  • Method for eliminating mask self-magnetization, substrate manufacturing method and mask testing device
    Patent number: 9885104
    Abstract: Disclosed are a method for eliminating self-magnetization of a mask, a method for manufacturing a substrate and a mask testing device. The mask may include a plurality of metal stripes spaced from each other. The method may include a step of: energizing the mask, so as to enable the plurality of metal stripes to carry like charges, thereby separating every metal stripe from other adjacent metal stripes bonded together.
