Light-transmitting imprinting mold and method for manufacturing large-area mold

A light-transmitting imprint mold, comprising:

• a transparent substrate having a patterned region onto which a concave-convex pattern is formed;
• and
• a light shielding member provided on the patterned region;
• wherein
• the light shielding member is provided at an edge portion of the patterned region so as to cover the concave-convex pattern, both of a concave portion and a convex portion of the concave-convex pattern being continuously covered;
• and
• a surface profile of the light shielding member reproduces the concave-convex pattern.

An imprint method comprising the steps of:

• an exposing step to irradiate a photo curing resin, coated on a large-area substrate, with a curing light while the light-transmitting imprint mold is pressed against the photo curing resin, an amount of the curing light applied onto the photo curing resin in a light shielding region provided with the light shielding member being less than an amount of the curing light applied onto the photo curing resin in a light transmitting region of the mold so that a portion of the photo curing resin in the light shielding region is semi-cured;
• a separating step to separate the mold from the photo curing resin after the exposing step;
• a moving step to move the mold so that an end of the light transmitting region of the mold is positioned on the semi-cured portion of the photo curing resin;
• and
• a repeating step to repeat the exposing step and the separating step with the mold positioned at a position after the moving step.
