Abstract:
The present disclosure relates to a method for pattern formation on a substrate. An example embodiment includes a method for pattern formation. The method includes providing a photoresist layer on a composite substrate. The method also includes patterning the photoresist layer by lithography to define a plurality of parallel stripe photoresist structures. The method further includes providing a block copolymer on and along the composite substrate, in between the parallel stripe photoresist structures. The block copolymer includes a first component and a second component. The method additionally includes subjecting the block copolymer to predetermined conditions to cause phase separation of the first component and the second component. In addition, the method includes performing a sequential infiltration synthesis process. Still further, the method includes selectively removing the parallel stripe photoresist structures. Additionally, the method includes defining a core stripe structure. Even further, the method includes performing a self-aligned multiple patterning process.
