Abstract:
A method of making nanostructures including: locating a photoresist mask layer on a substrate, the thickness of the photoresist mask layer is H; forming a patterned mask layer includes a plurality of stripe masks, a spacing distance between adjacent stripe masks equals L; depositing a first thin film layer along a first direction, the thickness of the first thin film layer is D, a first angle between the first direction and a direction along the thickness of stripe masks is θ 1 , θ 1 <tan −1  (L/H); depositing a second thin film layer along a second direction, a second angle between the second direction and the direction along the thickness of stripe masks is θ 2 , θ 2 <tan −1 [L/(H+D)], 0<L−H tan θ 1 −(H+D)tan θ 2 <10 nm, the first thin film layer partly overlaps with the second thin film layer to form an overlapping structure; etching the first thin film layer and the second thin film layer to obtain a nanoscale microstructure.

Claim (Index 1):
A method of making nanostructures, comprising:\n locating a photoresist mask layer on a substrate, wherein a first thickness of the photoresist mask layer equals H; forming a patterned mask layer by exposing and developing the photoresist mask layer, wherein the patterned mask layer comprises a plurality of parallel and spaced stripe-shaped shield, a spacing distance between adjacent stripe-shaped shield equals L, a top surface of the patterned mask layer away from the substrate defines a first area I, a side surface of the patterned mask layer defines a second area II, a surface of the substrate exposed between adjacent stripe-shaped shield defines a third area III; depositing a first thin film layer on the substrate along a first direction, a second thickness of the first thin film layer equals D, a first angle between the first direction and a thickness direction of the patterned mask layer equals a first angle \u03b8 1 , \u03b8 1 <tan \u22121  (L/H); depositing a second thin film layer on the substrate along a second direction, a second angle between the second direction and the thickness direction of the patterned mask layer equals a second angle \u03b8 2 , \u03b8 2 <tan \u22121 [L/(H+D)], 0<L\u2212H tan \u03b8 1 \u2212(H+D)tan \u03b8 2 <10 nm, the entire second area II is covered by the first thin film layer or the second thin film layer, the first thin film layer partly overlaps with the second thin film layer to form an overlapping structure and a non-overlapping structure; removing the plurality of stripe-shaped shield; dry etching the first thin film layer and the second thin film layer to obtain a nanoscale microstructure, wherein a first width of the nanoscale microstructure equals a second width of the overlapping structure, and the non-overlapping structure is removed by the dry etching.
