Abstract:
According to an embodiment, a first resist pattern that includes a mark including a second pattern provided with first components and a third pattern not provided with the first components is formed. Then, a first recessed area is formed on a processing target layer using the first resist pattern. Thereafter, a second resist pattern that includes a fourth pattern is formed. The fourth pattern is formed such that the third pattern and part of the second pattern, which includes at least one row of the first components arranged along a periphery of the third pattern, are exposed. Then, a second recessed area is formed by using the second resist pattern. Thereafter, a position of the processing target layer is recognized by using a stepped portion formed at the second recessed area, in a light exposure apparatus, and a third resist pattern is formed.

Claim (Index 17):
