Abstract
A method of design or verification for a self-assemblable block copolymer feature, the block copolymer feature including a first domain having a first polymer type and a second domain having a second polymer type, the method including, based on the length of the second polymer type or on an uncertainty in position of the first domain within the block copolymer feature calculated based on the length of the second polymer type, adjusting a parameter of the self-assembly process of a block copolymer feature or verifying a placement of a block copolymer feature.
