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 15):
The exposure apparatus according to  claim 1 , wherein\n the measurement device includes a projection system and a detection system each including a grating with openings, the openings are spaced evenly in a first direction, each measurement point includes a plurality of third measurement points spaced evenly in a second direction, luminous fluxes applied through the openings of the grating of the projection system are applied to the plurality of third measurement points, and the detection system receives the luminous fluxes reflected at the plurality of third measurement points through the openings of the grating of the detection system, and acquires surface information regarding the plurality of third measurement points.
