Journal ArticleDOI
Towards the Fabrication of High-Aspect-Ratio Silicon Gratings by Deep Reactive Ion Etching
Zhitian Shi,Zhitian Shi,Konstantins Jefimovs,Konstantins Jefimovs,Lucia Romano,Lucia Romano,Lucia Romano,Marco Stampanoni,Marco Stampanoni +8 more
TL;DR: A modified Coburn–Winters model was applied in order to study the influence of key etching parameters, such as chamber pressure and etching power, and the recipe for deep reactive ion etching was carefully fine-tuned based on the experimental results.
Journal ArticleDOI
Laboratory X-ray interferometry imaging with a fan-shaped source grating
TL;DR: Fan-shaped G0 source gratings by modulating the electric field during the deep reactive ion etching of silicon were fabricated in this paper to improve the uniformity of the field of view.
Journal ArticleDOI
Optimization of displacement Talbot lithography for fabrication of uniform high aspect ratio gratings
TL;DR: In this paper, a beating-free grating with pitch size of 1 μm and aspect ratio of 54:1 was demonstrated, and a proper scan range compensated the defect.
Journal ArticleDOI
Fabrication of X-ray Gratings for Interferometric Imaging by Conformal Seedless Gold Electroplating.
Konstantins Jefimovs,Joan Vila-Comamala,Carolina Arboleda,Zhentian Wang,Lucia Romano,Zhitian Shi,Matias Kagias,Marco Stampanoni +7 more
TL;DR: In this paper, the authors presented a method to produce small pitch gratings for X-ray interferometric imaging applications, allowing the phase sensitivity to be increased and/or the length of the laboratory setup to be minimized.
