Abstract
A method for planarizing a semiconductor device is provided. The method includes steps hereinafter. A substrate is provided with a first dielectric layer covering at least one electrode structure formed thereon. A chemical-mechanical polishing (CMP) process is performed on the first dielectric layer until the at least one electrode structure is exposed. A second dielectric layer is deposited covering the at least one electrode structure and the first dielectric layer. An etching-back process is performed on the second dielectric layer until the at least one electrode structure is exposed.
