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 1):
A device manufacturing method comprising detecting an alignment mark formed on a substrate, the method further comprising:\n forming a plurality of first patterns and a plurality of second patterns on each of a first position and a second position different from the first position in the substrate, the plurality of first patterns having a first interval between any two adjacent first patterns of the plurality of first patterns, the plurality of second patterns having a second interval between any two adjacent second patterns of the plurality of second patterns, the second interval being different from the first interval; applying a block copolymer to the substrate on which the plurality of first patterns and the plurality of second patterns are formed; applying a self-assembly treatment to the applied block copolymer; forming a first alignment pattern between two adjacent patterns of the plurality of first patterns formed on the first position and/or between two adjacent patterns of the plurality of second patterns formed on the first position and/or forming a second alignment pattern between two adjacent patterns of the plurality of first patterns formed on the second position and/or between two adjacent patterns of the plurality of second patterns formed on the second position using the block copolymer to which the self-assembly treatment has been applied, wherein the detecting of the alignment mark includes detecting, as the alignment mark, the first alignment pattern between two adjacent patterns of the plurality of first patterns formed on the first position and/or between two adjacent patterns of the plurality of second patterns formed on the first position.
