leg of the scan line 2 bifurcation is cut by a laser 9 where a short 7 has been found between lines at the intersection, thereby electrically separating the short. An insulation film material 13 dispensed from a glass pipette 12 is then applied locally to the cut part and surrounding area and cured to form a new insulation film.

When any of pixels is not lit in an organic EL display having an organic EL layer between a first electrode and a second electrode, an organic layer of the pixel is observed. If the organic layer of the pixel contains foreign matter, the second electrode is separated into a region in contact with the foreign matter and a region not in contact with both the contact region and the foreign matter. Thus, not-lit display regions are reduced as less as possible, making it possible to manufacture an organic EL display excellent in display performance.
摘要:
A method and apparatus for inspecting wirings of an electronic circuit substrate to detect a defect in the wiring and for enabling correction thereof. The inspection method and apparatus include electrostatically coupling at least one electrode to a wiring pattern, applying a time varying voltage between the electrode and wiring pattern at different locations so as to detect a current flow and determine a defect by a variation in the detected current flow at the different locations and a portion of the defect. A defect in the form of a disconnected or half-disconnected point of the wiring may be corrected by supplying a solution of a metal complex to the disconnected or half-disconnected point, heating the solution and end point areas of the disconnected or half-disconnected point by laser light and precipitating a metal thin film establishing a connection of the wiring.
