Abstract

The invention discloses a nanoimprint template and a manufacturing method thereof, for solving the poor peeling problem due to the relatively high segment gap of the nanoimprint template in a joint overlap area in the prior art. The manufacturing method of the nanoimprint template comprises the steps of: forming a groove in a pre-set area on one surface of a substrate film used for coating an imprint adhesive, wherein the pre-set area is an area that the imprint adhesives in adjacent two coating surfaces are in joint overlap; coating the imprint adhesive in a first coating area and the groove,wherein the thickness of the imprint adhesive positioned in the groove is less than the depth of the groove; performing pattern imprinting on the imprint adhesive in the first coating area; coating the imprint adhesive in a second coating area and the groove, wherein the second coating area and the first coating area are adjacent two coating areas; and performing pattern imprinting on the imprintadhesives in the second coating area and the groove.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a nanoimprint template and a manufacturing method thereof. Background technique [0002] The development of the semiconductor manufacturing industry relies on the improvement of low-cost micro-pattern structure transfer technology, but with the continuous reduction of the feature size of the pattern, the traditional photolithography technology based on the wavelength of light is gradually unable to do what it wants. Nanoimprinting (NIL) is a method that directly uses mechanical contact extrusion to redistribute the imprinted material between the template and the substrate. Compared with traditional lithography technology, it has the characteristics of high resolution; compared with high-resolution focused ion beam lithography, electron beam lithography, X-ray lithography and other technologies, it has high yield, low cost, It can be mass-produced and other characteristics...
