Disclosed are a method and a device for repairing a circuit on an array substrate, and an array substrate. The method includes: determining a section to be repaired on each signal line; applying a conductive material to form a repair line between two ends of the section to be repaired, the repair line being connected with two ends of the section to be repaired; and applying an insulating material to form a cover layer above the repair line, the cover layer completely covers the surface of the repair line.

Provided is a method of fabricating a package structure including: forming a first bonding layer over a first surface of a first die; forming a release structure over a first carrier; bonding the first die to the first carrier by contacting the first bonding layer with the release structure; performing a laser process to divide the release structure into a first portion and a second portion, thereby debonding the first carrier from the first die; and performing a first removal process on the first portion of the release structure over the first carrier to expose a surface of the first carrier. The cleaned first carrier can be reused to fabricate another package structure, thereby reducing manufacturing costs and be greener or more environmentally friendly.

A method of fabricating an electronic component includes: controlling a laser cutting tool at a first pulse rate to form a first cut portion in a feature of the electronic component, the feature having opposite first and second sides spaced apart from one another along a first direction, and third and fourth sides spaced apart from one another along a second direction, the first cut portion extending from the third side toward the fourth side; controlling the laser cutting tool at a higher second pulse rate and to form a second cut portion extending from the first cut portion toward the fourth side; and controlling the laser cutting tool at a third pulse rate to form a final cut portion extending from the second cut portion toward the fourth side, the third pulse rate less than the second pulse rate.
