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 1):
An exposure apparatus that performs exposure to transcribe a circuit pattern onto each of a plurality of sections on a wafer, the exposure apparatus comprising:\n a measurement device; and a control device that 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, causes the measurement device to measure surface information at each measurement point, and executes focus leveling control for exposure on the basis of the surface information measured at each measurement point, wherein the control device makes 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, wherein the control device executes the focus leveling control for exposure of the first section on the basis of surface information measured at the first measurement point and surface information measured at the second measurement point, wherein the control device executes the focus leveling control for the exposure of the first section by using the surface information measured at the second measurement point as surface information measured at a position offset from the reference position of the first section by an offset amount of the second measurement point.
