We introduce a level-set strategy to find the geometry of confinement that will guide the self-assembly of block copolymers to a given target design in the context of lithography. The methodology is based on a shape optimization algorithm, where the

We derive functional level-set derivatives for the Hamiltonian arising in self-consistent field theory, which are required to solve free boundary problems in the self-assembly of polymeric systems such as block copolymer melts. In particular, we cons

We introduce a framework for simulating the mesoscale self-assembly of block copolymers in arbitrary confined geometries subject to Neumann boundary conditions. We employ a hybrid finite difference/volume approach to discretize the mean-field equatio

We use self-consistent field theory to investigate the directed self-assembly of cylinder-forming block copolymers for the purpose of a graphoepitaxial pitch multiplication. We focus in particular on conditions where two minor-block cylinders form in

The directed self-assembly (DSA) of block copolymers offers an attractive route to produce one-dimensional rows of cylindrical ∼10 nm scale contact holes for lithography. The success of DSA as a viable lithography technique hinges however on the ab

Directed self-assembly using block copolymers for positioning vertical interconnect access in integrated circuits relies on the proper shape of a confined domain in which polymers will self-assemble into the targeted design. Finding that shape, i.e.,
