Justia Patents US Patent for Imprinting apparatus for producing a member in which a mold contacts a pattern forming layer using alignment control in an in-plane direction of a substrate Patent (Patent # 10,670,961)
Jan 10, 2017 - Canon
An imprint apparatus forms a pattern of an imprint material on a substrate by using a mold, while effecting alignment control of a mold and a substrate with respect to an in-plane direction of the substrate. A mold holding portion holds the mold. A substrate holding portion holds the substrate. A control portion effects control so that the mold and the substrate are brought near to each other while effecting the alignment control, based on a driving profile, after the alignment control is started, to bring the mold and the imprint material into contact with each other. The imprint material is then cured. The control portion changes the driving profile for the alignment control after the alignment control is started and at least one of before and after the mold contacts the imprint material.
