发明名称 Reworked integrated circuit device and reworking method thereof
摘要 Reworking method for removing defects on integrated circuit device is disclosed. An integrated circuit is provided, which has a substrate, a conductive material layer formed in the substrate, a dielectric layer formed on the substrate, at least a contact plug embedded in the dielectric layer, and a conductive layer contacting to the contact plug formed on the dielectric layer. A defect is found in the conductive layer and the reworking method is performed, including an etch back process, a chemical mechanical polishing process, and a deposition process. The reworking method removes the prior formed conductive layer and reform a conductive layer to prevent the integrated circuit from being scraped.
