Method for adjusting electromigration phenomena and power distribution network
By selectively widening the processing area of the target metal conductor in the power distribution network, the electromigration problem of metal interconnects is solved by utilizing the Brechtian effect, thereby improving electromigration resistance and saving costs.

Abstract
This application relates to a method for adjusting electromigration and a power distribution network. The method includes: identifying a target metal wire exhibiting electromigration from among multiple metal wires in the power distribution network, based on preset process data and the load current density of each metal wire; determining the electromigration type corresponding to the contact area between the target metal wire and a connector; determining a region to be treated in the target metal wire based on the electromigration type corresponding to the contact area, the preset process data, and the load current density of the target metal wire; and widening the region to be treated in the target metal wire according to preset size parameters to generate sufficient Bresch effect in the target metal wire to counteract the electromigration phenomenon. This improves the Bresch effect generated in the target metal wire, resulting in better anti-electromigration performance.
