Pattern forming method |
摘要 |
According to one embodiment, a pattern forming method includes forming a first guide layer on a processed film, phase-separating a first self-assembly material with the use of the first guide layer to form a first self-assembly pattern including a first polymer portion and a second polymer portion, selectively removing the first polymer portion, forming a second guide layer with the use of the second polymer portion, and phase-separating a second self-assembly material with the use of the second guide layer to form a second self-assembly pattern including a third polymer portion and a fourth polymer portion. |
