Publication number: 20240045347Abstract: The throughput is improved by changing a timing of beginning aligning between a mold and a substrate depending on an area in a pattern-forming region where a pattern can be formed. An imprinting method for forming a pattern of an imprint material in a plurality of pattern-forming regions on a substrate using a mold having a pattern portion, having contacting the mold and the imprint material and relatively aligning the mold and the pattern-forming region based on a positional relationship between the mold and an alignment mark of each pattern-forming region, in which, in the aligning, a timing of beginning the aligning is earlier relative to the contacting if an area in the plurality of pattern-forming regions where a pattern can be formed is a second area that is wider than a first area than if an area is the first area.Type: ApplicationFiled: July 18, 2023Publication date: February 8, 2024Inventor: YUJI SAKATA
