摘要: A method for fabricating a first electrode of a capacitor is described. A substrate comprising an insulating layer formed thereon is provided. The insulating layer has an opening. A silicon layer is formed on the insulating layer. The silicon layer is transformed to a hemispherical grain layer. An etching process is performed to remove a portion of the hemispherical grain layer outside the opening.
