Field: Semiconductors (Electrical engineering)
Classification: CPC G  H | IPC G  H

Claim 2:
3. The imprinting apparatus according to claim 1, further comprising:
a third image sensor positioned to detect a fifth alignment mark included in the template and generate a third detection signal of the fifth alignment mark, wherein
the substrate includes a sixth alignment mark, and the non-solidified resin has not yet extended into the third alignment mark at the first timing and the second timing, and
the controller is further configured to:
detect a third timing when the non-solidified resin has extended into the first, second, and third alignment marks, based on the peak of the first detection signal having reached the brightness threshold and the bottom of the first detection signal having reached the darkness threshold, the peak of the second detection signal having reached the brightness threshold and the bottom of the second detection signal having reached the darkness threshold, and a peak of the third detection signal having reached the brightness threshold and a bottom of the third detection signal having reached the darkness threshold, the third timing being after the second timing; and

upon detecting the third timing, terminate the second alignment operation and start a third alignment operation to align the template with the substrate such that the fifth and sixth alignment marks are within a third predetermined deviation.
