Abstract:
1. A nano-imprinting process, comprising: providing a substrate including an imprinting material layer covering a surface of the substrate; providing a mold including a plurality of protruding features and at least one indentation set on a surface of the mold, wherein the indentation is disposed between the protruding features, and the surface of the mold is covered with an anti-adhesion layer; forming a transferring material layer on a top surface of each protruding feature; pressing the surface of the mold into the imprinting material layer to make the transferring material layer embed in a first portion of the imprinting material layer and not contact the substrate; removing the mold and separating the mold and the transferring material layer simultaneously to transfer the transferring material layer into the first portion of the imprinting material layer and to reveal a second portion of the imprinting material layer; using the transferring material layer as a mask to remove the second portion of the imprinting material layer and a portion of the substrate underlying the second portion of the imprinting material layer; and removing the first portion of the imprinting material layer and the transferring material layer.
