Abstract

According to one embodiment, a pattern forming method includes: forming a guide layer, including a base layer and a neutralization film with a plurality of parallel line sections, on a processing target film, forming a polymer material containing first polymer segments and second polymer segments, on the guide layer, forming a self-assembly pattern having a plurality of first polymer portions containing the first polymer segment and extending in a direction of the line sections, and a plurality of second polymer portions containing the second polymer segment alternating with the first polymer portions and extending along the direction of the line sections, and selectively removing the second polymer portions. The widths of line sections of both ends of the plurality of line sections of the neutralization film are about two times the width of each first polymer portion or each second polymer portion.
