| titleOfInvention |
Directed self-assembly process with size-restricted guiding patterns |
| abstract |
A method includes providing a substrate; forming mandrel patterns over the substrate; and forming spacers on sidewalls of the mandrel patterns. The method further includes removing the mandrel patterns, thereby forming trenches that are at least partially surrounded by the spacers. The method further includes depositing a copolymer material in the trenches, wherein the copolymer material is directed self-assembling; and inducing microphase separation within the copolymer material, thereby defining a first constituent polymer surrounded by a second constituent polymer. The mandrel patterns have restricted sizes and a restricted configuration. The first constituent polymer includes cylinders arranged in a rectangular or square array. |
