Process for producing member having pattern, pattern transfer apparatus, and mold

A patterning process comprising the steps of:

• preparing a first mold having a first uneven pattern at a patterning surface thereof;
• preparing a second mold as a peripheral shot mold having a second uneven pattern at a patterning surface thereof;
• providing a wafer comprising a peripheral area along an entire peripheral edge thereof and having a non-peripheral area positioned inside the peripheral area and spaced from the peripheral edge;
• using the first mold to imprint a non-peripheral pattern group positioned completely within the non-peripheral area, the non-peripheral pattern group comprising a plurality of non-peripheral pattern units each corresponding to an individual imprint of the first mold;
• and
• using the second mold to imprint a peripheral pattern positioned completely within the peripheral area, the second mold and peripheral pattern each comprising a shape having straight line segments corresponding to and outlining corners of a plurality of the non-peripheral pattern units and each having a curved line corresponding to the peripheral edge of the wafer,
• wherein the peripheral area is not large enough to imprint an entire non-peripheral pattern unit.
