Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] Such as figure 1 In the process shown, the substrate (3) is evenly covered with a transfer medium (31), here is a photoresist. The obtained imprint template (2) is brought into contact with the substrate (3), so that the transfer medium (31) is evenly transferred from the substrate (3) to the imprint template (2). The transfer medium (21) on the embossing template is rolled onto the bar (1), so as to realize the transfer of graphics. Then the rod (1) is etched, here, the etching solution (4) is put in, and the etching depth is controlled. Finally a final bar (5) is obtained which contains microstructures (51) on the bar. After the template is cleaned up, the next production can be carried out.

[0029] See figure 1 — Figure 5 , the present invention is a microstructure roll forming manufacturing method on a curved surface, the sp...

Abstract

The invention discloses a rolling-forming manufacturing method for a microstructure on a curved surface. The method comprises six steps. A template is rolled on the outer surface of a bar stock and then is etched, so that the manufacture of the microstructure on the curved surface is realized. Compared with the traditional method for only manufacturing the microstructure on a plane, the rolling-forming manufacturing method can adopt an easier way to break through the limitation that the traditional methods of photoetching and micro-contact printing can only manufacture the microstructure on the plane, and the method can manufacture the precise microstructure on the curved surface. The template subjected to impressing can be repeatedly used after being washed. Compared with other micro-nano impressing methods, the manufacturing method capable of realizing high efficiency and low cost has relatively low requirement for the environmental cleanliness.

Description

technical field [0001] The invention relates to a microstructure manufacturing method, in particular to a microstructure roll forming manufacturing method on a curved surface. It achieves the manufacture of microstructures on curved surfaces by rolling the template on the outer surface of the bar and then etching it. It belongs to the technical field of microstructure manufacturing. Background technique [0002] Micro-contact imprinting technology is a kind of nano-imprinting technology, which was proposed by IBM and Harvard University, and its principle is most similar to the concept of stamping. The process uses a resilient stamp to transfer thiols to a gold or silver plated surface. Pour polydimethylsiloxane (PDMS) onto the mold containing the pattern, and the general mold can be obtained by optical, electron beam lithography, or by micro-mechanical structure processing or replication of other micro-structures. The stamp material is solidified in the mold, and the desi...
