Abstract:
A mark forming method includes: exposing a wafer with a mask image to form first and second resist marks that have different shapes than one another based on a portion of the mask image; applying a polymer layer that contains a block copolymer to the wafer by spin-coating; forming self-assembled regions in the applied polymer layer; selectively removing a portion of the self-assembled regions; and forming first and second wafer marks on the wafer using the first and second resist marks. This makes it possible to form the marks when forming circuit patterns using self-assembly of a block copolymer.

Claim (Index 16):
The exposure method according to  claim 15 , wherein\n each of the first and second signal characteristic quantities includes at least one of a contrast of an image signal on a pixel basis, a distance between periodic portions of the image signal, a maximum value and a minimum value of the image signal in a measurement region, and a magnitude of a slope of the image signal.
