The scanning exposure apparatus includes a unit configured to correct a relative position between the original and the substrate by a correction amount according to a shifting rate at which the original and the substrate are shifted in synchronization with each other. | 11-20-2008 |
20100002212 | SCANNING EXPOSURE APPARATUS, EXPOSURE METHOD, AND DEVICE MANUFACTURING METHOD - An apparatus includes a control unit configured to control an exposure unit and a driving unit such that exposure of a first region of a substrate starts and ends while a substrate stage is accelerated in a first direction parallel to a scanning direction, an absolute value of maximum acceleration of the substrate stage during a deceleration period is greater than an absolute value during a first approach run period, and a distance by which the substrate stage moves during the first approach run period is approximately equal to a distance by which the substrate stage moves during the deceleration period. | 01-07-2010 |
20130241096 | IMPRINT APPARATUS, AND ARTICLE MANUFACTURING METHOD - An imprint apparatus forms a resin pattern on a substrate by curing resin in a state where the resin on the substrate is in contact with a patterned portion of a mold. It includes: a gas supply unit which supplies gas to a space between the mold and the substrate; a measuring unit which is configured so that measuring light transits the space or a space that communicates with the space, and which measures a prescribed distance between two objects using the measuring light; and a controller which obtains information concerning the prescribed distance, and which outputs a signal representing a state of concentration of the gas in the space based on the information and a measurement result of the measuring unit in a state where the gas is supplied from the gas supply unit. | 09-19-2013 |
20130285270 | TRANSFER APPARATUS AND METHOD OF MANUFACTURING ARTICLE - A transfer apparatus transfers a pattern of an original to a resin on a shot region of a substrate. The original includes a first surface and second surface which are surfaces opposite to each other. The first surface includes a pattern region where the pattern is formed, and the second surface includes a holding surface. The apparatus includes a plurality of holding units configured to hold the holding surface of the original, a plurality of driving units configured to drive the plurality of holding units, respectively, and a control unit configured to control driving of the plurality of holding units by the plurality of driving units to align the pattern region with the shot region of the substrate. | 10-31-2013 |
20140312532 | IMPRINT APPARATUS AND ARTICLE MANUFACTURING METHOD - Provided is an imprint apparatus that imprints a pattern formed on a mold onto a substrate. The imprint apparatus includes a substrate holder that holds the substrate and can move in a direction along the surface of the substrate; a gas supply unit for supplying a gas into a space between a pattern part of the mold and the substrate; and a wall part that is disposed so as to enclose the space that is supplied with gas, wherein at a position opposed to the substrate and the mold, the wall part faces the substrate holder or the substrate with a gap therebetween. | 10-23-2014 |
