    摘要： A method of determining an uncertainty in the position of a domain within a self-assembly block copolymer (BCP) feature. The method includes simulating a BCP feature, calculating a minimum energy position of a first domain within the simulated BCP feature, simulating the application of a potential that causes the position of the first domain to be displaced from the minimum energy position, simulating release of the potential back toward the minimum energy, recording a plurality of energies of the BCP feature during the release and recording at each of the plurality of energies a displacement of the first domain from the minimum energy position, calculating, from the recorded energies and recorded displacements, a probability distribution indicating a probability of the first domain being displaced from the minimum energy position, and, from the probability distribution, calculating an uncertainty in the position of the first domain within the BCP feature.

    摘要： A method of forming a plurality of regularly spaced lithography features, the method including providing a self-assemblable block copolymer having first and second blocks in a plurality of trenches on a substrate, each trench including opposing side-walls and a base, with the side-walls having a width therebetween, wherein a first trench has a greater width than a second trench; causing the self-assemblable block copolymer to self-assemble into an ordered layer in each trench, the layer having a first domain of the first block alternating with a second domain of the second block, wherein the first and second trenches have the same number of each respective domain; and selectively removing the first domain to form regularly spaced rows of lithography features having the second domain along each trench, wherein the pitch of the features in the first trench is greater than the pitch of the features in the second trench.
