Abstract:
According to one embodiment, an exposure apparatus performs exposure to transcribe a circuit pattern onto each of a plurality of sections on a wafer. The exposure apparatus includes a measurement device and a control device. The control device sets, on each of a first section and a second section adjacent to each other among the plurality of sections, a measurement point at a position offset from a reference position of each section. The control device causes the measurement device to measure surface information at each measurement point. The control device executes focus leveling control for exposure on the basis of the surface information measured at each measurement point.

Claim (Index 8):
A method comprising:\n setting, on each of a first section and a second section adjacent to each other on a wafer, a measurement point at a position offset from a reference position of each section, measuring surface information at each measurement point, and transcribing, by exposure, a circuit pattern onto the first and second sections while executing focus leveling control on the basis of the surface information measured at each measurement point, wherein the setting further includes making a first relative position and a second relative position different from each other, the first relative position being a relative position of a first measurement point with reference to a reference position of the first section, the first measurement point being a measurement point set on the first section, the second relative position being a relative position of a second measurement point with reference to a reference position of the second section, the second measurement point being a measurement point set on the second section, the transcribing includes interpolating first surface information measured at the first measurement point with second surface information measured at the second measurement point, and the executing being executing the focus leveling control for exposure of the first section on the basis of the first surface information which is interpolated with the second surface information.
