CONSTITUTION: An alignment key is provided with the first alignment key(42) and the second alignment key(46). The first alignment key(42) as a lower metal pattern is formed by depositing a conductive metal film on a scribe line of a semiconductor substrate(40) and patterning the conductive metal film. After forming an interlayer dielectric(44) on the resultant structure, the second alignment key(46) having bar-shaped groove structure is formed at upper edge portions of the first alignment key(42) by patterning the interlayer dielectric.
