Method of forming metal lines and bumps for semiconductor devices

摘要

Provided is a method of forming conductors (e.g., metal lines and/or bumps) for semiconductor devices and conductors formed from the same. First and second seed metal layers may be formed. At least one mask may be formed on a portion on which a conductor is to be formed. An exposed portion may be oxidized. The oxidized portion may be removed. A conductive structure may be formed on an upper surface of a portion which is not oxidized. The conductors may be metal lines and/or bumps. The conductive structures may be solder balls.
