10001707 · 2018-06-19 · ·

An exposure method is provided. The exposure method includes coating a photo-curable material on a substrate, and exposing a portion of the photo-curable material by providing a first light source through an optical fiber to form a first photo-cured material. The optical fiber includes a light output end and a cone portion that tapers toward the light output end. The photo-curable material not exposed by the first light source is removed while leaving the first photo-cured material. Exposure equipment for performing the exposure method and a 3-dimensional structure formed thereby are also described.

09939724 · 2018-04-10 · ·

A photolithography method and system based on a high step slope are provided. The method includes: S1, manufacturing a sacrificial layer with a high step slope on a substrate; S2, adopting a spin-on PR coating process to cover the sacrificial layer with a photoresist layer to form a photolithographic layer; S3, forming a mask pattern and a compensation pattern on a mask; and S4, performing photolithography processes, by a photolithography machine, on the photolithographic layer. By forming a slope-top compensation pattern and a slope compensation pattern on a mask to perform photolithography on the substrate of a sacrificial layer, a relatively wide compensation pattern is set in a part of the top of the slope with a small thickness, thereby compensating the overexposure at the top of the slope, reducing the error in the photolithographic pattern, and improving the precision of photolithography of the high step slope.

Microstructure synthesis by flow lithography and polymerization

In a method for synthesizing polymeric microstructures, a monomer stream is flowed, at a selected flow rate, through a fluidic channel. At least one shaped pulse of illumination is projected to the monomer stream, defining in the monomer stream a shape of at least one microstructure corresponding to the illumination pulse shape while polymerizing that microstructure shape in the monomer stream by the illumination pulse. An article of manufacture includes a non-spheroidal polymeric microstructure that has a plurality of distinct material regions.

Etching and thinning for the fabrication of lithographically patterned diamond nanostructures
12184259 · 2024-12-31 · ·

A back side of a diamond or other substrate is thinned using plasma etches and a mask situated away from the back side by a spacer having a thickness between 50 m and 250 m. Typically, a combined RIE/ICP etch is used to thin the substrate from 20-40 m to less than 1 m. For applications in which color centers are implanted or otherwise situated on a front side of the diamond substrate, after thinning, a soft graded etch is applied to reduce color center linewidth, particularly for nitrogen vacancy (NV) color centers.
