  • Method of correcting defect of patterned article
    Patent number: 4931307
    Abstract: A method of correcting a missing defect of a patterned film formed on an icle is carried out by steps of providing an operative vacuum chamber having a pin hole, positioning an area of the missing defect outside the vacuum chamber in registration with the pin hole, operating the vacuum chamber to cause therein cold cathode discharging to generate particles, and directing a stream of the particles through the pin hole onto the area of the missing defect to deposit thereon a corrective film of the particles.
