Imprinting method and process for producing a member in which a mold contacts a pattern forming layer
An imprinting method in which alignment control of a mold and a substrate is effected and a pattern formed on the mold is transferred onto a pattern forming layer provided on the substrate. The imprinting method includes a step in which the mold and the substrate are brought near to each other while effecting the alignment control, after the alignment control is started, to bring the mold and the pattern forming layer into contact with each other, and then, the pattern forming layer is cured, and a step in which the gap between the mold and the substrate is increased, after the pattern forming layer is cured. Further, the alignment control is stopped after the alignment control is started, and at least one of before and after the mold contacts the pattern forming layer.
METHOD AND APPARATUS FOR EXPOSURE PATTERN CORRECTION AND EXPOSURE SYSTEM
A method for correcting an exposure pattern on a substrate includes obtaining, based on the exposure pattern, displacement adjustment parameters for adjusting displacements of a worktable supporting the substrate in each of a first direction and a second direction, a rotation angle adjustment parameter for adjusting a rotation angle of the worktable in a rotation direction, and a gap adjustment parameter for adjusting a gap between the worktable and a mask plate. The first direction and the second direction are perpendicular to each other in a horizontal plane. The rotation direction is a direction in which the worktable rotates around a central axis of a base table supporting the mask plate. The method further includes moving the worktable based on the displacement adjustment parameters, the rotation angle adjustment parameter and the gap adjustment parameter.
DEPOSITION APPARATUS, MASK FOR DEPOSITION APPARATUS, AND METHOD OF MEASURING GAP BETWEEN MASK FOR DEPOSITION APPARATUS AND SUBSTRATE
A deposition apparatus includes a substrate, a mask disposed on a first surface of the substrate and including a mask frame supporting an edge area of the substrate, a through-hole formed in the mask frame along the edge area of the substrate, a measurement member disposed between the substrate and the mask frame at a position corresponding to the through-hole and including a measurement hole connected to the through-hole and a measurement camera disposed on a first surface of the mask frame at the position corresponding to the through-hole, wherein the measurement camera measures a first distance to the measurement member exposed through the through-hole and a second distance to the substrate exposed through the measurement hole.
