Abstract
A micro-pattern element has a heat discharge pattern formed on a fine line portion of a conductor pattern. Breakage caused by temperature elevation of the conductor pattern in response to the application of an electric current and resulting electromigration can be effectively prevented by the heat-discharge pattern formed on the fine line portion of the conductor pattern; thus, the reliability of the micro-pattern element can be remarkably improved.
