Patent ID: 7670127

Claim:
Apparatus for imprint lithography for transferring a pattern of a structured surface of a template to a target surface of a substrate, comprising a first imprint unit including a first pair of cooperating main parts arranged opposite to one another with an intermediate first spacing and a first press device arranged to adjust the first spacing to transfer a pattern of a structured surface of a template to a receiving polymer surface of a disc in a first imprint step, a second imprint unit including a second pair of cooperating main parts arranged opposite to one another with an intermediate second spacing, and a second press device arranged to adjust the second spacing to imprint the transferred pattern of the disc to a target surface of a substrate in a second imprint step, and a feeder device arranged to move the disc with the transferred pattern from the first spacing to the second spacing wherein a first support frame carries the first pair of cooperating main parts and a second support frame carries the second pair of cooperating main parts, and where a fixation member holds the first and the second support frames in a fixed relation to each other.
