发明名称 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.

主权项 1. A pattern forming method comprising: 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 the first guide layer; 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.
