“…To solve this issue, a large number of microspheres can be applied to the fabrication at the same time. One solution is to utilize the self‐assembly to distribute more microspheres . As shown in Figure 1d, the distribution of microspheres becomes close‐packed and ordered due to the tendency of reducing its free energy.…”

Photolithography is one of the most commonly used techniques in semiconductor manufacturing, which is the foundation for all the modern electronic device fabrication. However, deep and extreme ultraviolet lithographic systems as well as the corresponding photomasks are both relatively expensive. The fabrication methods are based on the low‐speed high‐cost electron‐beam lithography or focused‐ion‐beam etching. Therefore, a maskless high‐speed method is highly recommended for the micro/nano‐structure fabrication. Among all these maskless methods, direct laser writing (DLW) is an important and widely adopted micro‐processing technique. Based on the nonlinear exposure, the feature size can achieve down to tens of nanometers. However, the speed of DLW is a technical bottleneck. To overcome this issue, parallel DLW methods are developed, including the self‐assembly microspheres laser patterning, laser interference lithography, and multifocal array DLW. Herein, the principles, advantages, challenges, and applications of these parallel processing technologies are summarized. Nanoscale resolution for large area arbitrary periodic pattern fabrication is achieved. Meanwhile, these technologies have the unique ability to build 3D structures instead of conventional 2D patterns, which is the direction of future micro/nano‐fabrication. These techniques are widely applied to surface processing and functional device fabrication in the field of sensing, solar cells, and metamaterials.

“…However, the situation is more complex near the scattering obstacles [3]. Generally, it is well-documented theoretically and experimentally that electromagnetic intensities near the scattering domains may significantly exceed the intensity of an incident beam [4,5]. This is most typically due to morphology-dependent resonances especially manifested near metal interfaces [6] or metallic particles [7,8].…”

This paper analyzes the optical behavior of an electrically charged spherical particle. The theoretical conditions for charge-induced resonances are specified through the Mie expansion coefficient a n that is treated analytically. It is shown that the conditions for normal mode generation change with the order of the expansion coefficient, thus resulting in a complex optical response of charged spheres. The previously undisclosed analytical formulation of resonance conditions is a main strength of this paper and our approach. The theoretical findings could have important implications for laser beam modulation devices, as well as photonics.

We have investigated the optical resonance and near field inside and under absorptive polystyrene (PS) microspheres on Si wafers. Near field flat plane images of PS microspheres were numerically simulated. Nanostructures were prepared on Si substrates using the regular two dimensional (2D) arrays by a single pulsed laser irradiation (KrF, lambda = 248 nm). Periodical PS nanoparticle, PS nanoflowers and Si nanobumps were fabricated by different laser fluence. Mechanisms for PS particle size reduction and Si nanobump formation by laser irradiation were discussed on the base of the theoretical calculations. Good agreement between theoretical calculations and experimental results has been observed.
