Abstract: A guiding pattern for directed self-assembly (DSA) of a block copolymer (BCP) is an array of spaced guiding stripes on a substrate that have a width equal to nL0 and a pitch equal to (n+k)L0, where n and k are integers equal to or greater than 1 and L0 is the natural pitch of the BCP. The guiding stripes have oxidized sidewalls. A silicon-containing BCP self-assembles with the BCP component without silicon wetting the oxidized sidewalls. Then oxygen reactive ion etching (RIE) removes the BCP component without silicon and oxidizes the silicon-containing BCP component. The remaining pattern of silicon oxide containing BCP component can then be used as an etch mask to etch the underlying substrate.

Abstract: A method for directed self-assembly (DSA) of block copolymers (BCPs) uses a BCP blend with a small portion of functional homopolymers, called “inks”, before deposition and annealing of the BCP. A substrate has a patterned sublayer formed on it. The BCP blend is deposited on the patterned sublayer and annealed. The BCP blend is guided by the sublayer pattern. The inks selectively distribute into blocks, and part of the inks graft on the substrate underneath the blocks. The BCP blend layer is rinsed away, leaving the grafted inks. The grafted inks form a chemical contrast pattern that has the same geometry with the BCP bulk morphology. This process is repeated, which results in the grafted inks forming a thicker and denser chemical contrast pattern. This chemical contrast pattern of grafted inks is used for the DSA of a BCP that self-assembles as lamellae perpendicular to the substrate.

Abstract: In directed self-assembly (DSA) of a block copolymer (BCP), a patterned sublayer on a substrate serves as a guiding chemical prepattern on which BCPs form more uniform and/or denser patterns. A layer of a blend of a BCP and functional homopolymers, referred to as inks, is deposited on the patterned sublayer and annealed to change the initial chemical prepattern to a 1:1-like chemical pattern that is more favorable to DSA. After annealing, the inks selectively distribute into blocks by DSA, and part of the inks graft on the substrate underneath the blocks. The BCP blend layer is then rinsed away, leaving the grafted inks. A second layer of BCP is then deposited and annealed as a second DSA step to form alternating lines of the BCP components. One of the BCP components is removed, leaving lines of the other BCP component as a mask for patterning the substrate.
