Claim:
A method for transferring a pattern to an object, comprising the steps of: forming a first photoresist layer over the object, said first photoresist layer being made of a first material; forming an alignment mark from said first photoresist layer by removing a portion other than an alignment mark forming portion of said first photoresist layer, the alignment mark being made of the alignment mark forming portion of the first photoresist layer; forming a second photoresist layer over the object so as to cover said alignment mark, said second photoresist layer being made of a second material that is different from the first material; patterning said second photoresist layer on the basis of said alignment mark; transferring a pattern of the second photoresist layer into a surface of the object; and removing said second photoresist layer and said alignment mark; wherein a pattern of the alignment mark is not transferred into the surface of the object.
